摘　　要：针对孤岛油田西南缘地质结构及沉积特征,利用石油地质学理论和有机地化分析测试技术对其成藏条件、油源对比、输导体系及成藏模式进行了系统研究。结果表明,受油源平面分带性和输导体系差异性的控制,孤岛油田西南缘发育渤南型断阶输导—网毯汇聚和孤南型砂体输导—网毯汇聚2种油气成藏模式,前者控制了该区西南部的油气成藏,后者控制了东北部的油气成藏,而中部地区的油气成藏受2种模式的共同控制。Reservoir-forming conditions, oil-source correlation, transmission system and reservoir-forming patterns of the southwest of Gudao oilfield are researched systematically using petroleum geology theory and organic geochemical analysis technology according to its geologic structure and sedimentary characteristics. The results show that the southwest of Gudao Oilfield developed in two hydrocarbon reservoir-forming patterns, i. e. Bonan-source, fault-steps transmission, meshwork-carpet type and Gunan-source, sand transmission, meshwork-carpet type,which are controlled by plane zonality of oil -source and difference of transmission system. The former pattern controls hydrocarbon reservoir-forming in the southwest of the area, and the latter controls the hydrocarbon reservoir-forming in the northeast of the area. The middle area is controlled by both the two patterns.
