页岩气吸附作用研究进展

Research of Shale Gas′Absorption

综述了美国页岩气产量、丰度和储层孔径范围以及我国南方部分地区页岩气丰度和储层孔径范围,两者大体相当.我国待开发页岩气主要以游离态及吸附态存在,吸附态主要吸附在有机质和无机粘土矿物固体表面,分析了微观物理吸附的实质为分子间吸附力和吸附势的作用,这可以解释不同固体对各种吸附分子吸附的差异.论述了温度和压力、粘土矿物和TOC%、Ro、水介质对页岩气吸附的微尺度影响研究进展,最后指出加强页岩气微观研究的不足及具有的深远意义.

Compared with the shale gas production, abundance, and reservoir pore size range in America. it is nearly equal in China South. Shale gas to develop in China mainly exists in supercritical physical absorption pattern and is absorbed mainly in organic matter and inorganic clay mineral solid surface. The essence of microcosmic physical absorption is ab- sorption force between the molecules and adsorption potential, which can explain the solid adsorption of molecules ad- sorbed on differences. Discuss the temperature anti pressure, RO and ＂FOC%＂, water medium, the influence of electro magnetic field in shale gas adsorption and at last point out the study＂ significance.
