摘要
塔里木油田克深8号气藏地质条件复杂,地层压力敏感性强,在压井时不能采取常规的压井方法进行压井作业。以KeS8-A井为例,介绍了在油套连通、生产套管存在漏点、环空压力超限的情况下,首先考虑井控风险,结合压井液类型、压井液密度、压井方法等,采用非常规压井方法的综合应用手段,有效地控制了风险,达到了压井目的。
The geological conditions of the Kam No.8 gas reservoir in the Tarim oilfield are complex,whose formation pressure sensitivity is strong,and the traditional way of killing well is not used.Taking KeS8-well as an example,on condition of being connected of tubing and case,having leakage point of the production casing,exceeding the limit for the annulus pressure,it is introduced that well control risk is considered firstly,and combined with the type of well killing fluid,well killing fluid density,well killing method,etc.,using unconventional means of integrated application of well killing method has been utilized to control the risks effectively,achieving the purpose of it.
