Simulation Research On Double Horseheads Beam Pumping Unit

In the process of oilfield production,oil pumping unit is in the dominant and nowdaysone of the most widely applied pumping equipment is the conventional beam pumping unit,ithas the advantages of the conventional beam pumping unit,such as firm structure,reliableworking station,easy to maintenance,but also overall there the problem of low efficiency.Tomeet the hair oil saving and the requirement of sustainable development, improving theefficiency of suck rod pumping systems,saving energy and reducing consump-tion hasbecome an important research topic oil field. With the deepening of our oil develop-ment, inorder to increase oil production, Started playing interspaced well, and thus appeared the firstinterspaced well and secondary interspaced well, and three interspaced well,making wellspace getting closer, For an objective beam pumping unit with a drive two oil production ofthe well provide the conditions.This paper mainly analyses conventional swim double-horse head beam type doublewells pumping unit for research object, analyses the main the structure and the workingprinciple, this paper introduces the structure characteristics of the pumping unit different fromany conventional.Combining general theory of the conventional beam pumping unit of thekinematics and dynamics analysis. Obtain the two corresponding analytical equation formotion equations and the gearbox output shaft torque calculation formula. On the double wellthe balance of the pumping unit principle and energy conservation for analysis, that balanceeffect is good, saving energy and reducing consumption theory basis. Based on SolidWorkssoftware established SCYJ8-3-48HB type swim double-horse head beam type double wellspumping the virtual prototyping model, The simulation research, get under different workingconditions, suspend sport characteristics. Using ansys software of scaffold calculated by finiteelement analysis, find out the maximum stress position and deformation position, Thestiffness and strength of checking result meet use demand. The Hyperworks software to swimexpansion in different spacing beam, working conditions is analyzed and calculated, andobtains the corresponding working downstream of the beam stress distribution, the displace-ment map deformation figure, analyzes the maximum stress position and maximum deforma-tion position, have to travel beam meet stiffness and strength use requirement. Through thispaper research to establish energy saving oilfield has very important practical significance,and the promotion of the oilfield energy saving pumping unit have certain positive role.
