【摘要】：本文主要目的层为松辽盆地北部白垩系地层姚家组葡萄花油层,由于油气的分布与断裂的发育和活动有着密切关系,不同期次断裂发育和封闭演化对凹陷内油气的聚集、运移和保存有着不同的影响,同时前人对该研究区研究的深度不够,对进一步油气勘探造成了很大的困难。本文开展对升平-卫星地区成藏条件的再认识,就是要在目前研究的基础之上,结合三维地震资料、测井资料和分析测试资料,进一步对升平-卫星地区葡萄花油层中断裂活动时期、断裂形成演化历史、断裂系统划分、断裂侧向封闭性、断裂输导以及与断裂相关圈闭的有效性评价进行细致研究,同时结合油水分布规律研究、油藏解剖分析等手段,综合其他成藏因素,对升平-卫星地区断裂控藏作用进一步认识,优选出有利评价区块,为升平-卫星地区进一步勘探及开发提供理论依据,最终达到油田扩边,增产上储的目的。通过以上的研究,总结研究区断层对油气成藏的控制作用主要体现在以下几个方面:(1)油源断裂控制着油气藏的分布,离油源断裂越近的圈闭更易形成油藏;(2)断裂侧向封闭性对油气有这很强的控制作用,研究区28个断圈平均充满程度94.7%;(3)断砂匹配类型对油气成藏有很好的控制作用,源内反“屋脊式”正断层最容易进行侧向冲注,从而在两盘的圈闭更易形成油气藏,源外断砂配置类型中f型断砂配置类型对油气成藏最有利;(4)研究区发育大量的断层相关圈闭,主要为断鼻、断块以及断背斜三类,油气主要分布在断背斜和断块圈闭中;
[Abstract]:The main target layer in this paper is the Miaojia formation of the Cretaceous strata in the northern Songliao Basin. Because the distribution of oil and gas is closely related to the development and activity of faults, the accumulation of oil and gas in the sag is influenced by the development of faults at different times and the evolution of sealing. Migration and preservation have different influences, and the previous researches on the study area are not deep enough, which makes it very difficult to further oil and gas exploration. In this paper, the re-understanding of the conditions of reservoir formation in Shengping-satellite area is to combine three-dimensional seismic data, logging data and analysis and test data on the basis of current research. Furthermore, the paper makes a detailed study on the active period of the faults in the Gaohua reservoir, the evolution history of the faults, the division of the fault system, the lateral sealing of the faults, the migration of the faults and the evaluation of the effectiveness of the traps associated with the faults in the Shengping-Satellite area. At the same time, combined with the study of oil-water distribution law, reservoir anatomy analysis and other reservoir forming factors, further understanding of the role of fault and reservoir control in Shengping-satellite area, favorable evaluation blocks are selected. It provides the theoretical basis for further exploration and development in Shengping-satellite area, and finally achieves the purpose of expanding the edge of oil field and increasing production and storage. Through the above research, the controlling effect of faults on oil and gas accumulation in the study area is summarized in the following aspects: (1) the oil source faults control the distribution of oil and gas reservoirs, and the traps closer to the oil source faults are easier to form reservoirs; (2) the lateral sealing of faults has a strong controlling effect on oil and gas, and the average filling degree of 28 fault circles in the study area is 94.7F; (3) the matching type of fault sand has a good control effect on oil and gas accumulation, and it is easier to carry out lateral thrust injection on the normal fault of "roof type" in the source, so that oil and gas reservoirs can be formed more easily in the trap of two plates. In the configuration type of sand fault outside the source, the type of f type sand fault is the most favorable for oil and gas reservoir formation. (4) A large number of fault related traps are developed in the study area, which are mainly fault nose, fault block and fault back oblique, and oil and gas mainly distribute in fault back slope and fault block trap;
