摘要
运用高精度层序地层学的理论,系统地划分和对比泌阳凹陷上白垩统至古近系不同级别的层序地层单元,建立了凹陷内各级层序地层单元的对比框架,并指出了凹陷北部斜坡带高位进积三角洲复杂断块群油气藏发育区、北部斜坡枢纽带内低位扇断层-岩性油气藏、深凹区湖扩展期和高位期滑塌浊积体及湖底扇透镜体圈闭发育区及南部陡坡带岩性油气藏发育区。以此为指导,对凹陷北部斜坡、深凹区和南部陡坡3个构造带发育不同类型圈闭的特点,开展了复杂圈闭的地震识别和预测技术研究,发现了一批隐蔽目标,钻探后取得了明显的地质效果。
The theories on high-resolution sequence stratigraphy were applied to the systematical recognization and correlation of the sequence stratigraphic units of different orders for the Upper Cretaceous to Paleogene in the Biyang Depression and to the establishment of correlation frameworks for sequence stratigraphic units of each order.We identified several favorable hydrocarbon reservoir types,including the complex fault block reservoirs of the high-stand prograde delta in the northern slope zone,the fault-lithologic reservoirs in the low-stand fan of the hinge zone in the northern slope,the lenticular reservoirs in the slump turbidite and sublacustrine fan in the deeply-sagged area,and the lithologic reservoirs in the southern steep slope zone.Based on these discoveries,we studied the various trap types developed in the northern slope zone,deeply-sagged area and the southern steep slope zone and carried out research on their seismic recognition and prediction.Many subtle reservoirs were identified through seismic prediction and proved through drilling.
