摘　　要：储层中固体沥青准确定量还没有一个有效的方法。通过对四川普光气田长兴组-飞仙关组碳酸盐岩储层有机碳的测试分析,定量评价固体沥青,并采用物质平衡法(C元素和H元素),计算古油藏原油量及其裂解生气量,得出长兴组储层沥青质量分数平均为0.17%,飞仙关组储层沥青质量分数平均为0.29%。储层性质越好,有机碳(沥青)含量越高;Ⅰ,Ⅱ,Ⅲ类储层的平均有机碳质量分数分别为0.42%,0.35%和0.21%。普光圈闭长兴组-飞仙关组古油藏原油总量约为0.501×109t,古油藏裂解生成的天然气总量约为0.361×1012m3。There has not been a useful way in accurate quantification of the solid bitumen in reservoirs.The solid bitumen was quantitatively evaluated by analysing the TOC in the carbonate rock reservoirs of Upper Permian Changxing Formation and Triassic Feixianguan Formation,and the ancient oil reservoir crude oil content and its oil-cracking gas content were calculated by the material balance method （C and H）.The result shows that the average bitumen content of Changxing Formation and Feixianguan Formation is 0.17% and 0.29%.The better of the reservoir quality,the higher content of the TOC （bitumen）.The average TOC value of Type Ⅰ,Ⅱ and Ⅲ reservoirs is 0.42%,0.35% and 0.21%.The total ancient oil reservoir crude oil content of Changxing-Feixianguan Formations in Puguang is about 0.501×109 t and its total oil-cracking natural gas content is about 0.361×1012 m3.
