Definitions

  • the present invention relates to a device or arrangement for control of the fluid flow in particular in connection with production of oil and gas from geological formations below the surface of the earth.
  • chokes When producing oil and gas from reservoirs below the earth's surface it is usually required to control the flow of fluid related to such production by using one or more chokes that may restrict or open the flow through area of the respective choke to reduce or increase the produced fluid flow.
  • the chokes may be provided on the production line from each well, from a common production string prior to installed separation equipment or as a combination of such provisions.
  • a commonly known type of choke used for this purpose may be of the cage choke type (as shown in Fig. 1 attached hereto).
  • a major disadvantage with the known types of chokes is that the pressure is reduced by increasing the velocity of the fluid flow thereby intermixing the different phases, oil, gas and water, of the fluid, making it more difficult to separate.
  • Another disadvantage is that conventional choke does not provide constant quantity of fluid flow through the choke, which in turn does not contribute to the damping of fluid flow disturbances such as liquid slugging which can cause severe problems in the downstream process equipment.
  • the present invention is provided a solution for the control of the fluid flow in connection with the production oil and gas where the intermixing of the phases of the fluid is vastly reduced or eliminated.
  • the solution further provides fluid flow rate control, fluid slug damping, improved separation and process control.
  • the pressure may easily be controlled, increased or lowered, and with low well head pressure (below separator pressure, but above atmospheric pressure) the need for gas lift is reduced and well tail production may be prolonged as the invention may be used as a pump device.
  • the invention is characterized by the features as defined in the attached independent claim 1.
  • Fig. 1 shows a traditional choke used in oil and gas operations, partly in cross section
  • Fig. 2 shows a principal sketch of a production arrangement for oil and gas from different wells where the invention according to the present invention is included.
  • Fig. 3 shows an example of a production choke according to the present invention.
  • Fig. 1 shows a traditional choke used in oil and gas operations, partly in cross section.
  • the choke is in the shown example a cage valve choke which, depending on required or desired pressure, enables restriction or opening of the flow area of the choke to reduce or increase the flow and thereby reduce or increase the pressure down-streams of the choke when being provided in an oil/gas fluid flow line.
  • a major disadvantage with the known types of chokes is that the pressure is reduced by increasing the velocity of the fluid flow thereby intermixing the different phases, oil, gas and water, of the produced fluid, making it more difficult to separate.
  • Another disadvantage is that conventional choke does not provide constant quantity of fluid flow through the choke, which in turn does not contribute to the damping of fluid flow disturbances such as liquid slugging.
  • Fig. 2 shows a principal sketch of a production arrangement for oil and gas including four wells 1 each being provided with a choke 2 according to the invention, for instance in conjunction with a Christmas tree on the sea floor, and further being interconnected by a connection line 4 to a production line or riser 3.
  • the production line or riser 3 is in turn connected to a separator 5 on the sea floor or on a platform etc., depending on the place of production.
  • the process equipment may be provided sub-sea or top-side, or a combination of such provisions, or even possibly on-shore.
  • the major inventive feature of the invention is the provision (use) of a volumetric motor/pump as a choke to reduce or increase the pressure of the fluid arriving from the well or wells.
  • a volumetric motor/pump as a choke to reduce or increase the pressure of the fluid arriving from the well or wells.
  • Such pressure reduction is normally required to obtain the desired process pressure downstream of the wells, but reducing the pressure will as well improve separation of the fluid as gas being present in the well fluid is released and increases flotation of oil droplets in the water being present in the well fluid.
  • a volumetric motor/pump as a choke according to the invention the intermixing of the phases of the fluid is vastly reduced or eliminated.
  • the solution according to the invention further provides fluid flow rate control, fluid slug damping, improved separation and optimal process control.
  • the choke according to the invention is functioning as a volumetric motor when being used to reduce pressure.
  • the energy generated when used as motor may conveniently be captured in a mechanical break system or generated to hydraulic or electrical energy being used in the downstream fluid process system (not further shown or described).
  • the pressure initially is too high and needs to be reduced to normal downstream process production pressures.
  • the choke according to the invention may be used as a pump to lower the suction pressure thereby enhancing production.
  • the present invention may be used both as a motor to reduce production as well as a pump to enhance production prolonging the lifetime of a well.
  • the fluid from the wells is separated in the separator 5 into gas that is evacuated through the gas evacuation pipeline 6, oil that is drained from the separator through a drainage pipeline 7, and water through a drainage pipeline 8.
  • Water from the separator 5 may be further separated in a second water separator 9 downstream of the well fluid separator 5, and oil may be further separated in a down stream separator 15, respectively further separating the water and oil to cleaner components of water, oil and gas, components 12, 13, 14, 16, 17, 18 respectively.
  • displacement motor/pumps 10, 11 according to the invention is in addition provided between the two separators 5, 9, respectively 5, 15.
  • the device according to the present invention may be used both as an upstream choke 2 and as a downstream flow rate control device, 10,11.
  • the motor/pump according to the invention may be a displacement motor/pump of the screw type (single or twin), radial wing type, gear pump, piston/cylinder pump or a lobe pump as depicted in Fig. 3, showing the pump as such in perspective view as well as a functional sequence 1 - 4 in cross section .
  • the choke according to the invention may be used in "green-field" oil installations where new production is enhanced, but may as well be used to replace traditional well head chokes on existing installations in situations where there are problems with slugging, low pressure or separation.
