摘要:
高邮凹陷阜三段(E1 f3)是江苏油田复杂小断块油藏勘探的主要领域,也是隐蔽油藏拓展的重要阵地。基于岩心观察,结合粒度和电测曲线特征分析等,开展高邮凹陷E1 f3沉积微相、砂体展布特征与规律研究,总结控砂模式,提出高邮凹陷E1 f3发育河流作用控制的水下分流河道、河口坝和水下分流河道间湾,湖浪作用控制的滩砂、坝砂,以及陡坡带重力滑塌控制的近岸水下扇水道等3类6种沉积微相。物源条件、动力机制和构造格局共同控制了沉积微相及砂体展布,形成斜坡带控砂和断裂带控砂两类模式;斜坡带发育河流控砂和湖浪控砂两种模式,断裂带发育断坡控砂和陡坡控砂两种模式。E1 f3砂体展布及控砂机制分析为高邮凹陷E1 f3隐蔽型油气藏勘探指出方向,为资源接替奠定了基础。
Abstract:
The Gaoyou Sag’s third member of the Funing Formation (E1 f3) is the main field for the exploration of Jiangsu Oilfield’s complicated and small fault-block reservoirs,as well as an essential position for the extension of subtle reservoirs. It was investigated on the sedimentary microfacies,sandbody distribution features,and laws of E1 f3 in Gaoyou Sag and its sand control model was summarized,based on core observations,combined with analysis of grain size and electrical curve characteristics,etc. It is proposed that in E1 f3 of Gaoyou Sag,there are 3 types and 6 kinds of sedimentary microfacies developed,including underwater distributary channel,mouth bar,and underwater distributary channel bays controlled by fluvial action,beach sandbody and bar sandbody controlled by lake wave action,and nearshore underwater fan channels controlled by gravity slump in the steep slope zone,etc. The distribution of sedimentary microfacies and sandbodies is concurrently controlled by provenance circumstances,dynamic mechanisms,and tectonic patterns,generating two types of sand-controlling modes in slope zones and fault belts. In the slope zone,there are two types of sand control by rivers and waves,and two modes of sand control by faults and slopes in the fault zone. The analysis of E1 f3 sandbody distribution characteristics and sand-controlling mechanism lays the foundation for the exploration of E1 f3 subtle reservoirs in Gaoyou Sag.
