Split twin-well pumping unit

Abstract

The invention provides a split twin-well pumping unit which mainly solves the technical problems of the prior art that the structure is complicated, the maintenance is inconvenient, the using environment of twin-well oil pumping is limited, the oil well support position is difficult to adjust and the like. A power base of the split twin-well pumping unit comprises a motor, a speed reducer, a power belt compression roller and a braking device, wherein the motor is a permanent AC (alternating current) servo motor or a switch reluctance speed regulating motor; the power belt compression roller is provided with a locking component for locking one end of an A well belt and one end of a B well belt respectively; the tops of the A and B supports are provided with a counter weight roller and an oil pumping roller with an adjustable position in horizontal direction; one end of the A well belt and one end of the B well bet are connected and locked with respective corresponding locking components on the power belt compression roller; and the other end of the A well belt and the other end of the B well belt are connected with a corresponding A well beam hanger and a B well beam hanger by moving round the counter weight roller and the oil pumping roller. The split twin-well pumping unit provided by the invention is of a simple structure and can be quickly and conveniently adjusted according to the oil well position of and stroke.

Description

technical field [0001] The invention relates to a double-well pumping unit applied to mechanical oil recovery in oilfields to realize single-well or double-well pumping; in particular, it relates to a split-type double-well pumping unit whose drive part is placed on the ground; it can also be applied to Gas field extraction. Background technique [0002] The oil field is not only a large energy provider, but also a large energy consumer. As the most important energy-consuming equipment in the oil field, the pumping unit not only bears the heavy responsibility of producing crude oil, but also consumes a lot of electric energy. In order to maintain the economical operation of the pumping unit, reduce The waste of electric energy, a lot of manpower and material resources are invested in the maintenance and energy saving measures of the pumping unit every year. With the extension of the oilfield development period, the formation energy is gradually depleted, and it is difficult ...
