摘要
通过对岩石可钻性、硬度、抗压强度等参数的测量 ,对大庆油田深井不同深度、不同层位、不同岩性的具有广泛代表性的岩心进行试验。并通过线性回归分析 ,建立了适用性较广的钻井岩石力学特性参数预测模型 ,为深井钻头选型提供了依据。
Based on the measurement of rock drillability, hardness and compression strength, and tests of distinct cores from a variety of deep formations, a general applicable model of predicting drilling rock mechanics properties is established in this paper by linear regression, and it is an effective method to optimize bit style in deep wells.
