Definitions

  • This invention relates to a mixing method and mixing apparatus for mixing a base fluid and a particulate solid to form a mixture which is preferably substantially homogeneous, and relates more particularly but not exclusively to a method and apparatus for mixing a water-based drilling mud with a polymer additive.
  • a mixing method for mixing a base fluid and a particulate solid said mixing method being characterised by the steps of introducing at least one stream of the base fluid into a mixing region in a manner to cause reduction of the supportive surface area of the base fluid, simultaneously introducing the particulate solid into the mixing region to form a mixture of the base fluid and the particulate solid in which the particulate solid is substantially dispersed in the base fluid, and simultaneously discharging the mixture from the mixing region.
  • Said reduction of the supportive surface area of the base fluid may be accomplished by applying forces to said at least one stream of the base fluid that cause said at least one stream of base fluid to break up into droplets in said mixing region.
  • Said reduction of the supportive surface area of the base fluid may additionally or alternatively be accomplished by simultaneously introducing at least two streams of base fluid into said mixing region with mutually conflicting in-stream velocity components, and more preferably by simultaneously introducing two streams of the base fluid into said mixing region from the same general direction and with mutually oppositely directed swirls.
  • Air may be simultaneously injected into said mixing region, preferably in the same general direction as said two streams of the base fluid when the base fluid is so introduced.
  • Introduction of the particulate solid into said mixing region may be accomplished either by induced flow (e.g. by suction) or by forced flow (e.g. by air-blown injection).
  • Mixture discharged from said mixing region may be directed into an expansion region to undergo further blending therein, preferably to an extent that substantially homogenises the mixture.
  • mixing apparatus for mixing a base fluid and a particulate solid
  • said mixing apparatus being characterised by a mixing chamber defining a mixing region therein, base fluid introduction means to introduce at least one stream of the base fluid into said mixing region in said mixing chamber in a manner to cause reduction of the supportive surface area of the base fluid in use of said mixing apparatus, particulate solid introduction means simultaneously to introduce the particulate solid into said mixing region in said mixing chamber to form a mixture of the base fluid and the particulate solid in which the particulate solid is substantially dispersed in the base fluid in use of said mixing apparatus, and mixture discharge means simultaneously to discharge said mixture from said mixing region in said mixing chamber in use of said mixing apparatus.
  • Said mixing apparatus preferably comprises force application means for applying forces to said at least one stream of the base fluid that causes said at least one stream of base fluid to break up into droplets in said mixing region in said mixing chamber in use of said mixing apparatus.
  • said base fluid introduction means may be such as simultaneously to introduce at least two streams of the base fluid into said mixing region in said mixing chamber with mutually conflicting in-stream velocity components in use of said mixing apparatus, and more preferably such as simultaneously to introduce two streams of the base fluid into said mixing region in said mixing chambers from the same general direction and with mutually oppositely directed swirls in use of said mixing apparatus.
  • Said mixing apparatus preferably further comprises air injection means for simultaneously injecting air into said mixing region in said mixing chamber in use of said mixing apparatus, preferably in the same general direction as said two streams of the base fluid when the base fluid is so introduced.
  • Said mixing apparatus may comprise suction means to suck the particulate solid into said mixing region in said mixing chamber, or said mixing apparatus may comprise injection means to inject the particulate solid into said mixing region in said mixing chamber.
  • Said injection means may comprise an air-blown injector.
  • Said mixing apparatus may further comprise an expansion chamber defining an expansion region therin, said expansion chamber being coupled to said mixing chamber such that said expansion region is downstream of said mixing region in use of said mixing apparatus.
  • a helical flow director means may be mounted in said expanison chamber to be downstream of said expansion region, said helical diverter means being constructed or adapted to act on mixture flowing out of said expansion region in use of said mixing apparatus to divert such mixture into a helical flow pattern.
  • a mud mixer for substantially homogenously mixing an initially particulate solid additive into substantially continuous flow of liquiform drilling mud
  • said mud mixer being characterised by a mixing chamber having two mud injection nozzles each disposed to inject a respective stream of drilling mud in the same general direction into said mixing chamber in use of said mud mixer, said mixing chamber further having an additive inlet for admitting a substantially continuous flow of said additive into said mixing chamber simultaneously with the two injected streams of mud in use of said mud mixer, said mud mixer further comprising a drilling mud inlet for receiving a substantially continuous flow of incoming liquiform drilling mud to be mixed with said additive, two mud conduits each having a respective upstream end and a respective downstream end, each of said downstream ends of said two mud conduits being coupled to a respective one of said mud injection nozzles, a mud flow splitter coupling said mud inlet to said upstream ends of said two mud conduits to split said incoming
  • Said mud mixer preferably further comprises an air injection nozzle disposed to inject a stream of air into said mixing chamber simultaneously with injection of said two streams of mud in use of said mud mixer.
  • Said air injection nozzle is preferably disposed to inject said stream of air in substantially the same direction as the general direction in which said two streams of mud are injected into said mixing chamber in use of said mud mixer.
  • Said two mud injection nozzles may be disposed at substantially the same height in said mixing chamber, and are preferably aligned to inject said two mud streams of mud substantially horizontally into said mixing chamber in use of said mud mixer.
  • said air injection nozzle may be disposed horizontally between and vertically beneath said two mud injection nozzles.
  • Said additive inlet is preferably disposed vertically above said two mud injection nozzles and a deflector surface may be disposed adjacent at least one side of said additive inlet to deflect at least a portion of incoming additive at least partly in said general direction of mud stream injection.
  • Said mud mixer preferably further comprises an expansion chamber coupled to and downstream of said mixing chamber to receive and contain expansion of mixture discharged from said mixing chamber in use of said mud mixer.
  • Said expansion chamber preferably has a helical flow diverter disposed adjacent the downstream end of said expansion chamber to induce helical flow in mixture departing said expansion chamber in use of said mud mixer.
  • Said mud mixer may have two additive conduits coupled to the upstream side of said additive inlet for receiving incoming additive from a selected one of two additive sources.
  • One such additive source may comprise an additive hopper preferably disposed for gravity feed to said additive inlet, and the other such additive source may comprise a pipeline for conveying additive in bulk to said additive inlet.
  • Each said additive conduit is preferably fitted with a respective additive flow control valve.
  • a mud mixer 10 comprises a mixing chamber 12 whose upstream end face 14 (the left end as shown in ghost outline in Fig. 1) mounts left and right mud injection nozzles 16 and 18 which are both aligned to discharge in the same general direction, which is substantially horizontal and left to right (see Fig. 1), through in slightly converging paths (see Fig. 2).
  • the nozzles 16 and 18 are individually fed with respective mud streams derived from a flow conditioner 20 coupled between a mud inlet 22 of the mixer 10 and the nozzles 16, 18.
  • Incoming liquid drilling mud which is to be mixed with additive, arrives at the mixer inlet 22 from any suitable source (not shown), and enters a flow-splitting manifold 24 wherein the incoming mud is substantially symmetrically split into volumetrically equal left and right mud streams.
  • These two mud streams are respectively conveyed through left and right mud conduits 26 and 28 whose respective upstream ends 30 and 32 are coupled to the twin outlets of the flow-splitting manifold 24.
  • the respective downstream ends 34 and 36 of the mud conduits 26 and 28 are coupled to the left and right mud injection nozzles 16 and 18 respectively.
  • a respective swirl inducer (not visible), each conveniently in the form of an elongated spiral strip of a form which induces a substantial rotational component in the stream of mud flowing longitudinally through the mud conduits 26, 28.
  • Any other suitable form of swirl inducer is possible within the scope of the invention).
  • these two swirl inducers are oppositely handed to produce mutually opposite directions of the rotational component in the two mud streams being conveyed in use to the nozzles 16 and 18, i.e.
  • a notional section of the downstream end of the flow conditioner 20 transverse to its longitudinal axis joining the inlet 22 to the mixing chamber 12 would manifest the two mud streams rotating in mutually opposite directions.
  • a hypothetical observer in the mixing chamber 12 looking upstream towards the mud inlet upstream end face 14 would observe the mud stream discharged from the left nozzle 16 rotating anti-clockwise while the mud stream discharged from the right nozzle 18 was rotating clockwise, or vice versa.
  • This induced mutual contra-rotation of the two mud streams injected into the mixing chamber 12 has the operationally important effect of causing a reduction of the supportive surface area of the incoming liquid mud, preferably by the hydrodynamic mechanism of causing incoming mud to break up into droplets.
  • an additive inlet 38 for admitting the initially particulate solid additive to the mixing chamber 12.
  • the additive inlet 38 is coupled to two alternate additive supplies by means of a dual-inlet, single-outlet pipe coupling 40.
  • One inlet 42 of the coupling 40 is coupled to an additive feed hopper 44 by way of an additive flow-controlling butterfly valve 46.
  • the other inlet 48 of the coupling 40 is coupled through a further additive flow-controlling valve 50 to a pipeline (not shown) for delivering bulk supplies of additive to the mixer 10.
  • valves 46 and 50 Normally, only one of the valves 46 and 50 would be open in use of the mixer 10 to receive additive from a single one of the alternate sources, but it is conceivable that in certain circumstances both valves 46 and 50 would be open simultaneously to deliver additives from both sources to the mixing chamber 12 together. If additive were to be received from a single source without provision for alternate supply, the coupling 40 could be eliminated and the additive inlet 28 then coupled directly to that one source (via a flow-controlling valve, if necessary). Conversely if additive were to be received from more than two sources, the coupling 40 could be modified accordingly to couple the inlet 38 to the requisite number of sources. Entry of the additive through the inlet 38 into the mixing chamber 12 can be induced, e.g. by suction applied in the chamber 12, or forced, e.g. by air-blown injection of the additive.
  • the highly turbulent mud in the mixing chamber 12 rapidly entrains and disperses the incoming additive on a continuous basis to form a relatively uniform and homogeneous mixture without the previously described disadvantages of prior art mud mixing systems and procedures. Entrainment of the additive into the mud can be assisted by providing a deflector plate 52 in the mixing chamber 12 to deflect the descending stream of additive in the same general direction as that in which the mud streams are injected through the nozzles 16 and 18.
  • compressed air may be injected into the mixing chamber 12 simultaneously with the mud streams and the additive.
  • Air injection is preferably carried by means of a venturi jet 54 which is preferably mounted on the upstream end face 14 of the mixing chamber 12, laterally mid-way between the mud nozzles 16 and 18 and slightly below them.
  • the air jet 54 is preferably aligned to discharge in the same general direction as that of mud stream injection, and is fed with compressed air via a pipe 56 supplied from a suitable source (not shown).
  • the jet 54 and its air supply are preferably arranged so that air injection operation increases the velocity of mud discharge from the nozzles 16 and 18 by decreasing the obstructive air pressure acting against the jets of mud.
  • the downstream and of the mixing chamber 12 (i.e. the end of the chamber 12 longitudinally opposite the upstream end 14) is preferably directely connected to a contiguous cylindrical expansion chamber 58 forming an optional part of the mixer 10.
  • the expansion chamber 58 accomodates the mixture discharged from the mixing chamber 12 and is particularly useful in containing the mixture as injected compressed air expands towards ambient pressure downstream of the mixer 10.
  • Turbulent flow in the mixture passing through the expansion chamber 58 is preferably returned to a rotary flow pattern by an optional helical diverter plate (not shown) mounted in the downstream end 60 of the expansion chamber 58, so to improve blending and homogenisation of the mud/additive mixture discharged from the mixer 10.
  • the helical diverter plate also causes the mixture to spray in an arcing motion from the downstream end 60 of the mixer 10 to create further shear stress on the mixture and so enhance homogenisation.
  • the mixer 10 As applied to the blending of high molecular weight encapsulating and/or viscosifying polymers into water-based drilling mud (whether freshwater-based or sea water based), the mixer 10 will produce a substantially uniform and homogeneous mixture without the balling and other mixing defects of prior art mixing methods and apparatus.
  • the mixer 10 is not limited to the mixing of such substances, and can be applied, for example, to the mixing of other additives into drilling mud, and to the mixing of initially particulate solids into liquiform base fluids in general.
  • Modifications can be made to the exemplary structure of the mixer; for example while the incoming mud is split into two streams for injection into the mixing chamber in the illustrated embodiment, the mud or other liquiform base fluid could be injected as a number of streams which less than two or greater than two, and suitable swirl inducers other than helical plates can be employed to give the streams injected into the mixing chamber requisite mutually conflicting in-stream velocity components.
  • the invention is not restricted to the illustrated form of flow conditioner, any any suitable form of flow conditioner may be employed without departing from the scope of the invention.
  • the mixing chamber can have any suitable form, and is not restricted to the form shown in the accompanying drawings.
  • the injected streams need not be injected into the mixing chamber in the same general direction, so long as the injected stream or streams are injected into the mixing region in a manner to cause reduction of the supportive surface area of the drilling mud or other base fluid. While the additive is caused or allowed to descend into the mixing chamber from a single additive inlet in the illustrated embodiment, admission of the additive or other particulate solid into the mixing chamber can be other than vertically downwards, and/or from more than one inlet at a time.
