摘    要:米仓山-大巴山前缘页岩气基础地质调查万地1井钻遇二叠系吴家坪组巨厚层硅灰岩、燧石灰岩,坚硬致密,裂隙、溶隙、溶洞极发育,钻进过程中钻井液漏失严重甚至失返,造成钻进困难。先后采用了随钻堵漏、桥接材料堵漏、水泥砂浆堵漏、胶质泥浆-水泥浆堵漏、拦截式堵漏工艺技术,基本解决了钻进中钻井液失返问题。

关 键 词:钻井液漏失  随钻堵漏  桥接材料堵漏  水泥砂浆堵漏  胶质泥浆-水泥浆  裂缝地下水径流  拦截式堵漏工具  页岩气基础地质调查

Abstract:In the drilling of Wandi 1 well for basic geological survey of shale gas in Micangshan-Dabashan, the Permian Wujiaping formation thick layer of siliceous limestone and flint limestone were encountered, which were hard and compact with the development of fracture, dissolved fissure and karst caves. The serious circulation loss even no-return happened, which resulted in difficult drilling. Plugging while drilling, bridging material plugging, cement mortar plugging, colloid mud-cement slurry plugging and interception plugging technologies were adopted, no return of drilling fluid was solved.
Keywords:circulation loss  plugging while drilling  cement mortar plugging  colloid mud-cement slurry  fissure underground water runoff  plugging by interception tools  basic geological survey of shale gas
