通过资料收集、野外地质调查、页岩气调查井勘探、样品分析测试，对黔西南区上古生界四套含页岩系有机质页岩发育特征、地球化学及储层特征进行了综合研究。认为黔西南区有机质页岩具有厚度较大、埋深适中、有机碳含量和热演化程度较高、孔隙度和含气量较大等特点。根据页岩气有利区优选参考标准，优选出三套目的层系7个页岩气有利区，通过对页岩气有利区资源量计算参数赋值，获得P50概率下的页岩气地质资源量2.22万亿m3，可采资源量0.40万亿m3，页岩气资源潜力较大，具有较好的勘探开发前景。%Through data acquisition, field geological surveying, shale gas investment well exploration, and sample analysis and test, car-ried out comprehensive studies on development, geochemical and reservoir characteristics of 4 sets of organic shale contained rock se-ries in Upper Paleozoic Group, southwestern Guizhou. Considered that the organic shale in the area has features of rather large thick-ness, moderate buried depth, higher organic carbon content and thermal evolution degree, larger porosity and gas content. Based on shale gas favorable area preferential reference standard, has selected 3 sets of target series of strata and 7 shale gas favorable areas. Af-ter favorable area shale gas resource estimation parameter assignment, obtained P50 shale gas geological resources 2 200 billion m3, in which, exploitable 400 billion m3. Thus, the shale gas resource has larger potential in the area with better exploration and exploitation prospect.
