我国勘查地球物理的若干进展──1993年

1993年,我国金属矿地球物理工作继续缩减。航空物探工作量仅及1988年的1/3.油气地球物理工作持续增长,其中陆上三维地震年工作量已超过9000km².水文、工程、环境地球物理市场保持兴旺,推动了有关技术的发展,众多单位不断推出新型号的多功能浅层地震仪式工程检测仪。较少受经费制约的室内计算机处理、解释、模拟、显示方法及软件研究,以及某些理论研究保持前进势头,又有一些引人注意的成果。承担国际市场项目有所增多,但总规模仍然很小。

SOME ADVANCES IN EXPLORATION GEOPHYSICS IN CHINA──1993

in 1993, geophysical exploration work for metallic deposits was forther reduced inChina and the amount of aerogeophysical work was only one third that of 1988. In contrast, theOil and gas geophysical exploration work was still growing, and the annual amount of continentalthree-dimensional seismic excploration exceeded 9000 km2. The hydrologic, enyineering and environmental geophysical exploration market remained prosperous, which promoted the developent ofrelevant techniques. New types of multi-functional shallow seismographs or engineering detectorswere unceasingly desired by many units. In-house computer processing, interprotation, simulation, display and software researches which were less subject to the restriction of fials as wellas some theoretical studies remained in progress and, as a result,some remarkable achievementswere gained. The international market projects undertaken by China increased to some extent;nevertheless, the total amount of work in this aspect remained very limited.
