Environment-friendly oil pumping device for oil and gas field exploitation

Abstract

The invention discloses an environment-friendly oil pumping device for oil and gas field exploitation. The environment-friendly oil pumping device comprises F-type brackets, a motor, an oil storage tank, an oil well pump, an oil production rod and a casing pipe, wherein a first mounting sleeve and a second mounting sleeve are mounted on the oil production rod respectively; the multiple F-type brackets are mounted on the outer sides of the first mounting sleeve and the second mounting sleeve; a driven gear is mounted and fixed on the oil production rod between the first mounting sleeve and thesecond mounting sleeve and in meshing connection with a driving gear mounted on an output shaft of the motor; the oil storage tank is fixed at the tops of the F-type brackets; the oil well pump communicated with the inner cavity of the oil storage tank is arranged at the top of the oil storage tank; the lower part of the oil production rod is in sleeve joint with the casing pipe; the lower end ofthe oil production rod is connected with an expansible bellows in the casing pipe; a spiral plate is mounted on the outer side of the casing pipe; an oil inlet hole is formed in the casing pipe. The environment-friendly oil pumping device is novel in structure and convenient to operate, manpower invested for oil production is reduced greatly, oil yield is increased, and quality of produced oil isimproved.

Description

technical field [0001] The invention relates to the field of oil and gas field exploitation equipment, in particular to an environment-friendly oil pumping device for oil and gas field exploitation. Background technique [0002] Most of the oil wells in eastern China have multi-layer heterogeneous structures, and there are serious problems of interlayer interference when using the combined production method to recover oil. For example, there are large-scale superimposed oil-bearing areas of Sartu, Putaohua, Fuyu, Yangdachengzi and Heidimiao oil layers in the periphery of Daqing oil well. The reserve abundance of these oil layers is low, and the existing chemical oil recovery technology will cause pollution. The fracturing, acidizing and other technologies use a lot of equipment, many construction workers, complex processes, and the extracted oil has many impurities, resulting in low oil production. Therefore, in view of this current situation, it is urgent to develop an env...
