摘　　要：通过高分辨率层序地层划分与对比、全三维地震资料构造解释与微构造分析、测井 地震约束波阻抗反演、地震资料油气预测等配套新技术的综合应用 ,重新建立了东辛油田东南部地区的油藏地质模型。在对成藏规律认识的基础上 ,提出了工区构造油藏和岩性油藏两类共 7个滚动勘探目标。前者主要为沙三中以下目的层 ;后者为微构造或斜坡背景下的岩性尖灭型圈闭 。The technologies of stratum division and correlation using high resolution sequence stratigraphy,the structure interpretation of full three-dimensional seismic data,the acoustic impedance inversion with log and seismic data and prediction of oil and gas with seismic data were comprehensively applied to re-establish the geological model for the east-southern reservoir in Dongxin Oilfield.The laws of reservoir generation were analyzed,and seven roll exploration objects were proposed.These objects can be divided into two types of structural oil pools and lithologic oil reservoirs including seven objects of roll exploration.The first type is the deeper reservoir under the midst of third section in the Shahejie Formation,and the second type is the lithologic pinchout oil reservoir on the background of micro structure and slope.The types of sand body in the studied area include the delta front sheet sand and the deeper water turbidite(haclberry)sand.The former is located between the upper third section in Shahejie Formation and the lower second section in Shahejie Formation.The latter is between the fourth section in Shahejie Formation and the midst of the third section of Shahejie Formation.
