本文利用苏堤区带的地震、钻井、测井、测试和化验分析资料,对该区带进行应力场、古水动力场、储盖结构分析、储层评价等研究,依据圈闭模糊数学综合判别方法对含油气系统进行综合分析,认为:(1)苏堤区带具备了形成大型气田的地质条件。(2)逆断层下盘和始新统平湖组是苏堤区带又一重要勘探领域。(3)春晓气田是苏堤区带寻找大气田的首选目标。

Using data of seismic, drilling, logging, testing and laboratory test, this paper integrates stress field, paleo-hydrodynamics, Reservoir and seal analysis to study petroleum system, the following conclusions are obtained:1. Sudi Play has geological condition of forming large-size gas field.2. Footwall of reversed fault and Eocene Pinghu formation are important exploration fields.3. Chunxiao gas field is the first exploration target in Shudi.
