Research on the Reliability Digital Simulation of Rod Pumping System

利用可修系统可靠性分析理论,提出在役有杆泵抽油系统工作可靠性数字仿真模型。在对现场数据收集、整理的基础上,推断各子系统寿命和维修时间的统计模型,运用Monte Carlo法通过抽样模拟对系统可靠性和维修性进行数字仿真,实现对系统可靠性的定量评价。

By using the reliability analysis theory of the maintainable system, this paper sets up the digital simulation model to the reliability of the rod pumping system in service. On the basis of the data of spot collected and trimmed, we infer statistical model of lifetime and maintainable time of each subsystem, enforce digital simulation to reliability and maintainability of system by the sample simulation which utilizes Mont Carlo method, and realize quantitative evaluation to the reliability of system in the end.
