Description
Technical field
The present invention relates to the oil recovery of a kind of oil field and use mechanical device, belong to oil recovery machiner technical research field.
Background technology
At present, mechanical oil recovery is the main oil production method on the oil field, and wherein beam pumping unit is occupied an leading position.But only about 25%, energy consumption is high for the beam pumping unit system average efficiency.Simultaneously, the ripe day by day of oil exploration and drilling technology makes cluster well exploitation become the development trend in oil field, more than 800 of the existing cluster well groups of China, more than 3000 mouthful of well, more than 500 mouthful of annual newly-increased cluster well.Along with being on the increase of ocean oil well, land infill well and cluster well; If such oil well is continued to adopt the mining type of a machine one well; Not only can cause waste of electric energy; And the also corresponding increase of mining equipment cost, so the begin one's study oil production method of a machine twin-well or the many wells of a machine of researcher.Wherein the advantage of a machine twin-well is to make full use of the close characteristics of Liang Koujing, with an oil pumper two mouthfuls of wells is pumped simultaneously, and the mutual balance of the load of two mouthfuls of wells can reduce energy consumption, the material consumption of oil pumping system, improves oil pumping system efficient.Developed improved twin-well oil-pumping machine on the beam pumping unit basis at present; But the type twin-well oil-pumping machine is owing to operating principle causes efficient still can not improve near beam pumping unit; And restricted aspect the increase stroke, therefore do not obtain scale and use.
Summary of the invention
For adapting to the needs of new DP technology, practice thrift equipment cost, improve production efficiency, cut down the consumption of energy, realize high-efficiency mining to cluster well, invented a kind of new pumping unit---the direct driving motor twin-well oil-pumping machine.Design concept of the present invention is simplified, and promoting the use of cluster well on the oil field suits.
The present invention for the technical scheme that problem adopted that solution proposes is: the direct driving motor twin-well oil-pumping machine is made up of magneto, shaft coupling, day wheel assembly, belt assembly, guide wheel assembly, expanding pulley assembly, truss assembly, ballast box; The output shaft that it is characterized in that magneto directly is connected with shaft coupling with a day wheel assembly, and shaft coupling is the flange spline coupling; The guide wheel assembly is installed in the side of truss assembly to the main shaft mouth, and the expanding pulley assembly is installed in the side of truss assembly to the service shaft mouth; Belt assembly core component is two narrow belts and two wide belts; One end of two narrow belts is walked around the guide wheel assembly together with an end of two wide belts and is connected with main shaft mouth polished rod eye; The other end of two narrow belts is walked around day wheel assembly and is connected with ballast box, and the other end of two wide belts walks around day wheel assembly and the expanding pulley assembly is connected with service shaft mouth polished rod eye; The expanding pulley assembly is made up of fixed structure and slide construction, has pin-and-hole on the fixed structure, and alignment pin is arranged on the slide construction, through realizing stretching out and regaining of expanding pulley cooperating of diverse location between pin-and-hole and the bearing pin.
The invention has the beneficial effects as follows: realized the twin-well oil pumping, and can be through regulating the expanding pulley assembly to adapt to the oil well of different well spacings; Saved deceleration device and changement, improved efficient, compact integral structure, weight saving; Realize long stroke, helped increasing field output.
