针对高含束缚水气藏的特性,研究了束缚水存在对变形介质气藏渗流的影响,建立了考虑束缚水存在下的变形介质气藏流固耦合渗流数学模型,详细描述了变形介质气藏流固耦合渗流数学模型的建立过程和建立方法,并对渗流新模型的求解方法进行了探索。该渗流模型的建立对正确认识和高效开发变形介质气藏具有重要意义。

In consideration of high irreducible water containing gas reservoirs,the effect of irreducible water on the percolation of formational media gas reservoirs is studied.A mathematic model of liquid-solid coupling and percolation for deformational media gas reservoirs is established,under the condition of irreducible water existence,and the process and method for establishing the model are described.The method for solving the new model is studied.The percolation model is of great significance for correct recognition and high efficient development of gas reservoirs with deformational media.
