IDENTIFICATION AND DEVELOPMENT MECHANISM OF MINOR FAULTS IN PETROLEUM BASINS: A Case Study of Jiangjiadian Area in Huimin Sag
-
摘要:
在传统地震剖面精细解释的基础之上通过方法创新和蚂蚁体技术应用，总结出了江家店地区小断层的识别特征以及小断层的发育规律.通过江家店地区构造平衡剖面恢复工作，对小断层形成控制因素以及形成时期有了新的认识.通过构造物理模拟实验对江家店小断层的形成机理进行了进一步的验证.在江家店油田小断层的识别过程中，运用上述方法识别出了许多常规地震解释难以识别的小断层，并取得较好的应用效果.
Abstract:Based on the traditional fine interpretation of seismic profiles, the recognition features and development rules of minor faults in Jiangjiadian area of Huimin Sag are summarized through method innovation and ant algorithm application. The restoration of balanced section contributes to a new understanding about the controlling factors of formation and forming period of minor faults. The formation mechanism is further verified by structure physical modeling. Many minor faults difficult to recognize by conventional seismic interpretation are identified by the above method during the process, and good application results are achieved.
