非自喷井螺杆泵求产测试评价技术

Testing and evaluating technology of screw pump for unflowing wells

非自喷井间歇求产是一个复杂的求产过程,利用数值网格分析及全压力历史拟合方法,解决了间歇求产井地层参数求解问题。为了获取螺杆泵求产时的液面恢复数据,在螺杆泵底部外挂电子压力计,得到了螺杆泵求产过程中的地层压力分布及井底压力,优化了螺杆泵测试工艺。

Intermittent production of unflowing well is a complex intermission producing process.Numerical grid analysis and full pressure history fitting method are used to solve the problem of formation parameters in intermittent unflowing wells.In order to get the data of liquid level recovery during the production of screw pumps,an electronic pressure gauge is mounted on the bottom of the screw pump,the formation pressure distribution and bottom hole pressure during screw pump production are obtained,optimizing the testing process of screw pump.
