杆式泵井况判别及优化分析

Analysis of discrimination and optimization of well condition by rod pump

杆式泵在缩短修井周期、保护油管丝扣方面效果显著,但是杆式泵座封面的存在增大了泵筒漏失量,而且座封面漏失、失效都将导致油井躺井。因此,在实际生产中如何利用示功图快速、准确的判断杆式泵在井筒的生产状况就显得尤为重要。

The rod pump can help to shorten the period of workover and protect the tubing thread.But the existence of the rod pump seat cover increase the threat of pump barrel leakage.Besides,loss and failure of the seat cover will lead to failed well. Therefore,it is very important to use the indicator diagram to judge the actual production status of rod pump in the pit shaft rapidly and accurately.
