活动断层探测中断层气真、假异常判别方法
A Method of Distinguishing True and False Anomaly of Fault Gas in Active Faults Survey
摘要
Abstract
In the process of active faults detection, outliers may relate to the contaminated point, or may be due to the fault gas produced in the fault activity, and thus there is true and false anomaly. The paper determines the target fault by analyzing the seismic data and the geophysical data, and uses a grid wiring detection methods along the perpendicular direction to the faults. The paper firstly draws the content curve of each measuring line to determine the location of anomalies, and then draws the isoline graph of content to judge the distribution trends of outliers. If there existed the abnormal belt, and the abnormal belt strike is consistent with fault strike, then the anomaly is caused by fault gas. The paper does the interpretation by combining the content graph and isoline map, which provides a new method for fault anomaly explaining.关键词
