摘要
随着气田的开发和天然气的不断采出,地层压力逐渐降低,一些积液气井在压力恢复测试过程中出现压力上下波动的情况。基于这种情况,在详细讨论了引起压力波动异常现象的各种因素的基础上,重点对"积液倒灌"的影响进行了深入分析,明确了积液气井井口压力恢复异常原因,并提出解决该问题的技术思路和方法。
With the development of gas field and gas extraction,formation pressure decreases gradually,some fluid from gas wells in the process of pressure buildup test pressure fluctuating condition.Based on this situation,in the pressure fluctuation caused by abnormal phenomenon is discussed in detail various factors on the basis,focusing on the effect of the effusionintrusion carried on the thorough analysis,understanding the reason of the effusion gas well head pressure recovery exception,and put forward the technical ideas and methods to solve the problem.
