基于地球物理方法的煤系地层陷落柱识别研究

Study on collapse column identification in coal-bearing formation based on geophysics methods

以五阳煤矿某一采区发现的地质异常体为研究对象,通过运用Geoview进行人工合成地震记录标定,提取瞬时属性以及Opendtect软件进行相干体分析,对陷落柱发育位置及规模进行定量评价,最后通过关键井取心验证,确定该地质异常体为陷落柱。

This paper focused on a geologic abnormal body in one mining area of Wuyang Coal Mine. Using Geoview software to calibrate the horizon by synthetic seismic records, coherence body analysis was also carried out by picking up instantaneous attribution and the u- sing Opendtect software,whose purpose was to determine the location and shape of the geologic abnormal body. At last, through the veri- fication by coring of key well, it was determined that the geologic abnormal body is a collapse column.
