| 中文摘要:高升北部地区是渤海湾盆地辽河坳陷重要的油气富集区,正确认识高升北部地区油气成藏条件对于弄清该区的油气分布规律具有重要意义。综合利用地质、地球物理、地球化学和计算机技术对高升北部地区油气成藏的研究表明,高升北部地区具备油气成藏的有利条件,较好的烃源岩经历了有机质的低成熟—成熟演化阶段,扇三角洲前缘砂体是最重要的油气聚集区,储集砂体主要发育在高81井—高70井区带。本区烃源岩有机质的成熟度和储集砂体的发育程度是决定油气藏形成最重要的因素。 |

| Abstract:The northern Gaosheng area is a prolific zone for petroleum accumulation in Bohai Bay Basin. An analysis of the petroleum accumulation in this area is therefore of great significance in the correct understanding of the conditions and the model for petroleum accumulation. The formation, migration and accumulation regularities of petroleum in northern Gaosheng area were studied by using integrated geological, geophysical and geochemical methods and computer techniques. It is shown that there exist favorable conditions for the formation of the hydrocarbon reservoir, and that the hydrocarbon source rock has passed through the evolution of the organic matter from low maturity to maturity. Sand bodies in the delta front are the most important oil and gas reservoir. The favorable developing area of the reservoir is located at Gao 88-Gao 70 wells belt in the southern part. The maturity of the organic matter and the developing area of the reservoir in northern Gaosheng constitute the most important factors for the formation of the oil and gas accumulation. |
