沧东-南皮凹陷是大港油田黄骅坳陷主要油气聚集区,已发现7个油田.本次应用层序地层学、储层沉积学对该区进行系统研究,在地层、沉积、湖盆结构等方面取得了新认识.统一了中央隆起带和外围地质分层界限;在孔店组内部存在两个不整合面;进一步认识到孔二段属坳陷型残留盆地,首次提出沧东-南皮凹陷为孔二段、沙河街组两期迭合盆地.沉积体系研究认为孔二段以短轴多物源辫状三角洲沉积为主.

Cang Dong-NaiPi Sag is the main oil & gas Accumulation area in HuangHua Depression of DaGang Oil Feld,where had discovered 7oil fields,and this time using sequence stratigraphy,reservoir sedimentlogy and so on to system research the sag,and get new knows in stratum,deposition,lake basin structure and so on.Define the geological lamination boundary between central uplift zone and the outlying zone;has two planes of unconformity in the Kongdian group:Further know that konger section belongs to the residual depression basin.And for the first time to proposes CangDong-Nanpi sag is an superposition basins by konger section and shahejie group.The deposition system research thought that the konger section is mainly minor axis,multi-source,braided delta deposit.This research results have effectively instructed the exploration of lithologic oil pool.
