Abstract
本发明涉及采油工程领域,具体涉及一种抽油机电功图转示功图摩擦力矩优化方法。本发明通过传感器获取数据,根据数据和曲柄、连杆、游梁的受力,通过曲柄、连杆、游梁受力平衡方程得到计入摩擦的摩擦力矩和驱动力矩,反复迭代得到优化后的摩擦力矩和驱动力矩,构建电功图并转换为示功图,对抽油机工作状态进行实时监测。本发明弥补了传统方法因忽略摩擦导致的转换功图精度低的问题,提高了功图转换精度,提高基于转换功图的油井诊断、计产准确性;通过对传统电功图转示功图方法过程的优化和改进,有效提高功图转换的准确性和时效性,从而逐步实现示功图的间接测量方式,大幅降低油井工况诊断和计量成本,推动基于电参数的油田低成本物联网建设
