摘要
随着煤层气资源开发规模的增大,实验室煤样解析吸附测试难以满足煤层气区块的测试需求。而测井资料中的体积密度、补偿中子、声波时差、自然伽玛等物性参数与煤层含气量及工业组分存在相关性,可以用于计算煤层含气量及工业组分。文章通过研究安徽宿州南部地区实验室煤样测试资料及相关井孔测井数据,利用多元线性回归法,建立了宿南地区煤层含气量及工业组分的计算模型,为该区煤层气含量及工业组分评价提供了可供参考的测井计算方法。
with the development of CBM resources,the analytical adsorption test of coal sample in laboratory can not meet the test demand of coalbed methane block.The physical property parameters such as volume density,compensated neutron,acoustic time difference and natural gamma in logging data are correlated with coal-bed gas content and industrial components.Based on the study of laboratory test data and well logging data in Sunan area,the paper establishes a calculation model of coalbed gas content and industrial composition in Sunan area by using multiple linear regression method,which provides a reference logging calculation method for the evaluation of coal seam gas content and industrial components in the area.
