Data for: Numerical Simulation of Multi-seam Coalbed Methane Production Using a Gray Lattice Boltzmann Method

The data shows the contribution rate of gas production under different permeability contrast. Note that the contribution rate of high permeability seam is always higher than that of low permeability seam. When permeability contrast K1/K2 < 10, the contribution rate varies greatly with the variety of permeability contrast. When permeability contrast K1/K2 > 50, with the increasing permeability contrast, the contribution rate of low permeability seam tends to be 0 and the commingled production is mainly contributed by the high permeability seam.

本数据集展示了不同渗透率对比度（permeability contrast）条件下气产贡献率的变化规律。需注意，高渗透率煤层的气产贡献率始终高于低渗透率煤层。当渗透率对比度K1/K2＜10时，气产贡献率随渗透率对比度的变化幅度显著；当渗透率对比度K1/K2＞50时，随着渗透率对比度持续升高，低渗透率煤层的气产贡献率趋近于0，合层开采的气产主要由高渗透率煤层贡献。
