ANALYSIS OF STRESS SENSITIVITY FOR IRREDUCIBLE WATER OF GAS RESERVOIR
气藏储层含束缚水的应力敏感性分析

In the exploitation of gas reservoir, the pore pressure decreased with fluid issuing, and pressure between inside and outside of reservoir increased. The pressure has produced deformation of the reservoir rock. So pore volume and porosity of reservoir are reduced. And some free water is released from irreducible water going with fluid issuing. It shows that the irreducible water of pore reduced by the rock deformation, and phenomena of water produced in some gas wells by productivity increased are reasonabl...
