摘　　要：在已勘探多年的留西地区,遵循新的研究思路和工作方法,即"构造研究找背景、层序划分建(地层对比)格架、微相研究定(砂体)类型、成岩分析划(经济)界线、储层预测描砂体、综合分析建(成藏)模式、圈闭优选标井位、滚动研究扩成果",开展Es3低位体系域辫状河三角洲砂体岩性油藏勘探取得了重要突破,控制、预测两级石油地质储量达5000×104t。In Liuxi area where exploration has been explored for decades, new research conceptions and methods are adopted, such as 'structural study focusing on background, division of sequences for establishment of configuration (for comparison of formations), study of microfacies for determination of types (of sandbody), diagenetic analysis for determination of (economic) boundaries, reservoir prediction for description of sandbody, integrated analysis for establishment of reservoir model, optimization of traps for determination of well position, and progressive study for more results. Important breakthroughs are made in exploration of lithologic oil reservoirs of braided delta sandbody in Es3 low stand systems tracts. The controlled and predicted reserves reach 50 million tons.
