对荣兴屯地区古近系油气藏主要类型及其分布特征进行总结以揭示其潜在的增储目标。利用地震、钻测井与测试等资料,通过制作已有油气藏分布的平面图、剖面图,明确了油气藏类型多为断层有关的构造型及复合型油气藏,平面上多呈点状与带状主要依附于荣兴屯等主断裂及其伴生构造上,其富集程度表现为南优北差、西富东贫;油气纵向贫富差异大,主要发育层位依次为东三段、沙一段及东二段,其中以东三段最优;复杂断裂体系与不同类型的储盖组合对油气纵向展布产生了重要影响,使之具有“线运点聚”纵向叠置成片的复式聚集成藏特征。研究结果认为荣兴屯斜坡带是有利的潜在增储目标区,目标类型是与断裂相关的构造型及复合型圈闭油气藏。
The main types and distribution characteristics of Paleogene reservoirs in Rongxingtun area are summarized to reveal their potential target of increasing reserves. By using the data of seismic, drilling, logging and testing, the author made the plan and profile of the existing oil and gas reservoirs and made it clear that the reservoirs are mostly fault-related tectonic and complex reservoirs with many points and belts The shape mainly depends on the main faults such as Rongxingtun and its associated structures. The enrichment degree is mainly Nan Youbei and West Weifudong; the longitudinal difference between rich and poor is large, and the main developmental layers are Dongsan and Shashi And East Section 2, of which the eastern section is the best. Complicated fault systems and different types of reservoir-cap assemblages have an important influence on the vertical distribution of oil and gas, making them " Complex accumulation accumulation characteristics. The results show that the Rongxingntun slope zone is a potential target area for potential enrichment. The target types are tectonic fractures and composite trap reservoirs.
