二维地震勘探技术在新疆北塔山煤矿区的应用

Application of two-dimensional seismic exploration technology in Beitashan Coal Mine area of Xinjiang

北塔山煤矿区充分利用二维地震勘探技术,结合测井和钻探成果,通过合成地震记录的标定,确定B3煤层反射波(Tb3)为此次解释的主要标准波,采用地震波阻抗反演技术,对该区煤层露头、可视边界及煤层结构进行了解释,查明了煤层赋存范围、构造形态及F1断层,获得了较好地震勘探资料。

Beitashan Coal Mine area makes full use of two-dimensional seismic exploration technology.Combined with logging and drilling results,through the calibration of synthetic seismic records,it is determined that the reflection wave(Tb3)of No.B3 coal seam is the main standard wave of this interpretation.Using seismic wave impedance inversion technology,the coal seam outcrop,visual boundary and coal seam structure in this area are interpreted,and the coal seam occurrence range,structural form and F1 fault are identified.Good seismic exploration data are obtained.
