蔡寺—白沙普查区煤岩层对比分析

Comparison and Analysis on Coal-rock Seam in Caisi-baisha Prospecting Area

分析了普查区的地层层序,根据其岩性组合特征及物理特性,综合运用标志层法、层间距法、煤岩层组合特征对比法、测井曲线对比法、地震反射波追踪法、煤质特征对比法对区内煤岩层进行了地层划分、煤层对比,并对煤岩层对比分析方法及结果进行了综合评价。实践表明:上述方法的分析结果可作为地层划分、煤层对比的重要依据。

analyzed the stratigraphic sequence of the census area,and based on its lithological combination and physical properties,the marker bed method,layer spacing method,contrast method of coal strata combination characteristics,well-logging curve contrast method,seismic reflection wave tracing method,contrast method of coal quality characteristics were used for stratigraphic classification and coal bed comparison of coal strata in the area.The article also made an estimate of methods and results of coal-rock seam′s analysing.Practice showed that,results of above methods were important basis for stratigraphic classification and coal strata comparison.
