| 摘 要： | 新疆准东煤田主要煤层为赋存于中侏罗系西山窑组地层中的B煤组煤层,受区域构造和沉积环境的影响,该煤组煤层存在分叉合并、露头、缺失、火烧等地质现象,煤层结构比较复杂。以准东煤田西山窑组地层中的B煤组煤层为例,介绍了上述地质现象在地震时间剖面上的表现特征及解释原则,并采用地震反演技术对该区煤层厚度及煤层结构进行了解释,其精度与实际揭露相比,吻合程度较高。

| Abstract: | Main coal seams in the eastern Junggar coalfield, Xinjiang are in the B coal group, Middle Jurassic Xishanyao Formation. Dependent upon regional structures and sedimentary environments, coal seam bifurcating and merging, outcropping, hiatus, combustion and other geological phenomena are existed, texture of coal seam is rather complex. Through examples introduced above mentioned geological phenomena of coal seams in B coal group representative characteristics on seismic time sections and their interpretation principles, then interpreted coal seam thickness and texture in the area through seismic inversion technology. Compared interpretation results with actually revealed coal seams showing the coincident degree is rather high. |
