Progress of Seepage-Rock Mass Coupling Theory and Its Application

This paper presents a simple review about fluid solid coupling theory and mainly refers to the interaction between rock mass and fluid. Several important questions existing in the theoretical study, including effect stress laws,the systematical coupling models, the degree of coupling and the numerical analysis methods, are discussed.Two practical problems in the petroleum exploitation about casing collapse and sand production are taken as examples to make some explication. Therefore, a further development in coupling theory of seepage rock mass will promote the advance of the geomechanics in petroleum industry.
