摘要
沾化凹陷缓坡带是隐蔽油气藏发育的有利区带 ,也是继凸起、潜山之后的重点勘探区带。缓坡带是该凹陷沙四、沙三段烃源岩生成油气的运移指向 ;断层、裂缝、不整合面和储层是缓坡带油气运移的主要通道。在缓坡带油气运移方式分析的基础上 ,建立了相应的成藏模式 ,并讨论了缓坡带油藏的形成与分布特点。
The gentle slope belt in Zhanhua sag is one of the favorable regions that develops subtle reservoirs, and is important exploration area besides arch and buried hill. It is the main migration direction of hydrocarbon generated in Es 3 and Es 4 of Zhanhua sag. The fault, fracture, unconformable surface and reservoir are the major channels of hydrocarbon migration in gentle slope belt. Based on the analysis of hydrocarbon migration modes, the reservoirs forming mode is built up, then the characters of forming and distribution of the oil reservoirs in gentle slope belt are discussed.
