摘　　要：以寿阳地区HZ区块煤层气测井为例,介绍了该区地层岩性、物性特征测井方法:根据钻孔测井响应值,确定了该区煤层气储层深度、厚度和结构,并使用体积模型方法及岩心刻度测井法计算了该区目的煤层的相关工业分析指标;利用原始状态下测井资料计算岩石力学性质,获得了比实验室岩石测试更具有代表性的力学参数;利用该区两个参数井的测试资料,建立了该区煤层含气量与灰分的线性相关关系;利用双侧向测井曲线上正幅度差异程度,评价其岩煤层裂隙的发育程度及渗透性;应用声幅测井和声波变密度测井资料进行固井质量评价,准确地判定了该区钻孔第一、二界面的胶结质量。通过该区煤层气测井技术的应用,认为在煤层气测井中可不考虑微球形聚焦测井。To take the CBM well logging in HZ block, Shouyang area as an example, introduced strata lithology, physical property features and logging method. Based on borehole logging response value, determined CBM reservoir depth, thickness and configuration in the area; computed dependent proximate analysis indices of the target coal seams through volume model method and rock core calibration logging method. Computing rock mechanical properties by the use of logging data under original state obtained mechanical parameters more representative than those of laboratory rock tested results. To use tested results of two parameter wells in the area, established linear dependency relation between coal seam gas content and ash content. To use positive amplitude difference on dual lateral logging traces assessed fracture development degree and permeability of rock and coal. To use acoustic amplitude logging and acoustic variable density logging data carried out cementing quality assessment, determined cementing quality of first and second interfaces of boreholes in the area correctly. Through the application of CBM well logging technologies in the area, we considered that the microspherically focused logging can be left out of account.
