余吾 - 古城区块基于测井参数的煤体结构预测

Prediction of Coal Body Structure Based on Well Logging Parameters in Yuwu-Gucheng Block

基于余吾-古城区块3号煤层测井资料与现场取芯结果,在GSI值表征的基础上,通过GSI表征值与测井参数的相关性分析,建立煤体结构GSI表征值的测井解释模型,从而实现通过测井参数对煤体结构的连续精确化表示。结果表明:通过余吾区块测井资料计算的煤体结构GSI值与现场取芯结果相符,说明此预测方法适用于该区块煤体结构判别。

Based on the well logging data and on-site coring results of the No.3 coal seam in Yuwu-Gucheng Block,based on the characterization of GSI value,a well logging interpretation model for the GSI characterization value of coal body structure is established through the correlation analysis between the GSI characterization value and well logging parameters,thus to achieve continuous and accurate representation of coal body structure through well logging parameters.The result shows that the GSI value of coal body structure calculated from well logging data in Yuwu Block is consistent with the result of on-site coring,indicating that this prediction method is suitable for the discrimination of coal body structure in this block.
