| 摘 要： | 相干体技术是利用三维数据体来比较局部地震波形的相似性,相干值较低的点与反射波波形不连续性相关。对相干数据体作水平切片图,可揭示断层、岩性体边缘、陷落柱、不整合等地质现象。以山西省某三维地震数据体为例,利用Geoframe软件计算相关体,借以解决煤田地质勘探中识别小断层和陷落柱等地质问题。

| Abstract: | The coherent body technique is used to compare similarity of local seismic wave forms,where the coherent value is low,usually related to the reflection wave form discontinuity.The time slice of coherent data body can unveil geological phenomena of fault,rock body margin,subsided column and unconformity.Took a 3D seismic data body in Shanxi as example,used the Geoframe software to calculate coherent body,the geological problems of minor fault and subsided column in coal geological exploration were settled. |
