摘　　要：沁水煤田位于沁水盆地大型复式向斜的东翼,是我国重要的煤炭存储区域之一,蕴藏着丰富的煤及非常规天然气资源。因此,对该地区的煤系地层研究具有十分重要的现实意义。地震勘探技术是解决非常规天然气评价关键地质要求的有效手段。以研究区内的三分量地震测线K1为例,介绍了三分量地震勘探在该地区的采集效果、处理的关键技术及解释成果。为该地区的地下地质特征以及煤层气以及页岩气资源后续大规模的勘探开发提供了依据。Qinshui coalfield is located in the east wing of the large complex syncline in Qinshui Basin, which is one of the important coalfield storage areas in China. It is rich in coal and unconventional natural gas resources. Therefore, it is of great practical significance for the study of coal-bearing strata in this area. Seismic exploration technology is an effective mean to solve the critical geological requirements of unconventional natural gas evaluation. In this paper, the three-component seismic survey line K1 is taken as an example to introduce the key techniques of collecting and processing and interpretation results of the threecomponent seismic exploration in the area, which provides the basis for the underground geological characteristics of the area and the subsequent large-scale development of coalbed methane and shale gas resources.
