井漏是钻井施工过程中经常出现的问题之一,井漏的出现除了会给钻井施工工程造成如延长钻井时间、井喷以及井塌等问题以外,还可能会造成产层的严重破坏。因此,及时找出井漏原因并进行有效解决就十分重要。本文对钻井施工过程中井漏的原因及解决对策进行了重点分析。 Lost circulation is one of the most frequently encountered problems in drilling construction. In addition to problems such as prolonging drilling time, blowout and well collapse, the occurrence of leakage can cause serious damage to the pay zone. Therefore, it is very important to find the cause of leakage in time and solve it effectively. This paper focuses on the reasons of well leakage during drilling construction and the countermeasures.
