裂缝性页岩储层的应力敏感实验研究

Experimental study on stress sensitivity of fractured shale reservoir

本文选取涪陵龙马溪组页岩岩样,开展了不同净围压下的应力敏感性测试,得到了无因次渗透率随有效应力的变化规律。

In this paper,the shale samples of Fuling Long Ma Creek formation have been selected and the stress sensitivity tests under different net confining pressure have been carried out,and the variation of permeability with effective stress is obtained.
