摘要
Abstract
Chang-2 member of Yanchang Formation in a block of Ordos Basin is taken as the research object, combined with field emission scanning electron microscopy (FESEM) and image processing technology, to observe and process thin section photos and to test rate-controlled mercury injection respectively, by which the pore size distribution and their differential mechanisms is represented via using statistics method. Compared with the pore size distribution obtained by rate-controlled mercury injection and by thin section after the threshold value divided and binaryzation process, the two methods are consistent in reflecting the main pore size, and the pore size distribution obtained by thin section has the advantage of continuity.关键词
