本技术报告总结了用于水文地质目的的地球物理钻孔测井的最佳实践。它描述了记录钻孔时需要考虑的因素和需要进行的测量。然而，由于目标、地下水条件和可用技术的巨大差异，可能没有明确的“标准”测井程序。钻孔地球物理测井是一门不断发展的科学，不断采用新的和不同的技术。每个应用程序都会带来一系列问题，可能需要一组特定的日志才能获得最大的信息。因此，本技术报告提供了有关现场实践的信息，目的是了解测量参数的变化如何有助于考虑特定的当地条件。它涉及为划定含水层边界而进行的常规测井类型； 绘制含水层几何图形；评估地下水的化学质量和数量；供水目的；填埋场调查和污染研究；钻孔施工和条件；以及地下岩性信息。 本技术报告中未特别考虑的应用包括矿物和碳氢化合物评估以及岩土工程和结构工程调查。然而，本技术报告可能是任何钻孔地球物理测井工作的一般信息来源。 注:本技术报告仅以一般方式提及测井期间收集的数据解释。有关地球物理测井分析和解释的详细信息，请参考专门的文本。参考书目中包含了此类文本的示例。

This Technical Report is a summary of best practice for those involved in geophysical borehole logging for hydrogeological purposes. It describes the factors that need to be considered and the measurements that are required to be made when logging boreholes. There can, however, be no definite "standard" logging procedure because of great diversity of objectives, ground-water conditions and available technology. Geophysical logging of boreholes is an evolving science, continually adopting new and different techniques. Every application poses a range of problems and is likely to require a particular set of logs to gain maximum information. This Technical Report therefore provides information on field practice with the objective of how variations in measured parameters may be useful to take account of particular local conditions. It deals with the usual types of logging carried out for delineation of aquifer boundaries; mapping aquifer geometry; assessing the chemical quality and quantity of ground water; water-supply purposes; landfill investigations and contamination studies; borehole construction and conditions; and subsurface lithological information. Applications not specifically considered in this Technical Report include mineral and hydrocarbon evaluation and geotechnical and structural engineering investigations. However, this Technical Report may be a source of general information for any borehole geophysical logging effort. NOTE Interpretation of the data collected during logging is referred to in this Technical Report only in a general way. For full details of the analysis and interpretation of geophysical logs, reference should be made to specialized texts. Examples of such texts are included in the Bibliography.
