摘　　要：根据辽河盆地东部凹陷南段荣兴屯，大平房及桃园3个地区获得工业性油流的77口井不同层段的原油常规物理性质分析资料和随机选择的不同层段16个油样多项地球化学测试结果，综合分析确定上述地区内煤型油占有一定的优势，其次为湖相原油，部分为这两类原油轻－中度降解后形成的中－重质原油，该区发现具有工业规模的煤型油，为我国东部深埋的新生代沉积盆地的油气勘探增加了新领域。Physical analysis of crude oil from different horizons of 77 commercial oil wells and many geochemical tests on 16 crude oil samples which were chosen at random indicate that oil from coal is superior in the south of east sag of Liaohe Basin. A part of crude oil comes from source rocks of lacustine facies, the rest is middle and heavy density crude oil which is low or middle-grade degraded oil from above crude oil. Discovery of commercial oil from coal will add the new content and direction to petroleum exploration in Ceno-zoic deeply buried sedimentary basin in the east of China.
