New Tower Type The Motor Commutation Pumping Unit Developed

Jidong Oilfield order to achieve the CNOOC land mining need to focus on thedevelopment of an artificial island, with the wellhead slot batch drilling technology by thisfeature, so that it will have strict requirements on the pumping unit and try to compactDimensions, job security, convenient, and reliable. Jidong Oilfield active duty pumping unitis about more than1100units, the vast majority are purchased considerable annualmaintenance and overhaul costs for the oilfield cost savings, develop long-stroke, low stroke,the small size of the energy-saving pumping unit, meet me oilfield needs to become animportant technology innovation.This project is to expand the basis of the above.Detailed comparison on the basis of the main types of characteristics of of JidongOilfield run the pumping unit and the new unit at home and abroad, as well as the advantagesand disadvantages of, determine the research and development of a new unit for the bracketto steel towertransmission mechanism through reducer, rollers, sheaves, flexible broadband,wire rope, led light pole under reciprocating motor powered. It requires a small footprint, andadjusting the stroke, Chong times convenient, low maintenance costs, energy-saving, suitablefor windy conditions.According to the basic theory and the demand for oil field pumping unit to determine thedesign of the pumping unit rod load, and to establish a theoretical indicator diagram,reference beam pumping standards to determine the new tower type motorcommutationmodels and basic parameters of the pumping unit. Through the recent years ofno swim deceleration of beam pumping unit and transmission mechanism analysis, change tothe system, balanced way, supporting way of contrast, the new tower type motorcommutation pumping unit commutation balance, deceleration mechanism, conveyor type bracket structure, Tianlun structure and gave way to determine the structure of the overallmachine.Check Calculation according to the selected new tower type motor commutationpumping unit load, the strength of the key components is given the key components tosimplify the mechanical model and by trying, according to the selected safety factor,demanda state of stress, and test the correctness of the calculation, and calculation resultsmeet the design and use requirements.Finally, the new tower type motor commutation pumping unit type test test methods andtest projects and acceptance criteria, concluded. And field applications track targetedrectification of problems are identified.The field application shows that: this new tower type motor commutation pumping unit,small size, adaptability, easy parameter adjustment features to meet the requirements ofJidong Oilfield applications.
