本文介绍了华北盆地西部四种隐蔽油藏的圈闭条件及其成因,指出隐蔽圈闭主要沿不整合面和岩相变化带发育。文章侧重介绍了近年来本区勘探剥蚀不整合圈闭,超覆圈闭、岩性圈闭和古潜山圈闭的初步实践和方法。
Abstract
This paper presents the trap requirements and origin of four types of subtle oil pools and points out that subtle traps arc mainly distributed along unconformities and litho-facies change zones. The methods recently used for searching truncated unconformity traps, overlap traps, lithologic traps and hurried hill traps in the region are particularly described in the paper, as well as the preliminary exploration practice,
