摘要: 从煤储层在构造抬升过程中异常压力的成因机理入手,通过沁水、塔巴庙地区抬升过程的定量模拟研究,分析在整个抬升过程中煤储层流体体积的变化所引起的流体压力的变化情况,从而反映储层压力在整个构造抬升过程中的动态演化过程,得出“抬升过程是异常低压形成的重要机制”的结论。

Abstract: Considering the genetic mechanisms of abnormal pressure of coal reservoir in process of geologic uplifting,through quantitative simulation analysis on geologic uplifting process in Qinshui basin and Tabamiao district,the variety of fluid physical volume of coal reservoir causing pressure variety of coalbed gas is analyzed,which reflects the dynamic evolvement process of whole reservoir pressure in the process of geologic uplifting,resulting in conclusion that means the geologic uplifting process is an important mechanism of abnormal low pressure.
