地震多元参数综合解释煤层结构

STRUCTURE INTERPRETATION OF COAL BEDS USING MULTIPLE SEISMIC PARAMETERS

摘要: 利用时间域和频率域的多元地震参数解释煤层结构属于岩性地震勘探范畴。将该技术用于陕北大保当勘探区,配合地质研究,成功地确定了2^-2煤层的结构变化情况,确定的煤层分叉线同单纯依靠地震解释或地质推断的煤层分叉线比较,精度明显提高。

Abstract: structure interpretation of coal beds using multiple seismic parameters in time domain and in frequency domain belongs in lithologic seismic explorations.Combining with other geological data,this method which used in Dabaodang region,Shaansi province has successfully resolved the structural variation of second coal bed.It has higher precision than normal seismic and geological interpretating methods in discriminating and locating the split phenomenon of coal beds.
