基于STA/LTA方法的微地震事件自动识别技术
Automatic identification technology of microseismic event based on STA/LTA algorithm
摘要
Abstract
How to quickly and accurately extract microseismic event from the microseismic monitoring data. It is the key issues of micro seismic monitoring technology. The paper presented detailed analysis of the feasibility of the STA/LTA method based on the simulation data, selected a long window length, the ratio of the long window length vs short window length, threshold and other important parameters. Then field data were used to validate the method, re-sults show that the method can quickly and accurately and automatically identify microseismic event from a large number of microseismic monitoring data, and remove the redundant information, thus significantly reducing the amount of data transmission. It makes the ground wireless real-time transmission of microseismic monitoring data possible,and also reduces data storage disk space required,and the good application results were obtained.关键词
