Abstract
Because of the poor drillability, dense lithology and local high gravel content in Denglouku formation, Yingcheng formation, Shahezi formation and Huoshiling formation in Lishu fault block;and rock hardness is up to Grade 7.Low drill-ing efficiency and short service life of cone bit were the difficulties for traditional drilling technology, and the drilling effect was not ideal for PDC bit trial.But with turbodrilling technology, the average ROP increases 4 times, the drilling cycle is shortened and the comprehensive drilling cost is greatly reduced.The practice shows that turbodrill+impregnated diamond drilling technology is effective with high abrasive, high compressive strength and speeding up for drilling in high tempera-ture deep well.关键词
