so that transmission and separation of the transmission straight shaft 4b3 and the connecting shaft 4b7c are achieved, oil in an oil layer can be quickly pumped out due to negative pressure generated by the rotation of the hydraulic wheel 4b7e, and therefore the problem that in the middle and later stages of development, the pressure of the oil layer can be gradually reduced and is insufficient to drive the crude oil in the oil layer to the bottom of a well and lift the crude oil to the ground, the bottom end of an oil pipe fixed on an oil well cannot be in contact with the crude oil, and therefore natural gas or water needs to be injected into the oil layer to enable the crude oil to float upwards, the amount of natural gas or water injected into the oil layer is large, and the.
