摘　　要：渤中凹陷是渤海海域最大的富生烃凹陷,但对其油气资源潜力和分布规律认识不清,制约着油气的勘探进展。以油气成藏体系为评价单元,应用油气成藏门限理论,基于物质平衡原理对环渤中凹陷油气资源潜力和分布特征进行了定量评价。研究结果表明,环渤中凹陷上、下油气成藏组合各划分为6个成藏体系,环凹陷总可供聚集油量为60.265×108t,上、下成藏组合分别为43.185×108t和17.080×108t,总可供聚集气量为27.03×1011m3,上、下成藏组合分别为17.76×1011m3和9.27×1011m3。其中,石臼坨油气成藏体系(Ⅰ)和渤东油气成藏体系(Ⅱ)可供聚集烃量最大,是进一步勘探的有利方向。The Bozhong Sag is the biggest hydrocarbon rich sag in the Bohai Sea area.However,hydrocarbon resource potential and its distribution are not clear,which restricts petroleum exploration.According to the material balance principle and the hydrocarbon accumulation threshold theory,the resource potential and distribution characteristics of hydrocarbons were evaluated quantitatively with hydrocarbon accumulation systems as evaluation units.The upper and lower plays in the Bozhong Sag and surrounding areas each can be divided into six hydrocarbon accumulation systems.The total afforded accumulation hydrocarbon quantity in the Bozhong Sag and surrounding areas is 60.265×108 t of oil（43.185×108 t in the upper play,17.080×108 t in the lower play） and 27.03×1011 m3 of gas（17.76×1011 m3 in the upper play and 9.27×1011 m3 in the lower play）.The Shijiutuo（Ⅰ） and Bodong（Ⅱ） accumulation systems are the further exploration areas with the greatest afforded accumulation hydrocarbon quantity.
