中文摘要: 以低渗透多孔介质为研究对象,通过实验得出孔隙度、渗透率随有效压力变化曲线。研究表明,流体在低渗透多孔介质中渗流时,流固耦合效应十分显著。这是因为低渗透多孔介质的孔隙很小,而孔隙度的微小变化,都会对渗透率产生大的影响,因此低渗透介质随有效应力的变化十分明显。由于流固耦合效应的存在,在低渗透油气藏的开发中,不宜采用降压开采,进行油藏数值模拟时,也应进行油藏流固耦合数值模拟。
Abstract:On the basis of experimental study,the law of porosity and permeability versus effective pressure are developed, Because porosity of low permeability media is very small, a little change of its porosity can make its permeability decline rapidly. The paper is useful in solid-fluid coupled simulation of oil reservoir. The paper gives coupled relations in solid-fluid coupled simulation. During the oil and gas field developing,the coupled effect should be considered.
