【摘要】 根据国内外研究现状和实际工作总结,提出陆相盆地隐蔽油气藏勘探必须在层序地层学综合研究的框架下统一运用各种相关的地质与地震技术,认为隐蔽油气藏的目标预测和评价可分为工区选择、目标层段确定、圈闭预测及含油气性评价等步骤,并讨论了各阶段的地质-地震综合研究方法,分析了该方法在金湖凹陷戴南组隐蔽油气藏勘探中的应用。更多还原

【Abstract】 According to current situation and actual working summarization both at home and abroad, it is proposed that related geological and seismic techniques shall be universally used for subtle hydrocarbon reservoir exploration in continental basins under the framework of synthetical study of sequence stratigraphy, it is thought that the target prediction and evaluation of the subtle reservoirs are divided into the procedures of selecting work area, determining target zones, predicting traps and evaluating oil and gas bearing properties, and comprehensive geologic and seismic methods used for each stage are discussed, application of the methods in the exploration of subtle reservoir in Dainan Formation of Jinhu Depression are analyzed.更多还原
