根据岩屑硬度和塑性系数确定地层岩石的力学性质

Rock Mechanical Properties According to Hardness and Plasticity Coefficient of Rock Cuttings

在石油钻井和开发过程中准确掌握地层岩石的力学性质是非常重要的工作。本文通过对新疆油田部分油气井在钻井过程中获得的岩屑,在实验室测得了岩屑的硬度和塑性系数,在大量试验数据基础上,建立了岩屑硬度和塑性系数与岩石可钻性、抗压强度和研磨性的相关关系,从而获得钻井地层岩石的力学性质。

It is important to know about the formation mechanical properties during the process of oil drilling and exploitation. The relevant relations between hardness and plasticity coefficient of rock cuttings and drilling rock capability, compressive strength and grinding are described based on the data of the experimenta on the rock cuttings from the Xinjiang Oil field. With the relevant relations, the mechanical properties of rock in the drilling formation can be gained.
