| 摘 要： | 针对油井有杆抽油系统无法实现产量连续监测的问题，提出了基于悬点示功图油井产量动态测量方法：首先，基于悬点示功图建立泵示功图模型，然后根据泵示功图计算泵有效冲程，最后动态计算油井实时产量．应用该方法对两口油井的产液量进行了计算，相对误差分别为5．93％和6．87％，研究结果表明，该方法计算较为准确，可以为油井产量动态监测提供参考．

| Abstract: | Aiming at the problem that oil well sucker rod pumping system can＇t realize the continuous monito- ring of production, a method of dynamic production measurement that based on suspension point indicator dia- gram is proposed. First of all, a pump indicator diagram model is established based on the suspension point indicator diagram; then the pump effective stroke is calculated according to the pump indicator diagram; final- ly, the well＇s real-time production is calculated dynanically. This method is used to calculate two oil wells＂ produced fluid volume; the relative errors are 5. 93% and 6.87% respectively. The results show that this method is more accurate, so as to provide reference for oil well＇s production dynamic monitoring. |
