测井与井中物探的回顾和展望

LOGGING AND BOREHOLE GEOPHYSICAL PROSPECTING:REVIEW AND PROSPECTS

本文简要地回顾了地矿部系统测井与井中物探近40年来尤其是近10年的发展历程。方法技术方面:采集系统从半自动、全自动模拟记录到数字记录;方法和井下仪器从几种到数十种,并逐步实现了系列化和组合化;刻度技术从无到有。凡此种种,标志着我们已进入数字化阶段。方法应用与软件开发方面:测井已成功地应用于煤田等20多种矿种;井中物探从金属矿扩大到水文、工程和环境地质领域中,并取得了良好的地质效果和经济效益;软件开发从起步到现场操作管理、数据采集、解释成图,以及室内进一步结合CT技术处理、解释、成图成像等。显示出已初步具备了现代钻孔地球物理技术的一些发展特点。最后,对前景作了展望。

Abstract This paper makes a brief review of the development of logging and borehole geophysical prospecting work conducted by various units affiliated to Ministry of Geology and Mineral Resources in the past 40 years, especially in the last 10 years. In methnds and techniques, the collection system has deve- loped from semiautomatic and automatic analog recording to digital recording, the methods and borehole instruments have increased from several sorts to tens of sorts with the gradual realization of seriation and combination, and the graduation technique has growll out of nothing, indicating that our work has entered the stage of digitization. In method application and software development, the logging has successfully extended its application flom coalfi- eld to more than twenty types of ore deposits, the borehole geophysical prospecting has expanded its utilization from metallic deposits to the fields of hydrological engineering and environmental geology and thus yielded good geological effects and economic benefits, and the software development has grown from its first-step work to the in-situ operation and management, data collection, interpretation and mapping as well as indoor further proccessing, interpretation and mapping and imaging in combination with the CT techni- que. All these achievements demonstrate that our work has possessed some characteristics of modern borehole geophysical techniques. finally, the paper predicts the prospects of the work.
