摘要: 长岭断陷泉头组以下深层地层岩石可钻性级值不断增高,机械钻速低,钻井周期长,提高深层钻井速度成为该地区钻井关键的问题。涡轮钻井由于具有高转速、高扭矩特点,能够提高破岩效率,但其特点又决定了其应用具有一定局限性,通过对图深1井涡轮钻井提速分析表明,涡轮钻井在长岭断陷登娄库组地层具有良好的提速效果,在营城组凝灰岩地层达不到提速的目的。

Abstract: In the deep formation below Changling fault Quantou group, because of the increasingly higher rock drillability grade, low ROP and long drilling period, drilling speed improvement becomes the key problem in this area.The high rota-ting speed and high torque of turbo drilling can improve the rock breaking efficiency by high rotating speed and high torque, but it has a certain limitation.By the analysis on the speed-up of turbo drilling in the well Tushen 1, turbo drilling has good speed-up effect in fault Denglouku formation, but it isn’t fit to the Yingcheng group tuff formation.
