地球物理测井在水文地质勘察中的应用综述

全世界的水资源日益匮乏使得各个国家都不断地加大水文地质勘察力度，以便对地下水资源进行合理的开发、评价和保护。地球物理测井可以在水文钻孔中获得丰富的物性和位场信息，所以它已经成为一种十分重要的水文地质勘察手段。现在地球物理测井包含有几十种不同物理原理的井下测量方法．而且各种方法每年都在不断地发展改进并不断有新的方法出现，所以很有必要对过去这螳年水文测井方法的发展做一个总结。通过对国内外这些年水文测井研究与应用工作的分析总结，可以充分了解应用于水文地质勘察的各种测井仪器与方法的发展过程，进而对各种水文测井方法的应用原理进行分类总结，然后根据国内外水文测井工作的实例分析不同地质环境中水文地质单元的测井响应特征，同时总结各水文测井方法适用于解决哪些具体问题。这样就可以为我国今后的水文测井研究和水文地质勘察工作提供一些有用的参考和帮助。

OVERVIEW OF THE APPLICATION OF GEOPHYSICAL WELL LOGGING IN HYDROGEOLOGIC SURVEY

Because of the continuous shrink of water resources all over the world, lots of countries enhanced their hydrologic survey for a reasonable exploitation, estimate and protection of underground water. Well logging could obtain plenty of information of lithology and geophysical fields in boreholes conveniently, so it has become a very important means of hydrogeologic survey. Because there are more than 25 kinds of well logging methods, all these methods are being improved year by year and new methods are always presented continually, it is required to summarize the development of hydrogeological well logging in recent years. Analyzing and concluding the global research and application of hydrogeological well logging in the past, we could understand the development of well logging instruments and methods used in universal hydrogeological survey; then classify all the logging methods by their application principle; at last, analyze the logging responses of different logs on different hytrogeological units and conclude what kind of problems a logging method can solve reasonably. In this way, we can foresee the direction and prospect of their development. Meanwhile, we can provide some useful references and assistance for the coming hydrogeologic survey in our state.
