潜油电泵井试井工艺及分析方法探讨

Approaching about Well Testing Tech and Analysis Method in Submersible Electric Pump Well.

探讨了利用潜油电泵下端连接的压力计、潜油电缆、潜油电泵变频驱动系统进行试井分析的可行性。通过潜油电泵井下现有的在线直读式压力测试装置,通过变频驱动系统改变油井产量,同时记录油井的压力变化,利用文中提供的试井分析方法求取油藏的地层参数及地层压力。利用该方法可及时掌握油井的生产动态,采取合理增产措施,制定合理的工作制度,以达到最佳开发效果。通过多井次的现场实例证实了该方法工艺上可行、解释方法准确有效。

Feasibility of using gauge, submersible electric cable and system of submersible electric pump variable frequency driving connected under submersible electric pump to analyze well testing is discussed. By means of submersible electric pump having device about direct reading pressure testing down hole, and changing production of oil well by system of variable frequency driving, and recording pressure variation in oil well on time, reservoir parameters and formation pressure are gained by method of well testing analysis. Using this method, it can promptly possess to production performance of oil well, take reasonable stimulation, and lay down reasonable working system to get the best development effectiveness. Field examples in many wells prove that this method is feasible in tech and interpretation method is accurate and effective.
