摘要
将渗流力学与弹塑性力学相结合,考虑天然气和岩土骨架之间的相互作用,建立天然气流固耦合渗流数学模型,并给出其数值解。对天然气渗流方程和岩土体变形场方程分别进行离散,得到其相应的泛函方程。根据有限元法原理推出其计算方法,并给出耦合求解方法,这对于真实模拟气藏的开发,指导气田生产具有重要的意义。
By combining percolation mechanics and with the elastoplasticity mechanics and considering the interactions of natural gas and rock body framework the authors established the fluid solid coupled mathematical model and provided the numerical solution. The percolation equation of the natural gas and the rock body deformation equation have been discreted respectively to obtain their corresponding functional equation while the calculation method was derived and the coupled solution method was presented based on the FEM principle. This has great significance to actual simulation of the gas reservoir development and guidance of the gas field production.
