摘　　要：本文介绍的断层自动解释流程,是模仿蚂蚁觅食的方法从非常混乱的数据体中根据断层属性来生成断层面。这种新颖的断层解释方法较传统断层解释方法省时、省力,且在解释初期就能客观、全面地给解释人员一个完整断裂系统的概况,文中给出了具体实现的主要步骤。通过在平湖油田放鹤亭构造断层解释中的应用,总结出每个步聚的适用参数,在目的区描绘出一条"Y"字型低级序断层,有效地解决了该区油气开发动态出现的矛盾。By simulating ant foraging method and based on the fault attributes, the fault surface can be generated from disorder data volume in the fault automatic interpretation flowchart which was introduced in this paper. The novel algorithm takes less time and efforts than the traditional fault interpretation methods, and it can provide the interpreters with a basic cognition for the complete fault system in the initial period of the fault interpretation process, the exact steps to realize the algorithm were introduced in this paper, the suitable parameters in each step were summarized through the application of the new method in fault interpretation for Fangheting structure in Pinghu Oilfield, in the target zone, a Y shape low grade fault was delineated, the contradiction with the production performance in this area was effectively solved.
