摘要
已有的诸多研究表明,瓦斯在煤体内的流动属非线性流动。依靠自行设计的煤岩渗透特性测试装置,采用实验研究的方法,建立了考虑吸附作用影响的煤岩非线性渗流方程,并通过对煤岩非线性渗流的力学特征分析,阐述了吸附作用对煤岩非线性渗流特性的影响机制。考虑吸附作用影响的煤岩非线性渗流方程,可应用于煤层瓦斯流动理论及开发计算研究。
Previous many studies showed that gas flowing in coal body was a nonlinear flow. In this PaPer,a nonlinear equation of gas seePage in coal and rock with considering the adsorPtion effect was established by using the self-designed coal and rock seePage ProPerty test device and the exPerimental methods. Based on the analysis of the mechanical characteristics of the nonlinear gas seePage in coal and rock,the influence of the adsorPtion effect on the nonlinear gas seePage ProPerties in coal and rock was exPounded. This nonlinear equation of gas seePage in coal and rock with considering the adsorPtion effect can be used for the study of the coal-seam gas flow theory and the develoPment of coal-bed methane.
