摘要
在构造背景、层序特征和沉积体系综合分析的基础上,总结了阜东斜坡带的岩性圈闭形成条件.认为研究区的岩性圈闭发育条件明显优于构造圈闭,并且岩性圈闭具有类型少,规模大,储层物性和盖层质量好,受单一沉积因素控制等特征.输导系统以砂体单一输导系统和砂体-断层复合输导系统为主,成藏动力分析结果表明阜东斜坡带岩性圈闭位于优势运移路径上,具备良好的成藏条件.其中阜5井区岩性圈闭成藏条件最好,勘探前景广阔.
Based on the analysis of tectonic setting,sequence stratigraphy and sedimentary system,the forming conditions of the Middle-Upper Jurassic lithologic traps on East Fukang Slope,Jungar Basin are summed up.It is held that the chances for the formation of the lithologic traps are clearly more than that for the tectonic traps in the studied area,and that the lithologic traps are characterized by fewer types,large scale,high-quality reservoir property,high-quality capping condition and single sedimentation-controlling factor.The main passage systems are single sandbody type and sandbody-fault complex type.The analysis of pool-forming dynamic shows that the lithologic traps locate in the superior path of hydrocarbon migration for a long time,and therefore they have superior pool-forming conditions.Of them,the pool-forming conditions of the lithologic traps in Fu 5 well-block are the best.In other words,they have good exploration prospects.
