摘要
济阳坳陷是一个典型的陆相断陷湖盆 ,油藏特征非常具有代表性。从埋藏层位、油藏类型、原油性质、产能特征、增长历史、品位变化等方面 ,较全面地论述已探明石油地质储量的分布规律和基本特点。分析表明 :济阳坳陷的构造格局及沉积特征控制了油藏的分布和富集程度 ,各类油藏中以砂岩构造油藏生产性质较好。经过近 40年的勘探 ,济阳坳陷在经历了储量增长高峰期之后 ,目前已逐步进入以寻找中、小型复杂隐蔽岩性及构造油藏为主的勘探阶段 ,储量平稳增长 ,探明储量品位总体呈现出规律性下降趋势。图 5参
The characteristics of OOIP in Jiyang depression, a non marine fault basin, are very representative. From the analysis of buried horizon, pool type, crude oil nature, production performance, reserves increase history and quality change, we know that pool distribution and enrichment have been controlled by the structure and sediment in Jiyang depression, and that the production performance of sandstone structural oil reservoirs is much better in all kinds of oil reservoirs. After the exploration of about 40 years, Jiyang depression has experienced peak reserves increase and stepped into such a present stage as mainly looking for medium and small sized subtle complex lithologic pools and structural pools, oil reserves increasing steadily and proven oil reserve quality having a tendency to decrease totally.
