| 摘 要： | 在前人有关沙四段油源、油气充注期次等研究成果的基础上,通过盆地模拟技术,分析了渤南洼陷的沉降特征、古温压场的形成与演化.在油气两次充注的背景下,渤南洼陷的沙四段油气成藏经历了三次重要的成藏时期,即东营期第一次充注期、馆陶期第二次充注早期、明化镇期第二次充注晚期.其成藏过程严格受古能量场的控制,特别是明化镇期的快速增压对沙四段晚期成藏具重要影响.渤南洼陷沙四段油气遵循"压浮双力驱动、断砂网状输导、短距就近捕集、晚期复合成藏"的规律.

| Abstract: | Bonan sag is an oil-enriched subsag in Zhanhua depression,Jiyang depression.Member 4 of Shahejie Formation(Es4) has great potential for oil and gas exploration.Based on the known research on the oil-source rock in Es4 and phrases of hydrocarbon infilling,the paper analyzes the characteristics of subsidence,formation and evolution of the temperature-pressure system.On the background of the two phrases of hydrocarbon infilling,the oil and gas in Es4 experienced three important periods to accumulate: Dongying ... |
