摘要
对煤层进行注水是目前比较常见的增加瓦斯抽采效率的方式,研究注水煤层瓦斯运移规律有助于丰富瓦斯渗流理论,而且还是合理部署水力化措施进行瓦斯抽采的理论依据。对注水煤层瓦斯运移规律的研究成果进行了系统的梳理,就相关理论陈列的观点进行了详细的分析。指出了注水煤层瓦斯运移规律研究的发展方向:考虑水的各项性质对煤体吸附解吸规律的研究;基于外部环境的变化对注水煤层瓦斯运移规律的研究;注水条件下基于瓦斯非线性渗流规律条件下建立更为精细的多物理场耦合理论的研究。
Water injection of coal seam is a common way to increase gas extraction efficiency, research on the migration of gas of coal seam by injecting water can not only enrich gas seepage theory, but also can provide scientific basis for reasonably arranging water-flooding technology. In the paper, the research results on the gas migration in water injection coal seam were systematically sorted out and the applicability of the relevant theory was described in detail. The development direction of gas migration of water injection coal seam was pointed out： consider the nature of the water to study the adsorption and desorption law of coal; focus on the gas migration in the water-intrusion coal seam and environmental consequences; a more detailed study on the theory of multi-physical field coupling under the condition of water injection and gas nonlinear seepage is proposed.
