在系统研究塔里木盆地区域地质构造条件和沉积特征的基础上 ,深入分析了塔里木盆地阿瓦提凹陷石炭系生油岩的分布范围、母质类型、有机质丰度及成熟状况 ,同时结合塔里木盆地近年勘探中取得突破的 5套储盖组合情况 ,认为阿瓦提凹陷主要存在P1h P2s、C P1x两套储盖组合。而阿瓦提凹陷中的阿南断鼻构造带面积大、是凹中隆起 ,构造带上断背斜、断鼻构造发育 ,并且储油层与生油层间有断层勾通 ,容易捕获和聚集油气形成油气藏 ;阿南斜坡区虽然局部构造不发育 ,但处于油气运移的指向 ,也容易捕获和聚集油气形成油气藏。从而得出了阿南断鼻构造带和阿南斜坡区均是阿瓦提凹陷下步油气勘探的重点区带。为该区下步勘探部署提供了依据。
On the basis of systematically studying the regional geological tectonic conditions and sedimentary characteristics in the Tarim Basin, the distribution range, parental types, abundance and maturity of Carboniferous source rocks in the Awati Depression of the Tarim Basin are analyzed in depth. In the meantime, Breakthrough in the five sets of reservoir cover combination that the Awati Depression mainly P1h P2s, C P1x two sets of storage and cover combination. In the Awati depression, Ananan fault nose is large in tectonic belt area with concave uplift, fault zone anomaly and fault nose structure developed. There is a fault between reservoirs and oil reservoirs, which makes it easy to capture and accumulate oil and gas. Although the local structure is not well developed in the southern slope of Anan, it is in the direction of hydrocarbon migration and is also easy to capture and accumulate oil and gas to form oil and gas reservoirs. It is concluded that the Ananan fault zone and the southern slope of Anan slope are the key areas for next exploration of oil and gas in Awati Depression. This area provides the basis for further exploration and deployment.
