Definitions

  • the invention relates to a method for the preparation and at least partial recycling of drilling mud that occurs during an earth drilling.
  • drilling fluids When drilling earth bores (for example horizontal bores or vertical bores, such as bores for thermal probes), drilling fluids are used that are pumped into the borehole via the drill head.
  • the drilling fluids are composed of various substances, the main component of which is usually water. Bentonite is usually used as an aggregate, which forms a suspension together with the water content.
  • drilling fluids contain additional additives that are adapted to the subsoil to be drilled.
  • the task of the drilling fluids is to cool and lubricate the drilling head, stabilize the drilling channel and remove the soil.
  • the used drilling fluid is pumped out of the borehole again and then contains material from the borehole.
  • the material from the borehole can also include pollutants such as heavy metals or leached contaminated sites.
  • U.S. 4,635,735 A discloses an oil drilling apparatus in which drilling mud is continuously examined for hydrocarbons by analyzing gas deposits from the drilling mud. The aim of this is to locate oil and gas when drilling.
  • US 2010/193249 A1 discloses a closed circuit of drilling fluid in the production of a well.
  • EP 2 530 237 A1 also describes a drilling process with a closed circuit in which drilling mud is recycled as far as possible at the drilling machine.
  • the object of the present invention is therefore to propose a way of at least partially recycling the drilling sludge that arises during drilling work.
  • the invention proposes a method according to claim 1, which is also explained in more detail in the description of the figures.
  • the approach according to the invention is not only limited to the method, as just stated, but also includes a processing system for processing drilling sludge that occurs during an earth drilling, the processing system having at least one input bunker, at least one processing or separation stage for separating the soil or .
  • the approach according to the invention comprises a system for the processing and at least partial recycling of drilling mud that occurs during an earth drilling, which is used in particular to carry out the method according to the invention, the system being a processing plant as just specified, a drilling device that collects the drilling mud that occurs in a collector and has a transport means which is used to transport drilling fluid held in the processing plant to the drilling device at the location of the earth drilling and to transport drilling mud collected in the collector of the drilling device to the processing plant.
  • the invention proposes a third way of using the drilling mud. It is a complete recycling process, which is described by the process, the processing plant and the system, for the processing and at least partially Recycling of the drilling sludge produced during earth drilling.
  • Several positive effects are in the foreground: First, the precious water is used several times in the described elimination process, which conserves this natural resource.
  • the recycling process also produces bentonite that is either excreted as bulk goods or, because it is dissolved in the water, is still in the drilling fluid after the recycling step.
  • the proposal according to the invention therefore also reduces the consumption of bentonite, since this additive is also used several times.
  • the drilling fluid supply is advantageously located at the processing plant, which means that the transport vehicles used are always loaded, once with prepared drilling fluid to the construction site and on the way back with (contaminated) drilling mud.
  • the central processing plant guarantees a high processing quality.
  • the processing plant can be capacitively designed so that effective process control is possible, which is also the basis for an economically successful concept.
  • the separated soil or rock components are cleverly stored in the area of the processing plant and can be reused there, for example, as building materials, for example in road construction and the like. Since the constituents have different grain sizes, mechanical separation will be carried out with a large number of sieves and the like; the fractionation of the material that takes place in this way is advantageous for the further use of these materials.
  • the central use of a processing plant also allows a complete documentation of the utilization of the drilling sludge created at the construction site and thus also ensures that this material is not spread on agricultural land, for example, and then possibly ends up in the food chain.
  • the system according to the invention also ensures that the drilling mud that arises is actually disposed of by the construction site, since the data documentation means that it is known what amount of drilling fluid was delivered there.
  • the proposal according to the invention combines an economically viable concept with a high level of environmental protection in a simple and convincing manner.
  • the proposal advantageously provides that drilling mud delivered to the processing plant is analyzed, and depending on the analysis result either a separation of the soil or rock components from the drilling mud, a separation of the soil or rock components from the drilling mud and a subsequent one Conditioning of the soil or rock components or conditioning of the drilling mud and subsequent disposal takes place.
  • the further processing, preparation or separation of the drilling mud then takes place.
  • a first variant it is provided that, if the analysis reaches a harmless result, only one (for example mechanical) separation of the soil or rock components from the drilling mud takes place.
  • a substance is discovered during the analysis that excludes conventional processing, there are basically at least two further variants for the further procedure. Often times the harmful ingredient is non-volatile i.e.
  • the soil or rock components are separated from the drilling mud, for example with the help of a thermal separation step, and then the remaining soil or rock components are carried out with it conditioned to the pollutant.
  • Conditioning is understood to mean the addition of a binding agent and the processing of the drilling mud into a solid that cannot be washed out, for example a concrete, that is, under certain circumstances, an otherwise usable product. Alternatively, this resulting solid can also be disposed of.
  • the analysis provided here takes place in an automated step, paying attention to common pollutants such as heavy metals, etc.
  • this is preferably implemented in such a way that an analysis stage is provided in the conveying direction of the drilling mud before, in or after the input bunker, and the drilling mud is fed to different processing or separation stages for processing depending on the analysis result.
  • the delivered drilling mud is stored in the input bunker, which represents a corresponding work supply for the processing plant. It can be advantageous for the analysis to be carried out before the loading into the entry bunker, for example in order to take the delivered cargo to another location after the analysis and to feed it there for processing. Alternatively, it is of course possible that the analysis or analysis stage in or after the input bunker is provided, and then depending on the analysis result, quasi in the river, the drilling mud is fed to one or the other processing.
  • conditioning takes place by adding a binding agent, such as in particular cement, lime or a cement-lime mixture.
  • a binding agent such as in particular cement, lime or a cement-lime mixture.
  • this binding agent does not impair the setting of the drilling mud to form a product with the usual concrete strength.
  • the drilling mud contains bentonite, which binds a lot of moisture and also contains other additives such as polymers, etc.
  • a concrete produced in this way can no longer be washed out chemically, which in particular improves its landfill and storability, but also its further use, for example as a building material or aggregate in road construction, or as liquid soil in sewer construction, etc.
  • the use of cement, lime or a lime-cement mixture for conditioning of drilling mud that is produced during earth drilling, in particular containing bentonite and mixed with soil or rock components is proposed.
  • This proposal also solves the problem set at the beginning, because it provides a means for reusing the drilling mud at least partially, for example as aggregate or building material.
  • an interval is specified for the proportion of cement, lime or a lime-cement mixture in the use according to the invention, which is described by an upper and lower limit.
  • the following values are provided as the lower limit: 5, 8, 10, 12,% [weight] based on the mass of the drilling mud.
  • the lime-cement mixture has the following mixing ratios.
  • the proportion of lime in the mixture is also described by an interval:
  • the following values, for example, are provided as the lower limit: 5, 10, 15, 25, 35, 40% [weight] based on the mass of the mixture.
  • the following values are provided as the upper limit: 30, 40, 50, 60, 65, 75, 85, 90% [weight] based on the mass of the mixture.
  • the proportion of cement in the mixture is also described by an interval: For example, the following values are provided as the lower limit: 5, 10, 15, 25, 35, 40% [weight] based on the mass of the mixture.
  • the following values are provided as the upper limit: 30, 40, 50, 60, 65, 75, 85, 90% [weight] based on the mass of the mixture.
  • the disclosure of this application encompasses the set of all intervals defined by all possible combinations of the aforementioned upper and lower limits. According to the invention, the mixture can also have further constituents, which is why the two proportions do not necessarily have to total 100%. It is clear that the disclosure excludes such variants which in the sum of the individual components exceed 100%.
  • the drilling mud is separated by a thermal separation stage.
  • This separation stage is relatively energy-intensive, it leads to a considerable reduction in material, ie mass, which is particularly advantageous for a subsequent landfill.
  • the thermal separation stage is also used if a pollutant was found during the analysis provided on the input side, which, for example, can only be isolated in a suitable manner by the thermal separation stage.
  • the water evaporated in the thermal separation stage is condensed and the condensation heat released in the process is used to preheat the drilling mud.
  • the condensation heat released in the process is used to preheat the drilling mud.
  • the composition of the drilling fluid is monitored in the drilling fluid reservoir and, if necessary, drilling fluid suspension agent is added in a controlled manner. Such a procedure ensures that the drilling fluid that is kept available has a sufficient and guaranteed quality. It cannot be ruled out that the preparation of the drilling mud also removes drilling fluid suspension medium from the drilling mud or the liquid, which is then disadvantageous in further use.
  • drilling mud is separated mechanically, in particular by sieving or centrifuging. Such processing is more cost-effective and is particularly useful if no harmful pollutants were found during the analysis.
  • the precipitated or rock components are stored.
  • Storage within the meaning of the invention is, for example, that mechanically or thermally separated constituents of the drilling mud are conditioned and deposited.
  • the invention also encompasses the fact that the separate components, sorted according to grain size and / or intended use, are stored as bulk goods or packaged sacked goods or the like.
  • FIG. 1 the entire circuit of the drilling fluid is shown schematically.
  • the illustration begins with the filling of the storage container 23 on the drilling device 2 with fresh drilling fluid, which was delivered here by the means of transport 3, 3a.
  • the fresh drilling fluid is then fed from the storage tank 23 to the drilling device 2 via the line 21 for cooling and lubrication, as described, when the drilling device 2 (an exemplary horizontal drilling device) is in operation.
  • Used drilling fluid is collected as drilling mud via the line 22 in the collector 20 and collected there until the means of transport 3, 3b picks it up there, which is consequently the same means of transport 3, 3a that previously filled the fresh drilling fluid into the reservoir 23.
  • the transport means 3, 3c drives the drilling mud removed from the collector 2 to the input bunker 10 of the processing plant 1.
  • the analysis stage 11 in which an analysis of the delivered drilling mud is carried out and based on this analysis result a decision is made as to how the delivered drilling mud is processed with the aid of the various separation stages 12, 12a, 12b, 12c.
  • an automatically operating analysis stage 11 acts on the respective shut-off valves 14a, 14b, and 14c by means of corresponding actuating elements, and thus allows an automated flow of the drilling mud.
  • the first separation stage 12a is used for heavily soiled or contaminated drilling mud, in the direction of flow of the drilling mud in the drainage line 13, the second separation stage 12, 12 b for less soiled or contaminated drilling mud, and the last separation stage 12, 12 c only serves to separate the soil with a mechanical dominance - and rock components of drilling mud that is not contaminated per se. Therefore, the different concepts for the preparation or separation of the drilling mud fed into the separation stages differ from one another.
  • the first separation stage 12, 12 a conditions the drilling mud in such a way that it can be stored in the landfill 4.
  • the conditioning takes place by adding binding agent via the filling area 15 at the separation stage 12a.
  • the binding agent for example lime, cement or a lime-cement mixture, leads to a concrete-like bond between the drilling mud and the For example, it can be landfilled, as pollutants can no longer be washed out of them.
  • the second separation stage 12b is designed as a thermal separation stage and reduces the mass and volume of the drilling mud by evaporating the water in the drilling mud.
  • a water vapor cloud 16 is therefore also indicated here and the separation stage 12b comprises a heater 17. Instead of losing the evaporated water in a water vapor cloud 16, provision is also made for the evaporated water to be condensed back in a heat exchanger and then fed to the drilling fluid reservoir 19 via line 18 .
  • the third separation stage 12c is also connected to the drilling fluid reservoir 19 via a line 100.
  • This third separation stage 12c is designed as a mechanically acting separation stage.
  • mechanical concepts are used which, for example, use gravity, different masses or different grain sizes of the constituents for a division / separation.
  • the separation stage 12c therefore comprises, for example, one or more components of the following group: vibrating sieve, cyclone, sieves, shakers, centrifuges (although this list is not exhaustive).
  • this separation stage also comprises several components of the above-described group arranged one behind the other.
  • the reference number 5 denotes a heap of rubble of the soil and rock components that occur as bulk material and are produced in this separation stage 12c. This material can be reused, for example, as building material in road construction or as an aggregate in other applications.
  • the drilling fluid reservoir 19 holds new, ready-mixed drilling fluid intended for use, which is then filled into the transport vehicle 3, 3d as required in order to transport it to the construction site where the drilling device 2 is located.
  • a mixer 101 is provided in the drilling fluid reservoir 19, which ensures that the prepared drilling fluid is homogenized.
  • a sensor 102 is provided which monitors the quality of the drilling fluid held in reserve and in particular monitors the proportion of drilling fluid suspension medium. If the proportion of drilling fluid suspension medium is too low, then the drilling fluid suspension medium is refilled from the supply 103. This can also be done automatically.
  • the mixer 101 ensures a uniform distribution of the newly introduced drilling fluid suspension agent.
  • a tanker vehicle As a means of transport 3, a tanker vehicle is seen in this overview, but without restricting the invention, in particular the system according to the invention, to this. It is clear that a container transporter is also provided instead of a tanker as the means of transport 3, who unloads or loads the corresponding containers at the construction site or the processing plant 1.
