中古70井高压气层溢流压井处置分析
|
摘要
钻井过程中钻遇异常高压地层是发生溢流的主要原因之一,本井在奥陶系鹰山组四段钻遇高压气层发生溢流,经过压回法压井成功,开井后活动钻具正常,溢流事件得到成功处置。本文详细分析了本井高压气层溢流的原因和经验教训,对以后发生类似的高压气层溢流井处理具有参考意义。
Drilling abnormally high pressure formation is one of the main causes of overflowing,this well in Ordovician Ying Shan group 4 th period drilling high-pressure gas layer overflow occurs,after back pressure method killing success,and open the well drilling activities normal,this overflow events be successful treatment.This paper analyzes the causes and lessons of the high-pressure gas layer overflow,after the occurrence of a similar high-pressure gas layer having a relief well process reference value.
