葛店煤矿扩大区位于河南省永夏煤田蒋河复式向斜之南端,夹于双庙和王庄两条相向对倾的高角度正断层之间,构造比较复杂。为提高本区地震勘探研究程度,特安排在22线和4线两条地震测线上做虚速度测井的特殊处理工作,其应用效果略述如下。
The Gedian coal mine expansion area is located at the southern end of the Jianghe double syncline in the Yongxia coalfield in Henan Province and is sandwiched between two high-angle normal faults that are oppositely inclined to Shuangmiao and Wangzhuang. The structures are complex. In order to improve the degree of seismic exploration in this area, Special Arrangements are used to do the special treatment of virtual velocity logging on the two seismic lines of line 22 and line 4. The application results are summarized as follows.
