摘要： 马朗凹陷二叠系以下的火成岩以玄武岩为主,地层耐研磨性强、可钻性差,钻井过程中钻速低。对取自现场的岩心进行可钻性试验,建立了岩石可钻性模型,计算了牙轮钻头与PDC 钻头可钻性级值,并结合钻头的结构特点进行了钻头优选。结果表明,对于该地区二叠系以下低钻速的玄武岩地层,选用推荐的钻头与其他钻头相比,机械钻速提高了50%以上,缩短了钻井周期,达到了优质快速钻井的目的,对玄武岩地层钻头选型具有重要的指导意义。

Abstract: The main lithology of the igneous rocks under the Permian in Malang sag is basalt with the characteristics of strong abrasion resistance, low drillability and low drilling rate. This paper tests the drillability of the cores from the field, develops rock drillability model, computes the drillability grade of cone bit and PDC bit and optimizes the bit according to the bit structural features. The results indicate that in light of the basalt strata under Permian, using recommended bit has increased the mechanical drilling rate by 50% compared with other bits, shortened the drilling cycle, and attained the aim of excellent and fast drilling.

Key words: Santanghu basin, Malang sag, basalt, drillability, bit optimization
