东海西湖凹陷苏堤区带大中型气田目标评价

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。

Prospect Assessment of Large-medium Size Gas Field in Sudi Play of the Xihu Trough, the East China Sea

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.
