摘要
岐南断阶带紧邻岐口凹陷，油气源充足：明化组下段－馆陶组上段和沙河街组一段－二段两套储盖组合配置良好。圈闭和运移条件成为控制油气聚集的重要因素。不同类型构造圈闭聚集油气的能力不同。地层与断层的组合关系制约着上第三系油气运移方向和富集位置。上第三系油气藏主要沿海1、海4继承性大断层分布。
Qinan fault step belt is just adjacent to Qikou sag and is with rich hydrocarbon sources, where there are two very good reservoir-cap associations of lower part of Minghuazhen formation-upper part of Guantao formation and Shahejie formation Ⅰ - Ⅱ . Trapping and migration are the main controlling factors for hydrocarbon accumulations. The trapping capability varies from one type of structural trap to another. The association of strata and faults control the migration and enrichment of Tertiary hydrocarbon. Upper Tertiary oil/gas accumulations are distributed along Hai 1 and Hai 4 major faults.
