就地应力条件下岩石静动态力学性质的研究

岩石力学性质参数可以通过模拟地层应力条件下的室内岩石力学实验得到，但它只能代表一些离散点，所以，在实际应用中的大多数情况下，石油工程师采用连续的测井曲线计算岩石力学参数，然而由于加载频率的不同，计算值与室内准静态条件下测得的参数值有一定的差异，只有校核后的测井曲线才能用于工程应用中。为了从室内实验结果中得到校核后的连续的测井曲线，对模拟就地应力条件下静动态岩石力学性质进行了初步的研究。

Study of static and dynamic mechanical properties of formation rock under in-situ stress conditions

Rock mechanical properties are the essential parameters in the application of petroleum engineering and they could be obtained through laboratory experiment under simulated strata conditions. These measured properties are only for certain formations, so continuous formation properties used in strata engineering are usually from logging data. Nevertheless, result discrepancy exists between these two different methods due to the difference of loading frequency and only could those obtained from logging be applied in petroleum engineering after certain calibration. To obtain calibrated continuous logging data from laboratory tests, static and dynamic properties of formation rock under simulated strata condition were primarily studied.
