Definitions

  • hydrocarbon resources such as oil
  • the wellbore may produce liquid hydrocarbons as a water mixture.
  • separation devices such as hydrocyclones, may be used on the surface to remove the water, separating oil and water based on their different densities.
  • Hydrocyclones may also be used downhole, but the limited cross-sectional area of a borehole conventionally limits significant cyclonic action downhole. Energy can be wasted lifting the hydrocarbon and water mixture out of the well to remove the water on the surface. It is conventionally difficult to accomplish a significant oil-water separation downhole where the water component can sometimes be stored or even utilized for pressure maintenance, and it is also conventionally difficult to achieve a downhole separation that provides environmentally pure water.
  • An example system includes parallel arrays of downhole hydrocyclones, with multiple of the parallel arrays connected in hydraulic series to provide successive oil-water separation stages downhole.
  • the arrays of hydrocyclones connected in hydraulic parallel, and the parallel arrays connected in hydraulic series are flow balanced and pressure balanced with respect to each other and situated into a housing suitable for the limited space of a downhole environment.
  • the parallel arrays provide high throughput, while the multiple stages connected in series provide high separation resulting in high oil yield and substantially clean water.
  • Fig. 1 is a diagram of a section of an example parallel array of oil-water separators, such as hydrocyclones, for downhole service.
  • Fig. 2 is a schematic diagram of series hydraulic connection of two parallel arrays of oil-water separators for downhole service.
  • FIG. 3 is a diagram of an example multi-stage oil-water separation system for downhole service.
  • FIG. 4 is a diagram of another example multi-stage oil-water separation system for downhole service.
  • Fig. 5 is a diagram of a transition area and fluid flows between oil-water separators, for downhole service.
  • Fig. 6 is a diagram of a transition area and fluid flows between oil-water separators, for downhole service, including oil flow into a common oil line.
  • Fig. 7 is a flow diagram of an example method of constructing a multi-stage downhole oil-water separator.
  • This disclosure describes multi-stage downhole oil-water separators.
  • An example system combines multiple separators, such as hydrocyclones, into a parallel array for high throughput downhole, and connects multiple instances of the parallel array in series to make separation stages, all packaged to fit in the cross-sectionally limited space of a downhole wellbore.
  • the parallel array of multiple hydrocyclones in each separation stage ensures a high downhole flow rate through each stage, while the serial arrangement of successive hydrocylone stages can achieve a high purity of the oil and water phases.
  • the example system packs numerous hydrocyclones into the limited bore space of a well casing by staggering the placement of individual hydrocyclones with respect to each other according to their geometry, and by interleaving, as needed, the parallel and serial fluid connections between individual hydrocyclone devices, and between serial stages.
  • the example system may also include flow rate mechanisms and pressure-balancing devices, especially between serial stages, that balance flow rate and pressure differences to enable the separation stages to work with each other and provide smooth and efficient oil and water phase separation.
  • a series of flow rate controllers may govern the flow of an oil stream that has been separated off by the hydrocyclones.
  • This downhole "miniaturization" of an entire oil-water separation system can simplify bottleneck congestion of processing devices at surface facilities and can save the cost of energy needed for lifting an oil-water mixture to the surface before rejecting the water from the mixture.
  • the example system processes mixtures with an initial oil concentration that is between 5% and 30% of the oil-water mixture, but the example system can be used successfully for inlet oil concentrations less than 5%.
  • the example system can also provide a water quality that satisfies both disposal requirements and local environmental regulations.
  • Fig. 1 shows an example section of a parallel array 100 of separators, such as oil-water hydrocyclone separators.
  • the example section of the parallel array 100 may contain "n" separators in parallel, although two separators 102 & 104 are shown in the example section of a parallel array 100 in Fig. 1 .
  • each hydrocyclone separator is connected in parallel fluid communication with the other hydrocyclone separators in the parallel array 100.
  • Parallel fluid communication or connection in parallel means that at least the inputs 106 & 108 of each hydrocyclone separator 102 & 104 in the parallel array 100 are connected together for common fluid flow via a common tube, space 110 or manifold.
  • the oil outputs 112 & 114 of each separator 102 & 104 in the parallel array 100 may be fluidly connected together, either at a common tube 116, space, or manifold.
  • the water outputs 118 & 120 of each separator 102 & 104 in the parallel array 100 are preferably assigned separate individual tubes 138 & 140 for each hydrocyclone, but may also be connected together, if the hydrostatics allow, either at a common tube, space or manifold.
  • the example section of a parallel array 100 includes a housing 124 that may define the section and may provide a modular parallel array 100 that can be interchanged in a longer assembly. Or the housing 124 may be one long casing for several fixed arrays.
  • the housing has an inlet end 126 for receiving a fluid mixture and an outlet end 128 that includes a discharge head 130 having an overflow port 132 (for separated oil) and two underflow ports 134 and 136 (for the water or water mixture that has been deoiled).
  • an overflow port 132 for separated oil
  • two underflow ports 134 and 136 for the water or water mixture that has been deoiled.
  • hydrocyclone separators 102 & 104 are shown as arranged in the same general orientation for separating phases of the fluid mixture. In a given parallel array 100, however, the hydrocyclone separators do not necessarily have to be placed in the same orientation.
  • Each hydrocyclone 102 & 104 has an inlet 106 & 108 that is at least fluidly connected to the housing inlet end 126.
  • Hydrocyclones 102 & 104 have overflow exits 112 & 114 for withdrawing overflow fractions (oil), and underflow exits 118 & 120 for withdrawing underflow fractions (water).
  • the overflow exits 112 & 114 of hydrocyclones 102 & 104 are connected into a tubing 116, which leads to the overflow port 132 on the discharge head 130.
  • the underflow exits 118 & 120 of hydrocyclones 102 & 104 are fluidly connected to tubings 138 & 140, respectively.
  • the tubing 138 & 140 from underflow exits 118 & 120 are fluidly connected to the underflow ports 134 & 136 on the discharge head 130.
  • An oil-water mixture enters the hydrocyclone separators 102 & 104 through the housing inlet end 126.
  • the oil-water mixture flows through the hydrocyclone separators 102 & 104 and is separated into phases by cyclonic action based on the relative densities of the components to provide an oil-rich flow at the overflow exits 114 & 116 and a water-rich flow at the underflow exits 118 & 120.
  • the underflow may be substantially clean water after being deoiled by a series of the parallel arrays 100, or contain a sufficiently small quantity of oil to be returned to a geological stratum of the well for disposal. In some cases, the water may be used for well pressure maintenance.
  • the water-bearing underflows 118 & 120 from individual hydrocyclones 102 & 104 have separate tubings 138 & 140 leading to the discharge head 130, while the oil-bearing overflows 112 & 114 from individual separators 102 & 104 are connected into the same tubing 116 to the discharge head 130.
  • This configuration is advantageous for fluid dynamics because the underflow (e.g., water) is relatively dense and more viscous as compared to the hydrocarbons, and there is more fluid in the water phase traversing the series of parallel arrays 100.
  • Fig. 2 shows an example schematic diagram 200 for connecting multiple instances of the example parallel array 100 of Fig. 1 in series, downhole.
  • Series connection means that the water-rich output (e.g., hydrocyclone underflow) from a previous parallel array 100 becomes the input for a next instance of the parallel array 100', while the oil-rich output (e.g., hydrocyclone overflow) may be transported away in a common tube 116, separately.
  • water-rich output e.g., hydrocyclone underflow
  • oil-rich output e.g., hydrocyclone overflow
  • Downhole oil-water separation may be either static separation, utilizing for example one or more hydrocyclone "liners,” or dynamic separation which utilizes a centrifuge separator rotating at the same operating speed as an electrical submersible pump (ESP).
  • Hydrocyclone liners are available in different diameters. Small diameter liners, known as deoilers, have high-quality separation performance but are flow rate limited. To overcome the flow rate limitation of small deoilers, a greater number of multiple deoilers are operated in hydraulic parallel in a respective parallel array 100.
  • an individual deoiler hydrocyclone e.g., 1 inch (2.54 cm) diameter
  • bbl barrels per day
  • multiple instances of the small deoiler hydrocyclones connected in parallel may handle the flow rate of a well pumped by artificial lift.
  • Fig. 2 shows a serially connected system 200 of only two parallel arrays 100 & 100' (each parallel array 100 represented by a single symbol), but an example multi-stage downhole separation system (300 in Fig. 3) may have three or more parallel arrays 100 in series.
  • System 200 includes a first parallel array 100 of separators that provides a stage of separation (e.g., bulk separation of oil from water) and a second parallel array 100' of separators, fluidly connected in hydraulic series.
  • the total inlet fluid 202 e.g., wellbore fluid or formation fluid
  • the first parallel array 100 separates the inlet fluid stream 202 into a first output stream 206 richer in water than inlet stream 202 and a first production stream 208 richer in hydrocarbon (e.g., oil) than the inlet stream 202.
  • the first production stream 208 is discharged from an outlet 210 (e.g., oil outlet, production outlet) and may be directed to the surface as production outlet stream 116.
  • the first water stream 206 is discharged from an outlet 212 (e.g., water outlet, injection outlet) to become the inlet stream (via inlet 214) for the second stage parallel array 100'.
  • the first water stream 206 is separated into the second water stream 216 and a second production stream 218.
  • the second water stream 216 is discharged from an outlet 220 into succeeding stages (not shown) to become the water-rich final output of the system, with most oil removed.
  • the second production stream 218 is discharged through an outlet 222 and may be produced to the surface in common line 116.
  • the first production stream 208 may bypass the second parallel array 100' and be produced directed to the surface (e.g., production stream 116) or it may be combined with the second production stream 218 (as shown) for transport to the surface. Due to the additional pressure drop from the second parallel array 100' separator stage, the second stage production stream 218 will have a lower pressure than the first production stream 208.
  • the pressures must be balanced, for example via pressure- balancing device 224.
  • Pressure-balancing device 224 is an apparatus for controlling or regulating fluid pressure, for example, by reducing the flow rate of the first production stream 208 and/or increasing the pressure of second production stream 218.
