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 of high viscosity, for example heavy crude oils which are viscous and the pumping of which is very difficult with centrifugal hydraulics.
- the process according to the invention consists in sending liquid, of lower viscosity than the fluid and miscible with it, under pressure, to the inlet of the turbine of a turbomachine comprising a pump, having an inlet and an outlet, and a turbine which has an inlet and an outlet separate from those of the pump and which is wedged on the same shaft as the pump, mixing with the fluid part of the expanded liquid which leaves the turbine, and sucking the mixture of the liquid and fluid through the inlet of the pump.
- the liquid thus serves as the supply fluid for the turbine of the tubomachine providing the energy necessary for the operation of the pump.
- the liquid also serves to reduce the viscosity of the fluid and thus make it acceptable so that the mixture of fluid and liquid can be pumped by centrifugal hydraulics.
- the method is particularly useful in the case of a borehole, where the liquid must be sent anyway to the bottom of the borehole where the turbomachine is located, it is immediately accessible there, without the need for a pipe. special to bring him there.
- the volume flow rate of the liquid sent to the inlet of the turbine represents from 0.5 to 3 times the volume flow rate of the fluid to be pumped. It is advantageous that the volume flow rate of the liquid mixed with the fluid to be pumped represents from 0.1 to 0.5 times the volume flow rate of the fluid to be pumped.
- the liquid should have a low viscosity, be miscible with the fluid by reducing the viscosity of the mixture, contain little gas and preferably does not react on the fluid.
- a liquid having a viscosity of 1 to 10 centistokes is used, by having a mixture whose viscosity is less than 30 centistokes.
- the method consists in separating the fluid which leaves the pump, in a first liquid stream and in the second stream, in compressing the first stream, in compressing the part of the expanded liquid which leaves the turbine and which does not is not mixed with the fluid and combine it with the first compressed current to send everything to the turbine inlet.
- the invention also relates to a pumping installation, comprising a liquid source and a turbomachine comprising a pump having an inlet and an outlet, and a turbine which is stalled on the same shaft as the pump and which has an inlet and an outlet, characterized in that the outlet of the turbine opens into a conduit putting the source in communication with the pump and the installation comprises apparatus for separating a fluid into a first stream less viscous and a second stream more viscous, the apparatus being provided with an inlet which communicates with the outlet of the pump, and two outlets one of which for the first stream communicates with the inlet of the turbine and there is provided a conduit communicating the outlet of the turbine and the outlet of the apparatus intended for the first stream, a compression pump being mounted on this conduit.
- Fluid of high viscosity leaves a source 1 through a conduit 2.
- a conduit 2 opens 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 a 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.
- the mixture of viscous fluid and less viscous liquid is sent under a pressure of between 10 and 150 bar, via a conduit 11 at the inlet 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 300 bar, at the inlet 6 of the turbine 5 and in a second stream discharged through a pipe 15.
- the additional liquid which leaves the turbine and which is not sent to the inlet of the pump is returned by a pipe 17, passing through a pump 18 which puts it under a pressure of between 20 and 300 bar, to a conduit 19 which joins the conduit leaving the pump 16 and going at the turbine inlet.
