黔北煤田测井中煤层的沉积序列编号解释对比方法及应用

摘要

以黔北煤田习水县双龙井田物探测井的应用为例,利用已知煤层或目的层,采用地质界线特征法、地质标志层特征法、煤层序列解释特征法、煤层层间距比较特征法等,对单条或多条物性参数曲线所表现的测井异常特征进行对比分析,总结煤层判定及煤层沉积序列编号的常用解释方法及经验,从而确定煤炭资源储量.%With geophysical logging applied at Shuanglong well field of Xishui County in the Qianbei coalfield as an example and by utilizing known coal seams or beds of interest and adopting such methods as geological boundary characteristic method, geological marked bed characteristic method, coal seam sequence interpretation characteristic method and coal seam inter-layer distance comparison characteristic method, the authors made a comparative analysis of logging anomaly characteristics revealed along a single curve or multiple curves of physical parameters and summed up common interpretation methods and experience obtained in coal seam judgment and coal seam sedimentary sequence numbering so as to determine coal resource reserves.
