摘    要:松辽盆地松南油页岩地层水敏性强,钻探施工过程中极易水化、剥落,甚至垮塌。2018年中国地质调查局在扶余-长春岭矿区布置了8口油页岩地质调查井,岩矿心采取率、终孔直径和岩心直径、孔斜率等的要求均较高。通过采用S95+5绳索取心钻进工艺,对钻孔结构、钻头选型、钻井液、钻进参数进行优化,成功地解决了油页岩地层护壁难问题,并且高质量地达到了工程质量要求。总结了油页岩地层绳索取心钻进关键技术。

关 键 词:松辽盆地  油页岩  地质调查井  绳索取心钻进

Abstract:The Songnan oil shale formation in the Songliao Basin is highly water-sensitive, which is prone to be hydrated, spalled, and even collapsed during drilling. With use of the S95+5 wireline coring process, and optimization of the borehole structure, bit type, drilling fluid and drilling parameters, the difficulty of protection of borehole walls in oil shale formation was successfully solved, achieving engineering quality requirements. This paper summarizes the key technologies in wireline coring in oil shale formation so as to provide technical reference and guidance for the similar drilling works.
Keywords:Songliao Basin  oil shale  geological survey wells  wire-line core drilling
