Definitions

  • the present invention relates to methods and installations for circulating fluids by pumping. More particularly, the invention relates to methods and installations for pumping fluids composed of at least one liquid phase and at least one gaseous phase, the latter making pumping very difficult.
  • the ejector thus formed applies an initial pressure increase to the fluid in the well.
  • the liquid should therefore leave the turbine while also having a certain pressure.
  • the energy of the liquid is not optimally used in the turbine, since part of this energy is necessary for a downstream operation.
  • this has the disadvantage that the pump must be designed for a large flow rate and therefore requires a large power .
  • the liquid serves as the supply fluid for the turbine of the turbomachine, supplying the energy necessary for the operation of the pump.
  • Part of the liquid also serves to decrease the gas content of the fluid and thus make it acceptable so that the mixture of fluid and liquid can be pumped. Since as little expanded turbid liquid is passed through the pump as possible, it requires as little power as possible.
  • the liquid is completely expanded in the turbine and neither is it allowed kinetic energy.
  • the turbine thus operates under the best conditions.
  • the gas content of the fluid is detected and the proportion of the liquid mixed with the fluid is modified as a function of the gas content detected.
  • the ratio between the quantity of turbinated liquid entering the mixture and that which is discharged can vary between 0 and 0.5.
  • the flow rate of turbinated liquid mixed with the fluid which represents from 0 to 2 parts by volume per 1 part of the fluid, is equal to the flow rate of liquid, separated in the form of a first stream and representing from 25% to 65% of the volume of the mixture, which leaves the pump.
  • the invention also relates to a pumping installation comprising a fluid source and a turbomachine comprising a pump, having an inlet and an outlet, and a turbine which is set on the same shaft as the pump and which has an inlet and an outlet, the outlet of the turbine opening into a conduit putting the source in communication with the pump.
  • the installation is characterized by a rejection or return duct communicating with the outlet of the turbine and by a device making it possible to regulate the quantities of liquid coming from the outlet of the turbine which go into the rejection or return duct and into the conduit putting the source in communication with the pump.
  • the installation comprises a detector of the gas content of the fluid and the device making it possible to adjust the quantities of liquid is controlled by the detector via a control line as a function of the levels detected.
  • the installation comprises an apparatus for separating a fluid consisting of a gas phase and a liquid phase into a first stream richer in the liquid phase than the fluid and into a second stream, the apparatus being provided an input which communicates with the output of the pump and two outputs, one of which for the first current communicates with the input of the turbine.
  • the pump is such that the curve representing the value of the curvature along the skeleton of the profile of a blade as a function of the curvilinear absence along this skeleton, has a slope whose value gradually increases from the edge of attack towards the trailing edge of the blade, as described in French patent 7,536,774; the pump advantageously has the other characteristics defined in this patent, but the pump can have any other hydraulic specially adapted to two-phase flows.
  • Fluid composed of a liquid phase and a gaseous phase comes from a source 1 through a conduit 2.
  • a conduit 3 coming from the outlet 4 of a turbine 5 of a turbomachine.
  • This machine essentially comprises the turbine having the outlet 4 and an inlet 6 and a pump 7 having an inlet 8 and an outlet 9 and wedged on the same shaft 10 as the turbine 5.
  • a detailed description of this turbomachine can be found in French patent 7823250 .
  • a device 18 making it possible to adjust the quantities of liquid which go respectively to the conduit 11 and to a rejection conduit 17.
  • the device 18 is controlled via a line 20 by a detector 19 which detects the gas contents of the fluid passing through line 2.
  • the mixture of fluid and liquid is sent under a pressure of between 10 and 100 bar, via a conduit 11, to the inlet 8 of the pump 7.
  • the latter discharges it through the outlet 9 and through a conduit 12 into a separation apparatus 13, where the mixture, optionally after settling or centrifugation of the solid materials, is separated into a first stream going through the conduit 14, with compression in a pump 16 at a pressure between 20 and 250 bar, at the inlet 6 of the turbine 5 and in a second stream discharged through a conduit 15.
  • the gas content of the first stream is less than 5% by volume.
  • 60 m 3 / h of gas-free oil are sent to the turbine under a pressure of 100 bar.
  • the turbomachine rotates at 6000 rpm.
  • the pressure relief height in the turbine is 800 m.
  • the expanded oil is mixed with 60 m 3 / h of crude oil having a GLR of 10.
  • GLR represents the ratio of the volume of gas to the volume of liquid.
  • the head of the pump is 150 m. Despite its high GLR, the crude can thus be pumped without difficulty.
