摘要
塔河油田主力油藏溶洞、裂缝比较发育,安全窗口很小,溢漏频繁发生、节流压井成功率低,通过对目前油田常用各压井方法的比较、溢流机理研究分析,优选出适合该油田的压井方法,认为压回法适合该油田的井控压井,并结合现场实践和理论计算总结出了压回法的具体压井技术。
The success rate of choke and kill system is low and overflow leakage occur frequently due to developed vugs and fractures in the main reservoir of Tahe oilfield, so that the security window is small. By comparing the commonly used pressure killing methods in oilfields, research the mechanism of overflow leakage,it is founded that the backpressure method is suitable for the oil field, and combined with field practice and theoretical calculation the specific well killing technique is summed up.
