吸附储层中CO2封存与强化采气研究展望

摘要

介绍了吸附储层中CO2封存与强化采气的研究进展.分析了煤层气/页岩气等吸附储层的典型特点,论述了CO2、CH4及其与煤岩/页岩体间的相互作用特征,探讨了吸附储层中封存CO2的前景与优势、CO2封存与强化CH4解吸动力学过程的模拟思路、CO2地下封存的评价方法,展望了未来的研究发展方向.%The development of CO2 sealing up for safekeeping and CO2 enhanced CH4 recovery in adsorption reservoir bed is reviewed. The typical characteristics of adsorption reservoir bed, including coal bed and shale bed are analyzed. The competitive adsorption capabilities of coal/shale rock between CO2 and CH4 are compared. The advantages, simulation method, and evaluation method of this technology are discussed, and its prospect is presented.
