Definitions

  • the invention relates to a mixing system as used for the preparatory mixing of a drilling fluid for horizontal drilling.
  • the necessary quantity of drilling suspension cannot generally be accurately estimated, so that the drilling fluid is often not completely used up after the end of the drilling operation and has to be disposed of. If the drilling fluid is left in the tank, subsequent swelling of the drilling fluid may occur. Because of the increased viscosity, problems may arise during drilling when this drilling fluid is once again used. In the winter, moreover, it is impossible to rule out frost damage to equipment by a drilling fluid that has not been completely used up.
  • the drilling fluid is generally fed to the drill by a high-pressure pump.
  • Such pumps are not generally self-priming pumps.
  • the use of a self-priming supercharge pump is necessary to charge the high-pressure pump on the suction side.
  • the use of such a supercharge pump also results in a substantial increase in cost.
  • the object of the invention is therefore to permit a simplified charging of a drilling system with a drilling fluid.
  • the achievement of the object is based on the principle of introducing additives, such as the pulverulent bentonite, upstream or downstream of the high-pressure pump.
  • the additive medium After the additive medium has been fed in, it passes with the service water into the high-pressure pump, where intensive mixing takes place.
  • a mixing section for further mixing may be provided downstream of the high-pressure pump.
  • a swelling section may also adjoin the mixing section if a particular duration of swelling is desirable.
  • the additive medium When the additive medium is introduced downstream of the high-pressure pump in the direction of flow, it is introduced in the region of the high-pressure jet of the high-pressure pump, which results in intensive mixing of the additive medium with the service water.
  • the feed-in section may also be adjoined by additional mixing and swelling sections.
  • the mixing system according to the invention allows continuous, in other words on-line, mixing of the additives for the drilling fluid with the service water. Additional storage tanks are thus avoided, so that the mixing system is of exceptionally small dimensions and can be used directly adjacent to the drill. Because of its small size, the mixing system may be designed as integral parts of mobile drills.
  • the liquid introduced on the suction side is, according to the invention, of low viscosity since it comprises either pure service water (fed in downstream of the high-pressure pump) or service water with bentonite that has not yet swelled (fed in upstream of the high-pressure pump).
  • the compact construction achieved by means of the invention makes it possible to connect the mixing system to mobile drills of any desired size, as a high degree of variability exists regarding the possible quantity admixed and the mixing performance.
  • the mixing system then merely needs to be connected to a hydrant on the construction site, the desired quantity of drilling fluid being available for the drilling operation in any combination of circumstances.
  • the storage container preferably used for the additives to the mixing system is a silo or a so-called “big bag”.
  • the mixing system according to the invention has a lower energy consumption and longer service life than conventional units, not least because of the elimination of the additional pumps needed in the prior art.
  • FIG. 1 shows a mixing system according to the invention with the suspension medium being fed in upstream of the high-pressure pump in the direction of flow,
  • FIG. 2 hows the mixing system according to FIG. 1 with feed lines for additives
  • FIG. 3 shows the mixing system according to FIG. 1 with a feed line for the additive medium downstream of the high-pressure pump
  • FIG. 4 shows the mixing system according to FIG. 3 with a feed line for additives
  • FIG. 6 shows the mixing system according to FIG. 5 with an additional feed line for additives.
  • the service water is fed to the mixing system according to this embodiment on the low-pressure side of a high-pressure pump, via a hydrant.
  • the mixing system On the low-pressure side, the mixing system also has a pressure-reducing valve 12 , via which the service water is fed to the high-pressure pump 7 via a filter member 13 and a shut-off valve 14 .
  • the service water feed can be turned on and off, and adjusted in accordance with certain parameters on the basis of control commands from a system of control electronics 1 connected to the valve 14 .
  • control electronics I is connected to a sensor 8 which measures the volume of water actually passing through, which is determined by the head of the high-pressure pump 7 with adjustable drive 24 , which can be set manually (e.g. via a potentiometer) or adjusted automatically.
  • the quantity of additive medium necessary for the desired mixing ratio (bentonite as a quantity in suspension) is fed in via a conveying device 6 which is connected to a so-called big bag 5 or other storage containers containing the bentonite stock, precise metering taking place via a drive 3 of the conveying device 6 which is connected via a setting member 2 to the system of control electronics 1 .
  • bentonite passes via a feed line 21 into the conveying device 6 , which conveys it to the high-pressure pump 7 in a quantity dependent on the speed of the drive 3 , the speed of revolution of the drive being transmitted to the system of control electronics I via a sensor 20 .
  • the system of control electronics I guarantees, via the setting member 2 , that the desired speed of rotation of the drive 3 is maintained.
  • the suspension medium passes downstream of the shut-off valve 14 on the low-pressure side of the high-pressure pump 7 into the service water and is conveyed together therewith by the high-pressure pump 7 into a high-pressure mixing section 15 , intensive mixing already taking place as a result of the pumping operation of the high-pressure pump 7 .
  • the mixing section 15 comprises a plurality of static or dynamic mixers operated in series or parallel, static mixers being preferred, as in these only the components to be mixed are moved.
  • the mixing is intensified by division, deflection and reforming of the media.
  • the spherical structure of the bentonite constituents is broken up by the high shear forces acting in the mixer. This results in a reduction of the swelling time, as the surface of the suspension medium at which the water molecules accumulate is increased.
  • a swelling section 16 which, depending on the embodiment, allows a longer or shorter swelling period of the drilling suspension.
  • the swelling section 16 may consist of an intermediate container or a coiled tube, or may also take the form of the section of the drilling pipe 10 via which the suspension is fed to the drilling o head 11 or the expansion tool 17 .
  • Further additives such as for example polymers or soda ash, may be added to the drilling suspension via the feed lines 18 , 19 , which are again fed in immediately upstream of the high-pressure pump 7 .
  • the service water may also be fed in via a storage tank 9 .
  • the suspension medium passes into the service water in a buffer container 23 .
  • the buffer container possesses a level switch (a, b) which switches the bentonite feed on and off, depending on whether the medium is above the upper mark a or below the lower mark b.
  • the buffer container 23 preferably takes the form of a narrow, vertically arranged pipe which prevents demixing of the service water/drilling suspension mixture before entry into the pump 7 .
  • the buffer container 23 further prevents the unintentional introduction of air into the high-pressure pump 7 .
  • the suspension medium is fed in on the high-pressure side of the high-pressure pump 7 .
  • the suspension medium passes into the service water in the region of the water jet nozzle 22 of the high-pressure pump, as a result of which intensive mixing is achieved.
  • the mixing situation can be influenced via the design of the water jet nozzle 22 .
  • the diameter of the water jet nozzle can be adjusted according to the flow volume, in order to ensure an intensive water jet at all times.
