摘要:
针对页岩储层复杂的孔隙结构,运用低温氮气吸附实验,优选非定域密度泛函(NLDFT)计算方法,对吸附数据进行处理,实现对富有机质页岩样品纳米级孔隙微孔和介孔的连续测量。实验结果表明:滇黔北地区龙马溪组下部富有机质页岩既发育微孔,也发育介孔,页岩纳米级孔隙呈狭缝型和墨水瓶状,平均比表面积为14.24 m2/g,平均孔体积为12.99 mm3/g,微孔提供了绝大多数的比表面积; 有机碳含量是影响滇黔北地区龙马溪组富有机质页岩纳米级孔隙发育的主控因素,黏土矿物含量的增大降低了页岩的比表面积。
Abstract:
For complex pore structure of shale reservoir, using nonlocalized density functional theory(NLDFT)method, the low temperature nitrogen adsorption experiments were carried out to quantitatively evaluate the distribution of micropores and mesopores of organic-rich shale samples. The experimental results show that micropores and mesopores are both developed in the study area. The nanopore shapes of organic-rich shales are mainly slit-like and inkbottle-like, with an average specific surface area of 14.24 m2/g and an average pore volume of 12.99 mm3/g. The micropores provide most of the specific surface area. Total organic content is the main controlling factor for the development of nanoscale pore structure of organic-rich shale, and the increase of clay content decreases the specific surface area of organic-rich shale.
