Abstract
The invention belongs to the technical field of mechanical oil extraction process in an oil field development engineering and relates to a novel liquamatic blade type multiphase mixed pumping pump. The liquamatic blade type multiphase mixed pumping is characterized in that a liquamatic driving mode is adopted, ground power liquid pushes underground unit worm wheel stage rotators to rotate so as todrive a worm wheel shaft to rotate; a coupling drives a pump shaft to rotate, thereby realizing the rotation of an impeller of the pump shaft; and the oil extraction process is realized by the pressurization and the rectification of various stages of impellers and guide wheels. The liquamatic blade type multiphase mixed pumping pump has relatively-simple structural design, high driving efficiencyand favorable speed changing performance, can adapt to underground mixed pumping work station of oil wells with high air rate and can be widely applied to the underground mixed pumping process of oilextraction.
Description
Technical field
The present invention relates to a kind of down-hole oil gas device that polyblends, particularly a kind of Liquamatic blade type multiphase mixed pumping pump.
Background technique
Along with oil field development enters the middle and later periods, after being subjected to gas content to influence down-hole axial flow oil gas mixed pump that the less while can realize effectively that oil gas polyblends to occur, the research of its driving mode becomes focus, existing electricity drives with the ground surface driving mode and develops early, technology is comparative maturity also, but because the electricity mode of driving need be transported to the down-hole unit by a cable, be subjected to the down-hole temperatures involved, cause cable impaired easily; And ground drive motors need arrive the down-hole unit with transmission of power by transmission shaft, causes set structure relatively complicated on the one hand, and moment of torsion descends in the transmittance process on the other hand, has reduced capacity usage ratio; Electricity drives with ground surface driving and is subjected to cable and sucker rod structural limitations simultaneously, and the following pump degree of depth of mixed pump is superficial.
Summary of the invention
The present invention is to provide a kind of novel Liquamatic blade type multiphase mixed pumping pump, it can effectively overcome or avoid above-mentioned electricity drive with the ground surface driving technology in the shortcoming or the deficiency that exist, drive the multi-phase mixed pump work of blade type by the hydro powered mode.
Liquamatic blade type multiphase mixed pumping pump of the present invention is made up of the blade type of the turbine stage on top and the bottom pump stage that polyblends, the turbine stage rotor drives the turbine shaft rotation, pump shaft is connected transferring power with turbine shaft by coupling or screw thread short circuit, pump shaft drives the rotation of pump stage impeller, thrust bearing and seal arrangement are housed between turbine stage and pump stage, pass through flange plate or scyewed joint between turbine stage and the pump stage.Down-hole of the present invention unit is installed pattern has insertion fixed, and sleeve pipe is fixed, four kinds of parallel tubes free style and sleeve pipe free styles.
The present invention compared with prior art has following advantage:
1, cancellation sucker rod or drive motor, the turbine motor that changes by the down-hole drives the mixed pump unit, and structure is simple relatively, has improved the reliability of a whole set of unit when reducing manufacture cost.
2, the power of this turbines is that the impact to turbine is transformed in the down-hole by high voltage power liquid, transmission efficiency height, capacity usage ratio height.
3, have good gearshift performance, axial force balance structure, the downhole condition to complexity has good adaptability simultaneously.
4, the restriction of sucker rod and cable has been cancelled in this invention, and following pump depth ratio is bigger.

Embodiment
As shown in Figure 1, the Liquamatic blade type multiphase mixed pumping pump of this invention is made up of the turbine stage on top and the multi-phase mixed pump stage of blade type of bottom, turbine stage is mainly by turbine stator 1, turbine rotor 2, turbine shaft 3 and overcurrent ring 4 are formed, and the multi-phase mixed pump stage of blade type mainly contains guide wheel 7, and impeller 8 and pump shaft 9 are formed, between turbine stage and the multi-phase mixed pump stage of blade type thrust bearing and seal arrangement 5 are housed, turbine shaft 3 is connected by splined sleeve coupling 6 with pump shaft 9.
Power fluid comes out from the ground kinetic pump, pass through well-head valve, the center oil pipe enters the down-hole unit, flow to the lower end from the upper end of turbine stage, promoting turbine rotor 2 rotates, thereby driving turbine shaft 3 rotates, behind the lubricated thrust bearing of the exhaust power fluid of crossing, enter oil, the sleeve pipe annular space, the rotation of turbine shaft 3 drives pump shaft 9 rotations of the multi-phase mixed pump stage of blade type by the effect of splined sleeve coupling 6, be fixed on impellers at different levels 8 rotations on the pump shaft 9, to the supercharging that makes progress of liquid in the pump, and with in the suction port suction pump of the outer liquid of pump by the pump bottom, the gas-liquid two-phase of suction pump is flowed out mixed pump at last and is entered oil by impellers 8 at different levels and guide wheel 7 supercharging and rectification successively, the sleeve pipe annular space, return ground with exhaust power fluid, and deliver to above-ground storage tank by pipeline and some spreading pieces with mistake.The liquid flowing route of power fluid and extraction liquid as shown in Figure 2.
Claims (2)
1, a kind of Liquamatic blade type multiphase mixed pumping pump, form by turbine stage and the blade type pump stage that polyblends, it is characterized in that the blade type multi-phase mixed pump adopts the hydro powered mode, the ground power fluid comes out to promote down-hole unit turbine stage rotor rotation from the ground kinetic pump, thereby drive the rotation of turbine shaft, drive pump shaft by coupling or screw thread short circuit and rotate, thus the rotation of impeller on the realization pump shaft, by the supercharging of impellers at different levels and guide wheel and the oil recovery process of rectification realization mixed pump.
