赵庄区块煤层气井测井解释含气量模型应用研究

Application of Gas Content Logging Interpretation Model of Coalbed Methane Wells in Zhaozhuang Block

确定煤层煤质和含气量是煤层气测井评价的重要内容。从煤层体积模型出发,通过对沁水盆地赵庄区块煤芯实验数据进行统计,结合测井响应特征,提取了与煤质以及含气量相关的测井信息,利用统计回归的方法,建立赵庄区块煤层气井测井解释含气量模型,并通过计算结果验证了模型的合理性,在此基础上,对煤层气储层的煤质及含气量等储层参数进行了实测解释,解释结果也与该区的水文地质条件相符合。该模型为赵庄区块煤层气的勘探开发提供了理论指导。

Determining the coal quality and gas content of coalbed methane is an important content of coalbed methane logging evaluation.Starting from the coal seam volume model,this paper collected the logging information related to coal quality and gas content through statistics of coal core experimental data in Zhaozhuang block of Qinshui Basin combined with logging response characteristics,used statistical regression methods to establish the gas content logging interpretation model of coalbed methane wells in Zhaozhuang block,and verified the rationality of the model through the calculation results.On this basis,the coalbed methane reservoir parameters such as coal quality and gas content was measured and interpreted,and the interpretation results were also consistent with the hydrogeological conditions of the area.This model can provide theoretical guidance for the exploration and development of coalbed methane in Zhaozhuang block.
