桥口地区深层天然气勘探潜力评价

本文阐述了桥口地区的构造格局和构造演化特征。然后在对桥口地区深层天然气成藏的油源、储层、圈闭形成与油气生成运移的配置关系、盖层及保成条件进行深入研究的基础上，利用多因素圈闭法对该区的圈闭进行了综合评价。最后对有利圈闭的勘探潜力进行了分析，并指出了桥口地区下一步深层天然气勘探的目标区。

The Evaluation Of Deep-seated Gas Exploration Potential In Qiaokou Region

This article do a general evaluation to deep-seated gas exploration potential in QiaoKou region. At first, we describe the structure pattern and structure evolvement character. Then based on the study that include the relation between the oil derivation, oil layer, trap building that engender the reservoir and oil form as well as trasferation; cover layer and preservative condition. We used varied factor trap method to make a compositive evaluation to this regoin. At last, we analyse the exploration potential of favorable trap and point out the next step deep-seated gas exploration objective in QiaoKou region.
