摘要
收集了大量钻井岩石力学性能指标,包括岩石可钻性、压入硬度、研磨性、抗压强度、泊松比、渗透率等10余种。应用聚类分析、主成分分析、回归分析、关联度分析等多元统计方法及灰色系统理论方法对这些数据进行了处理。结果表明:岩石各性能指标间存在着不同程度的相关关系,其中岩石可钻性和压力硬度的关系最为密切,存在着近似的幂函数关系。
Rock mechanical properties include many indicators, such as, drillability, hardness, plastic coefficient, compressive strength, modulus of elasticity, permeability, etc. To reveal the correlation among them, three statistical samples are collected. Based on the multivariate analysis of the samples, it is concluded that the different indicators are correlative. The correlation between drillability and hardness can be described by power function.
