摘要
本文指出丁在渤海湾盆地深部油气勘探中所遇到的问题。基于对沉积体系、烃源岩、储集层、次生孔缝、油气运移和保存、圈闭及油气藏类型的分析,得出了油气富集的规律。结合储量计算,本文介绍了一种深部储集层经济下限评价的新方法,这种方法能较好地运用于大多数油田。文章最后对深部勘探开发工作提出了几点建议。
This paper point out the problems encountered in deep exploration in the Bohai Bay Basin. Based on analyzing the depositional systems, source rocks, reservoirs, secondary porosity and fractures, migration and preservation, traps and accumulation types, this paper describes the regularity of hydrocarbon enrichment. Associated with the reserve calculation, a new method of evaluating the economic low limit of reservoirs in the deep earth has been proposed in this paper and can be well applied to most oil field. At the end of the paper, some suggestions about exploration and development for the deep formations are presented.
