摘要
该文简述了近年来测井技术在煤层气综合地质评价方面的发展状况,煤储层特点,测井响应特征及测井评价方法。以大城煤田为例,总结了大城地区测井资料在划分煤层、计算工业组份、计算含气量、确定煤层及顶底板弹性模量参数等方面的应用,建立了一套利用地球物理测井评价煤层气储层的方法。该文为今后本区煤层气勘探开发,提供了一定的技术参数和施工经验,并对测井资料做更深入的研究和量化煤层气储层的测井特征提出了建议。
In this paper,the development status,characteristics of coal reservoir,characteristics of logging response and logging evaluation methods of logging technology in the comprehensive geological evaluation of coalbed gas in recent years is introduced briefly. Taking the Dacheng coalfield as an example,the applications of logging data in Dacheng area in dividing coal seam,calculating industrial components,calculating gas content,determining the parameters of coal seam and elastic modulus in roof and floor are summarized. The method of evaluating the coalbed gas reservoir is built by using the geophysical logging.This paper provides some technical parameters and construction experience for the exploration and development of coalbed gas in this area,and the further research about logging data made,and some suggestions are put forward for quantification of logging features of coalbed gas reservoir.
