基于常规测井资料的煤储层综合评价技术研究

Study on Comprehensive Evaluation of Coal Reservoir Based on Conventional Logging Data

煤储层具有很强的非均质性,准确地把握煤岩特征对后期的开发至关重要。基于鄂尔多斯盆地韩城地区常规测井资料,结合煤岩岩芯测试资料,在对煤岩工业组分定量评价的基础上,运用线性回归法建立经验公式以及相应的测井解释方程,对煤岩的显微组分、工业组分、含气量等进行了定量计算。

Coal reservoir has strong heterogeneity, and it is very important to grasp the characteristics of coal rock.Based on conventional logging data in Hancheng area of Ordos basin, combined with the test data of coal rock core,on the basis of quantitative evaluation of coal and rock industry, using linear regression method to establish empirical formula and the corresponding log interpretation equation, the quantitative calculation of the micro components, industrial components, gas content and so on.
