中文摘要：

查明页岩气与煤层气的吸附差异对指导其勘探开发具有重要意义.通过测试不同成熟度和有机质（TOC）的煤与页岩的等温吸附曲线,结果表明：TOC 含量是影响页岩吸附的主要因素,成熟度相当的煤与页岩相比,煤的吸附量远远大于页岩,主要是由于成藏特征、物质组成和孔隙结构不同造成的;页岩吸附过程中出现的异常吸附可能有其他的吸附理论支撑.

英文摘要：

Investigating the difference in adsorption properties of shale gas and coalbed methane plays a guiding role in exploration and development. In this paper, isothermal adsorption experiments respectively for coal and shale rock samples with various grades of maturity and contents of TOC were conducted, and the results show that total organic carbon (TOC) is the major factor influencing the gas adsorption capacity of shale, compared to shale with equivalent maturity, coal has much higher adsorption capacity, largely due to the differences in reser-voir-forming characteristics, substance composition and pore structures. The abnormal adsorption of shale may be supported by other adsorption theories.
