用测井资料估算岩石力学性质参数的方法介绍

SEVERAL METHODS EVALUATING THE MECHANICAL PARAMETERS OF ROCK THROUGH THE AGENCY OF LOGGING DATA

本文简要介绍了动态弹性参数和岩石内在强度(初始切变强度、单轴压缩强度和抗拉强度)。储集层的应力及断裂压力(初始断裂压力和断裂再开口压力)等参数的计算,展示了用MECHPRO程序计算的实例,讨论了这些参数的应用。

At present, geologists are using the logging data in evaluating the mechanical properties of rocks. This paper reviews the computation of dynamic elastic parameter aad briefly introduces the parametric computation of the inner rock strengths (initial shear strength, uniaxial compressive strength and tensile strength), the stress of the reservoirs, fracture-pressure (the pressure of initial fracture and the pressure of re-opening fracture). Examples of computation are shown by MECHPRO program, and applications of these parameters discussed.
