我国勘查地球物理的若干进展—1989年

    THE ADVANCES IN EXPLORATION GEOPHYSICS IN CHINA-1989

    • 摘要: 我国有一支约18万人的勘查地球物理队伍,其工作规模居世界前列,每年取得大量应用成果和研究成果。中国地质学会勘探地球物理专业委员会将每年编写一篇综述,报导前一年我国勘查地球物理的若干主要进展。本文是第一篇。它按航空和海洋地球物理、地震、地球物理测井和地下地球物理、地面电法、地面重力和磁法、地面γ能谱等分别加以叙述。它提供了我国航空地球物理和地震去年的工作队数和完成的工作量,以后也将每年报导这些数字和其它一些统计数字。它报导了去年我国一些主要地球物理方法的技术和应用的进展,但不覆盖所有的地球物理方法和应用领域。资料说明地震始终是我国最主要的地球物理方法,在油气勘查以外的领域中它的重要性也在继续增大,并取得迅速的技术进展。电磁法正受到我国物探工作者更大的重视。本文第一部分还报导了我国勘查地球物理队伍的某些基本情况和统计数字。

       

      Abstract: With a contingent of 180,000 exploration geophysicists, China’s geophysical prospecting work occupies the forefront place in scale in the world and,as a result, large quantities of applied and research outcomes are being obtained every year. From cow oa, the Commission on Exploration Geophysics, Geological Society of China will write a review every year to report some major advances in exploration geophysics in the previous year,and this paper is the first one. It describes such subjects as aerogeophysics and oceanogeophysics, seism,geophysical logging and underground geophysics, ground electromagnetic method,*ground gravity and magnetic method, and ground gamma ennrgy spectra, and provides the number of field parties which were engaged in aerogeophysical and seismic exploration last year and the amount of work that was completed. Such data and some other statistical data are to be published every year.The paper also reports advances in techniques and applications of some major geophysical methods, but does not cover all the geophysical methods and their applications. Data show that seismic prospecting has been all along the most important geophysical method in China, whose significance is continuously increasing in other fields besides oil-gas exploration and whose techniques have made rapid progress. More and more importance is being attached to electromagnetic method by geophysicists in China. In the first part of this paper some present basic conditions of the exploration geophysical contingent are discussed with some statistical date given.
