摘　　要：页岩不仅能成为生油岩和盖层,还能成为储层,实现自生自储。油页岩孔隙的研究有助于页岩油勘探层位选取,资源潜力评价,原位开采,干馏温度的确定等多方面研究。油页岩的孔隙度主要受干酪根和矿物组分影响,通常其与TOC含量呈正相关。而构造应力、沉积环境、埋深以及含水量等因素也对其有很大影响。因此不同时代以及地域的油页岩孔隙度受控制因素影响会存在一定差异。油页岩热解过程中,半焦孔隙度整体上呈不断增大的趋势,但在达到一定温度后,孔隙度将不在发生明显变化。Shale can not only be considered as oil source rock, but also can be reservoir, as a result of self generation and self storage. Study of oil shale porosity contributes to relative research, such as selection of exploration layer of shale oil, evaluation of resource potential, in situ mining and determination of the temperature of carbonization. The oil shale porosity is mainly determined by kerogen and minerals,and usually seems positively correlated with TOC content. What＇s more, the tectonic stress, sedimentary environment, buried depth and water content also have a great influence on the porosity. Therefore, there will be some differences of factors that control porosity for oil shale in different times and regions. During pyrolysis of oil shale, semi coke porosity is a trend of increasing on the whole before reaching a certain temperature, and then that porosity will not change significantly.
