煤层气解吸扩散运移动力学

煤层气运移动力学,是研究煤层气成藏机制的重要基础理论。煤层气解吸扩散运移是复杂的动力学过程,物质在地质场的质量交换和质量传递,须具备一定的动力和经受一定的阻力来实现,这些作用力是诸多综合因素的合力,其变化过程可从物质变化的速度等力学量、温度压力等热力学量、组分浓度等化学量来描述。

DYNAMICS OF DE-ABSORPTION,DIFFUSION AND MIGRATION OF SEAM GAS

The dynamics of migration of seam gas is a problem of important basic theory in the study of formation mechanism of seam gas. The de-absorption, diffusion and migration of seam gas are a complicated dynamic process. The mass interchange and transmission of material in the geological field must be fufilled with a certain dynamic and by experience of a certain resistance. These efforts are the resultant of forces of many comprehensive factors. And their change processes can be described with the mechanics amount of the velocity of material change ,the thermodynamics amounts of temperature and pressure and the chemical amount of constituent thickness.
