| 摘 要： | 准噶尔盆地西北缘乌夏断裂带二叠系地层埋藏深度较大,岩性较复杂,岩石研磨性强、可钻性差。为解决在该地层机械钻速低、进尺短及钻头使用寿命短等诸多问题,根据已完钻井的钻井及测井资料,结合室内微钻头可钻性实验,对二叠系地层岩石力学特性进行了分析评价,确立了将单轴抗压强度、内聚力、内摩擦角和可钻性级值作为牙轮和PDC钻头选型的基础参数和选用标准,形成了适合于乌夏断裂带二叠系地层的钻头优选技术。

| Abstract: | In Wuxia fault zone,northwestern Junggar Basin,the Permian is characterized by deep burial depth,complex lithology,stronger rock abrasiveness and poor drillability,which may bring about such problems as low penetration rate,short footage and service life of drilling bit.In this paper,based on some drilling and well-logging data from drilled wells,the Permian rock mechanics are analyzed at first;and then some basic parameters of cone and some standards to select PDC bit are determined,including uniaxial comp... |
