特低渗透油藏变渗透率场油藏数值模拟研究
摘要
Abstract
According to the percolation characteristics of fluid in ultra-low permeability porous media, and con-sidering the reservoir permeability varying with the pressure gradient, the mathematical model of the variable permeability reservoir is established. Based on the black oil model, the method of the variable permeability numerical simulation for the ultra-low permeability reservoir is presented, the variable permeability numerical simulation is applied for the Hong 75 block of ultra-low permeability reservoir in Jilin Oilfield. The simulation results show that the reservoir permeability reaches constant in a small range near the wellbore while the variable permeability percolation plays a dominant role in the fluid percolation of formation. The variable permeability percolation numerical simulation can predict the percolating process of the fluid in the low permeability porous media more exactly.关键词
