摘要： 断层气探测方法是活动断层探测中常用的一种方法。 实践证明, 这种方法在浅覆盖地区活动断层初勘阶段是有效的。 但在第四系厚覆盖地区开展活断层探测, 断层气方法是否有效或怎样做有助于提高该方法的有效性, 是本文要阐述的问题。 本文利用天津地区断层气实测的丰富资料, 并与人工地震、 钻孔勘探、 样品年代学测定资料进行对比分析, 论证了断层气方法在深隐伏活断层空间位置、 断层活动性判定和断层分段中的有效性。 并依据实际工作经验, 给出了提高断层气方法在活断层探测中有效性的技术途径。

Abstract: The measure of fault gas is a commonly used method for detecting active faults. Practice has proved that this method is effective on the initial period of detecting active faults in shallow coverage areas. This paper is to explain the problem of how to improve the effectiveness of the method in deep. Based on the plentiful factual measured data of fault gas in Tianjin area, and by contrasting and analyzing the artificial seismic method and the drilling and the chronological dating,we elaborated on the effectiveness of fault gas method from three aspects of active buried faults location,fault activity and fault segmentation. Based on actual work experience, the authors put porward the effective technical approachs of how to improve the methods of fault gas using for detecting active faults.

Key words: Buried fault, Fault gas methods, Technical approach
