Description
The present invention relates to provides the method for pressure energy, the heterogeneous fluid that be specially adapted to from oil well take out as the force feed machine to the multi-phase fluid gas mixture with single pump.This system also can handle the fluid that contains the small amount of solid particle, and this depends on the solid throughput that pump allows, and the present invention is best suited for the situation that requires height reliability under condition unattended and seldom maintenance.These situations can relate to the sea to be used down, and unmanned offshore platform, and the abominable occasion of land environment are perhaps seen the area of supply bottleneck from the logistics viewpoint.
The method and system of feasible in recent years pumping multi-phase gas-liquid mixture is summarized as follows states two classes:
A), only operate the liquid phase thing with a machine (pump), and another machinery (compressor) only is used for the gas phase thing based on the method and system that respectively is separated;
B) based on the method and system that uses multiphase pump, can directly handle multiphase mixture.
(A) type systematic need use two types machine, and one of them (compressor) is characterised in that it has suitable mechanical accuracy, but poor reliability.
(B) the class machine is still at the experimental stage at present.Also needing to carry out a large amount of work and experiment just can reach effectively and reliable industrial level.
The purpose of this invention is to provide a kind of pumping multi-phase gas-liquid mixture method of utilizing a conventional pump just can overcome above-mentioned prior art defective.
The characteristics of the method for pumping multi-phase gas-liquid mixture of the present invention are to use a pump as the force feed machine, and use two pumping containers at least, and this two container is alternately carried out intake function and compression and/or delivery functions.
Because therefore the inevitable liquid phase thing that only is used for of pump can be chosen from conventional pump, can select a centrifugal pump especially for use.
When only using two containers, they are always alternately carried out and suck and compression/delivery functions.
Using two during, an also practicable miscellaneous function with upper container.
This method discloses out two kinds of maneuvers.

(c) make that by more liquid is introduced described second container from described first container through described pump being compressed gas and compressed liquid leaves second container and enter and transport pipeline, it is identical with the amount of fluid that enters system in first container to leave the amount of fluid of described second container.
In the method, using under two situations with upper container, each container can play suction, auxiliary, compression/function of transportation successively; Or rise suck, compress/transport, booster action.
Second kind of operating method is only applicable to plural container, and these containers are alternately carried out and sucked function, compression/auxiliary function and transport function.
Above-mentioned second kind of operating method comprises the steps:
(a) multiphase mixture is imported under described intake line pressure first container of a full of liquid from a pressurization intake line, in described first container, multiphase mixture is separated into a gas phase and a liquid phase;
(b) in gas-liquid separation with described first container liquid and in first container isolated liquid deliver to a pump, by means of this pump with liquid pump into one in it abrim at second container that transports the gas under the pipeline pressure;
(c) make described second container interior at one the 3rd container of the described gas inflow of a part under intake line pressure that transports under the pipeline pressure, transport pipeline pressure up in described the 3rd container, reaching, simultaneously by with liquid from described first container pump into described second container and in described second container, keep transport pipeline pressure and
(d) by being introduced described second container from described first container by described pump, more liquid makes compressed gas and compressed liquid leave second container and enters the described container that transports that it is identical with the amount of fluid that enters system at first container to leave the amount of fluid of described second container.
In this operating method, each container plays suction successively, compression/auxiliary, the function of transporting.
Under the situation of using centrifugal pump, stable as far as possible for the serviceability that makes pump, it is necessary using (pressure or flow speed control) modulating valve.
Can understand the present invention better referring to Fig. 1,2,3, wherein:
Fig. 1 illustrates according to one embodiment of present invention,
Fig. 2 show according to another embodiment of the invention and
Fig. 3 shows according to still another embodiment of the invention.
The state of pumping container (1,2,3) is by the decision of the state of switch valve (4,5,6,7,8,9), and switch valve is handled by a special electronic logic control system.
Referring to Fig. 1, wherein container (1) is at its sucting stage, container (2) is in its associated phase, and container (3) is in its compression/transport the stage, in this case, heterogeneous fluid (10) enters the container (1) of full of liquid by valve (11), (and other valves 12,13,14,15,16 close), this container plays gas/liquid separation, enter centrifugal pump (17) and be somebody's turn to do " liquid piston " by valve (4), regulate or pressure regulator valve (18) and valve (9) are sent to container (3) (at first the gas under suction pressure) abrim then by flow velocity.Enter the gas in " liquid piston " compression container of container (3), make it reach the pressure that transports pipeline.At this moment, valve (16) is opened, gas is sent into certain amount of fluid then transported pipeline (19) earlier, this amount of liquid is identical with the amount of liquid that enters native system, when the liquid level in the container (1) reaches suitable minimum, the state of control logic line conversion switch valve.Container (1) changes secondary status (valve 4 cuts out) over to, and container (3) changes suction condition (valve 8 is opened, valve 9 semi-closures) over to, and container (2) changes compression/shipping situation (valve 7 is opened) over to.This program repeatedly repeats, the pump (17) so that continuous liquid stream is flowed through, and this pump is operated under the state of almost stable by means of modulating valve (18).Between " liquid piston " and heterogeneous fluid, do not need interval or detached body.
This system also can be according to the different operating program work, this program can become suck/compress-transport/auxiliary routine (for each container), to replace suck/assist/compressing-transporting program.
The another kind of structure of system shown in Figure 1 is described in Fig. 2.
Refer now to container (1) and be in its sucting stage, container (2) is in the stage of transporting, and container (3) is in the situation of compression/associated phase.
Heterogeneous fluid (10) enters the container (1) of full of liquid (by valve 11, other valves 12,13,14,15 and 16 cut out), this container plays the effect of gas/liquid separation and " liquid piston " enters centrifugal pump (17) by valve (4), modulating valve (20), (21) and (22) make the pressure that transports of pump keep constant, thereby guarantee the proper operation of pump.
Compression step is achieved in that a part of gas that will transport container (2) is transported to the container (3) that is in compression stage by modulating valve (21), transports pressure up to reaching in this container.
" liquid piston " is pumped into container (2) by valve (7), should " liquid piston " in this stage a part of pressurized gas be delivered to container (3) by valve (21), and the remaining part pressurized gas is equaled quantity to enter the identical liquid of native system amount of liquid then send into by valve (14) and transport pipeline (19) earlier.
When the liquid level in the container (1) reaches a suitable minimum, control logic line conversion switch valve state.Container (1) changes compression/secondary status (valve 4 and 11 cuts out) over to; Container (2) changes suction condition (valve 13 and 6 is opened, and valve 14 and 7 cuts out) over to; Container (3) changes its shipping situation over to.
Another kind of selectable structure is represented by the sketch among Fig. 3.
In the figure, increased a gas-liquid separator (23).
So just can only gas be sent into the upper inlet of pumping container, and liquid directly be sent into the suction port of centrifugal pump (17).
With regard to remaining part, the operation of structure shown in Figure 3 and shown in Figure 1 approximate.
Structure shown in Figure 3 has been given to separator (23) with the separation function of (gas/liquid) mutually of pumping container (1,2 and 3).
Another kind is applicable to that the possible practice of Fig. 1 and Fig. 3 is to use three modulating valve (each pumping container has a valve) setting of connecting with switch valve (5,7,9), to replace single modulating valve.
As can be seen, the pumping container can be got various forms (level, vertical container etc.), this will be according to this method scheme (the practiced function of same container) that adopts, and the characteristic of handled fluid is selected, for example referring to the schematic representation among Fig. 3, because the pumping container is not the form that can adopt vertical container simultaneously as the separator event of phase.
The quantity of pumping container can increase, and also can reduce (being reduced to two), under situation about reducing, needs to allow higher function nonuniformity.
