对于我国煤层而言,其主要呈现出渗透率低、吸附强、解吸速度慢等特点,使得煤层试验井的产量较低,进而发生快速的衰减;且低渗透煤储层中的甲烷在运移的过程中还会发生相互制约的问题,对于低渗透煤储层煤层气的开采带来了较大的困难,如何采取有效的技术途径来提高低渗透煤储层煤层气的开采率已经成为相关行业发展中亟待解决的实际问题。为此,本文围绕低渗透煤储层煤层气的开采有效技术途径进行了深入的研究。 For China’s coal seams, its main features are low permeability, strong adsorption, slow desorption and other characteristics, making the production of coal seam test wells lower, and then rapid decay; and low-permeability coal methane migration The mutual restraint problems will occur in the process, which brings great difficulties for the exploitation of low permeability coalbed methane and how to take effective technical measures to improve the recovery rate of low permeability coalbed methane has become a relevant The practical problems to be solved in the development of the industry. Therefore, this paper focuses on the effective technical ways of mining CBM in low permeability coal reservoirs.
