摘要
本文通过对冀中地区第三系油气藏特点的讨论,认为该地区下第三系以复合型油气藏为主,初步提出该类型油气藏的形成机制和分类,论述了河流相砂体是形成复合型油气藏的重要因素。断层是形成复合油气藏的先决条件。通过对岔河集油田的简单分析,阐述了岔河集油田不同断块油气富集程度不同、油藏类型不同的主要原因,并提出了岔河集油田的扩边挖潜方向。
This paper discusses the features of the tertiary petroleum reservoirs,Ji- zhong area and suggests that hybrid reservoir is a main type.Classification and the mechanism of formation of such reservoir are suggested preliminarily. This paper demonstrates that fluvial sand bodies are the main factor in the formation of this type of reservoir and faulting is responsible for its formation. A brief presentation on the geology of Chaheji oil field demonstrates the main cause why there are various types of reservoirs with different reserves in diffe- rent fault blocks in this field,and suggestions on farther extension drillings are presented.
