Adsorption characteristics of shale reservoirs in the Jingmen area and application of adsorption potential theory

College of Science, China University of Petroleum, Beijing 102249, China

摘要

摘要: 通过有机碳含量测试、干酪根同位素测定、镜质体反射率测定、X射线衍射和低温CO₂+N₂吸附等手段,对荆门地区页岩样品常规地化性质和孔隙特征进行了考察,结果表明,所取页岩样品有机质含量和成熟度均较高,孔隙结构发育完善。采用重量法对页岩样品进行了等温吸附实验,建立了等温吸附模型并考察了水分和温度对吸附过程的影响,结果表明,页岩样品吸附性能较好,平均吸附量为2.52 mL/g。Langmuir方程可对吸附过程进行较好拟合计算,水分含量越高,温度越高,越不利于吸附行为的发生。采用吸附势理论解释影响页岩吸附性能因子的作用,结果表明吸附势越大越有利于吸附行为的发生。

Abstract: Organic carbon content, carbon isotope analysis of kerogen, X-ray diffraction and low-temperature CO₂+N₂ adsorption tests were usedto investigate the conventional geological properties and pore characteristics of shale samples from the Jingmen area. The results show that the shale samples have high organic carbon content, high maturity, and well developed pore structure. A gravimetric method was used to make isothermal adsorption experiments, and an isothermal adsorption model was established to measure the effect of moisture and temperatureon adsorption. Results show that the shale samples have good adsorption properties with an average adsorption volume of 2.52 mL/g. A Langmuir model fits well with the adsorption curves. The adsorption capacity of shale samples decreases as moisture content and temperature increase. Adsorption potential theory was used to explain the controlling factors, and the results showed that it is more useful when adsorption potential is high.
