A beam pumping unit with composite balance for oil drilling

Abstract

The invention relates to a beam pumping unit with composite balance for oil drilling, which includes an operating table, a beam strut and a balance connecting plate, the bottom of the operating table is fixed with a support base plate, and the top of the operating table is fixed by screws A triangular bracket is connected, a connecting platform is arranged on the top of the triangular bracket, and a fastening shell is connected to the top of the connecting platform, the beam strut is arranged inside the connecting platform, and a hydraulic rod is arranged at the right end of the connecting platform , the right end of the beam strut is connected with a donkey head main body, and a rope hanger is installed at the bottom end of the donkey head main body. The beneficial effects of the present invention are: the oil drill adopts a compound balanced beam pumping unit through the movable setting of the balance connecting plate, when the balance connecting plate is set at the left end of the beam strut, it is set on the floating beam combined with the main body of the donkey head. The right end of the beam strut, according to the characteristics of the lever principle, the beam strut works in an environment of left and right compound balance to ensure the overall balance of the device.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling and production, in particular to a beam pumping unit which adopts compound balance for petroleum drilling. Background technique [0002] With the development of science and technology and the progress of the social era, the technology of oil extraction is becoming more and more mature. During the mining process, pumping units are mostly used for operation. According to whether there is a beam, it can be divided into beam pumping unit and beamless pumping unit. Pumping unit, beam pumping unit, also known as beam pumping unit, beam pumping unit with crank rod balance, refers to a pumping unit that contains a beam, reverses direction through a connecting rod mechanism, and balances the weight of the crank rod The oil pump, commonly known as the kowtow machine, is a rod-type oil production equipment from the oil production method (it can be divided into two types from the oil production met...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of oil drill that adopts the beam pumping unit of composite balance, to solve the existing beam pumping unit proposed in the above-mentioned background technology when the oil is drilled and produced, due to the beam The overall balance cannot be guaranteed, which will affect the balance of the entire oil drilling and production structure. When working in an unbalanced environment, oil is extremely prone to spillage, resulting in a waste of resources.
