[0002] As oilfield development enters the middle and later stages, after the emergence of downhole axial flow oil-gas mixed pumps that are less affected by gas content and can effectively realize oil-gas mixed pumping, the research on its driving method has become a hot spot. The existing electric drive and ground drive The method developed earlier and the technology is relatively mature, but because the electric drive method needs to be transmitted to the underground unit through a cable, the cable is easily damaged due to the high temperature in the underground; while the ground drive motor needs to transmit power to the underground unit through the transmission shaft. On the one hand, the structure of the unit is relatively complicated; on the other hand, the torque decreases during the transmission process, which reduces the energy utilization rate; at the same time, the electric drive and ground drive are limited by the cable and sucker rod structure, and the pumping depth of the mixed pumping pump is relatively shallow

Embodiment Construction
[0013] Such as figure 1 As shown, the hydraulically driven vane-type multi-phase mixed pump of this invention is composed of an upper turbine stage and a lower vane-type multi-phase mixed pump stage. The turbine stage is mainly composed of a turbine stator 1, a turbine rotor 2, and a turbine shaft 3 Composed of the flow ring 4, the vane-type multi-phase mixed pump stage mainly consists of a guide wheel 7, an impeller 8 and a pump shaft 9, and a thrust bearing and a seal are installed between the turbine stage and the vane-type multi-phase mixed pump stage The unit 5 , the turbine shaft 3 and the pump shaft 9 are connected by a splined sleeve coupling 6 .
[0014] The power fluid comes out of the surface power pump, enters the downhole unit through the wellhead valve and the central oil pipe, flows from the upper end of the turbine stage to the lower end, and drives the turbine rotor 2 to rotate, thereby driving the turbine shaft 3 to rotate, and the used waste power fluid lubr...

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.
