对于油藏工程师来说,了解气、水相渗透率和毛管压力曲线是非常重要的。本文提出了具有一相可压缩流体的两相流的新的数学方法。 该方法在于确定计算动态记录的实测压力与模拟压力之间差值目标函数。然后自动拟合使目标函数达到最小值的最佳毛管压力和气、水相渗透率曲线。其难点仍然是定量指标估算和梯度计算。 此方法已在一维情况下实验,并应用实例证明了算法的有效性。同时证明在二维和三维中也是有效的。 For reservoir engineers, understanding gas, water phase permeability and capillary pressure curves is very important. This paper presents a new mathematical method for two-phase flow with one-phase compressible fluid. The method consists in determining the objective function for calculating the difference between the measured pressure and the simulated pressure of the dynamic record. The best capillary pressure and gas-water permeability curves that minimize the objective function are then automatically fitted. The difficulty is still quantitative index estimation and gradient calculation. This method has been tested in one dimension, and an example is given to prove the effectiveness of the algorithm. At the same time, it is also proved effective in 2D and 3D.
