摘要
通过高精度层序地层学和石油地质基本条件的研究,分析金湖凹陷戴南组隐蔽油气藏的主要类型,指出构造形态、盖层发育、圈闭与油气运聚的时空配置是隐蔽油气藏成藏主控因素,总结了隐蔽油气藏成藏模式,并提出三河次凹西斜坡北段和龙岗次凹周缘斜坡带为戴南组最有利的隐蔽油气藏分布区。综合应用地震地质层位标定、精细构造解释、井约束反演和地质综合评价等多项技术,对LZ三维地震区块戴南组隐蔽油气藏进行了预测和评价。
By research of high resolution sequence stratigraphy and basic condition of petroleum geology, the dominant styles of subtle.eservoir of Dainan formation in Jinhu depression has been summarized in this paper. The structure, thickness of coverage layer and cooperation of subtle trap with petroleum migration of reservoir are the dominant controlling factors of subtle reservoir. The mode of subtle reservoir has been synthesized. Based on the mode, the slopes on the west of Sanhe depression and around Longgang depression were best beneficial distribution areas of subtle reservoir have been pointed out. By using multiple technology as comparison of seismic -geology interface, precise interpretation of structure, well -restricted reverse modeling and synthetic evaluation of geology, the subtle reservoir of Dainan formation in LZ area has been predicted and evaluated.
