多井抽油中心系统及其特性分析
Multi-well pumping units system and its features analysis
摘要
Abstract
In the light of the problems of multi-transmission segments, poor movement performance, reactive payload of sucker rod, large fluctuating range of payload, negative power and torque of beam pumping units, a method of fluctuating payload multi-phase homogeneous outputting was designed, and a multi-well integrated pumping units system was researched. The system kinematic analysis equations were founded, and the formulas about polished rod displacement, velocity, acceleration, reducer output torque and electrical power were derived and comparative analyzed with beam pumping units. The results show that, the power performance of multi-well pumping units is better than that of beam pumping units, the maximum torque decreases , and the fluctuating payload becomes homogeneous and completely positive. Installed power is decreased and working condition is improved. As working in even number wells, necessary drive decreases by self-balancing of payload. The pumping units need to add balance piece as working in odd number wells. The life of flexible power-transmission products should be considered in design process. The field tests have a good effect and it's a new method of saving energy by driving multi-well with single motor and positive torque.关键词
