阳-茌聚煤区钻探勘查中地层对比研究

Study on stratigraphic correlation of drilling exploration in Yang-Chi coal-bearing region

煤层对比是煤田地质勘探中研究煤层分布情况、稳定程度和空间变化规律等特征的最常用手段之一。综合利用岩性、厚度、间距等多种方法对阳-茌聚煤区煤系地层进行了精准识别和对比分析,并归纳总结了研究区煤系地层识别的主要步骤。研究成果解决了因层位不清而造成的盲目取芯及不停提下钻的问题,为远景规划区和类似勘查区现场地层识别工作提供了依据。

Coal seam correlation is one of the most commonly used methods to study the distribution,stability and spatial variation of coal seams in coal geological exploration.By means of lithology,thickness,spacing and other methods,the coal measures were precisely identified by correlation analysis in Yang-Chi Coalfield,and the main steps in the research area of coal bearing strata identification were summarized.The research results not only solved the blind core and consistent drilling automation problem,but also provided the basis for planning area and similar area site exploration strata identification.
