薄荷台—大榆树地区扶余油层成藏因素与有利油气富集区研究

Favorable Factors for the Formation and Reservoir of Oil in Fuyu,Bohetai-Dayushu

研究区油气分布受构造、断层、沉积和油源等因素影响,造成油水关系复杂,油藏类型多样,给油藏评价和开发带来困难.薄荷台—大榆树地区扶余油层油气成藏受多种因素制约,对其成藏主控因素的分析是下步油藏评价、油气开发突破的关键.着重分析油气成藏控制因素,建立油气成藏模式,总结油气富集规律,寻找有潜力的油气富集区块,为开发优选有利目标区打基础.研究结果表明,预测研究区存在2个构造和4个岩性有利油气聚集带.

The distribution of oil in the study area is decided by such various factors as structure, fault, sedimentary, oilsource, which makes a variety of reservoir types and complex relationship between oil and water as well as a more difficult reservoir evaluation and development. The reservoir formation in Fuyu, Bohetal - Dayushu is controlled by many factors and the analysis on its major control factors is the key to the breakthrough of reservoir evaluation and development. The basis of development of a favorable target area selection is to focus on controlling factors of oil and gas accumulation, to establishment of oil and gas accumulation model, to sum up oil and gas accumulation and to look for potential oil and gas rich blocks. The results show that the predicted study area has tow two structures and four lithologic conducive to oil and gas accumulation.
