摘要： 本文首次对我国西昌盆地、鄂尔多斯盆地及江油马角坝地区不同时代破酸盐岩油气源
岩研究衣明，在油气源岩演化的各个阶段均可形成有机包裹体.有机包裹体是油气源岩中烃类物质的原始样品，它记载着油气源岩演化过程中所发生的所有事件及有关信息。在油气源岩评价中，有机包裹休的类型、特征、古温度、含量及组分等参数，结合其它研究结果，可有效地对油气源岩的演化程度、生油热历史、有机质热演化分区、油气资源量以及油气源岩性质和成因等进行综合研究和评价。实践证明该评价方法是可行的。

Abstract: Based of the ersearch of carbonate-type oil/gas source rocks from lower Permain in Xi-chang Basin, lower Ordovician in Ordos Basin，and lower Carboniferous in Majiaoba,Jiangy-ou, the author in this paper finds that organic inclusions could be formed in deck stage of the thermal evolution of oil/gas source rocks. Organic inclusions are the primary samples for hy-
drocarbon matter in oil/gas source rocks，and thus embody all sorts of events and informa-tion associated with hydrocarbon matter occurring in the thermal evolution of carbonate一type oil or gas source rocks. Therefore，in the evolution of oil/gas souce rocks，the inclusion's types，characteristics，paleo一temperature，quantity,composition, and some oth-er parameters will offer an effective approach towards the study of (1) the thermal evolution
degree and matueity stage of oil/gas source rocks;(2) sedimentary basin paleo一tenperature and the thermal evolution history of oil source rocks;(3) the regional distribution and divi-sion of organic matter maturity in oil/gas rocks;(4) assessment.of oil/gas resource abun-dance;and (5) the nature and origination of oil/gas source rocks.
