摘要
富源204井是台盆区富源区块上的一口评价井,二叠系火成岩地层裂缝发育,玄武岩硬脆性强,可钻性差,为提高机械钻速,使用阿特拉扭力冲击器钻穿二叠系地层,该工具与配套的PDC钻头一起使用,消除卡-滑现象,冲击破碎地层,加以旋转,在保证井身质量的同时提高机械钻速[1]。该技术在塔里木探区普遍应用,但在应用过程中遇到一些实际问题,为该工具配套钻头改进提供了参考。
FY 204 Wells is basin zone fuyuan blocks on a appraisal well,Permian igneous rock formation fracture development,basalt hard brittle,poor drillability,to improve the rate of penetration,using atlas torkbuster percussive drill wear Permian strata,which form a complete set of tools and PDC bit are used together,eliminate the phenomenon of card-slide,impact crushing stratum,rotation,to guarantee the quality of the hole at the same time improve the speed[1].This technique is widely used in Tarim exploration area.However,some practical problems are encountered in the application process,which provide a reference for the improvement of the tool.
