计算结果还表明，中等硬度的岩石溶洞的压缩系数都很小，油藏工程计算中可将其忽略。
The compressibility of vuggy rocks with medium hardness is usually small and can be neglected in the calculations of reservoir engineering.
并在该模型中用岩石硬度、塑性系数和弹性系数来反映岩石的力学性质，从而使模型具有较宽的应用范围。
Furthermore, hardness, plastic coefficient and elastic coefficient have also been introduced in this model to describe the rock nature in con...
