摘要
2020年,四川盆地川南深层页岩气L203井区进入大规模勘探开发,由于同一个裸眼段“喷漏同存”,多口井发生“漏转喷”高套压溢流事件,因此对钻井方案进行针对性优化,为该井区长兴~栖霞组井段安全钻进创造条件。
In 2020,L203 well block of deep shale gas in South Sichuan Basin has entered into large-scale exploration and development.Due to the same open hole section“lost circulation and overflow coexisting”,High casing pressure overflow event of“lost circulation to overflow”occurred in several wells.Therefore,the drilling scheme is optimized to create conditions for safe drilling in Changxing to Qixia Formation.
