摘　　要：本文针对贵州煤层多、薄和电性特征复杂的特点,利用偶极子阵列声波测井、地层倾角测井结合常规技术开展区域煤层气测井地质、工程应用的综合评价研究,从盖层条件、构造发育情况、煤心基础实验、测井资料、试气试采等方面进行了综合分析,确定了煤层气储层岩石物理参数、应力大小和方向,地层倾角等地质和工程参数,利用岩石机械特性参数开展应力分析、岩石强度分析、压裂设计、水力压裂裂缝高度预测、指导水平井布井。建立了一套适合区域煤层气的偶极子声波测井评价标准和方法,为煤层气后续开发和压裂施工提供依据。The CBM in Guizhou has the characteristics of shallow, thin and complex electrical, so the dipole array acoustic logging, dip logging combined with conventional techniques can be applied into the comprehensive evaluation of regional CBM logging, geology and engineering applications. A comprehen- sive analysis has been made in this article from the caprock conditions, structural development, coal core experiments, logging data and gas test etc, and the CBM reservoir physical parameters, the size and di- rection of stress, dip angle and other geologic and engineering parameters has been determined. Stress a- nalysis, rock strength analysis, design of fracture, prediction of height and horizontal of hydraulic frac- ture, design of well and other studies can be carried out by the parameters of rock mechanical properties. A set of evaluation criteria and methods for dipole acoustic logging for regional CBM has been estab- lished, which can provides basis for subsequent development and fracturing of CBM..
