| 摘 要： | 在地质工作调整结构、转换机制过程中,1992年我国固体矿产地球物理工作压缩,航空地球物理工作量减少。但以地震为主的油气地球物理工作量保持近几年水平并略有增长,水文、工程、环境地球物理工作持续发展。1992年我国勘查地球物理取得了较多新的科学技术成果。推出了一批新的地球物理仪器,其中包括高采样率浅层数字地震仪、地下管线探测仪、轻便遥测多道地震仪、工程质量检测仪、高分辨率中子俘获γ能谱测井仪等。航空磁力水平梯度系统投入使用。形成了一批新的功能较强的地震、测井、电法及重磁资料处理解释系统或工作站。新理论新方法研究加强,地学层析成象理论和应用发展迅速,神经网络模式识别方法扩大应用,分形及混沌理论在勘查地球物理中的应用也在起步。深部地壳调查及油气勘查领域地球物理的国际合作进一步扩大。

| Abstract: | Abstract In the process of readjusting structure and changing mechanism in goological work,
mine geophysical work of china was cut down in,1992, and the amount of aerogeophysical
work was also reduced. Nevertheless, the amount of oil-gas geophysical work dominated by
seismic exploration maintained the level of the past few years and even somewhat incre-
ased, and geotechnical and environmental geophysics developed continuously. In 1992, quite a
lot of new technical achievements were gained in exploration geophysics of China, and a
number of new geophysical instruments were developed, which included shallow numerical
seismograph of high sampling rate, portable multichannel telemetering seismograph, civil engi-
neering quality detector, underground pipelline detector, and high resolution-ratio neutron-
capturing gamma power spectral logger. The aeromagnetic horizontal gradient system was put
ioto field application, and a set of new seismic, logging, electrical and gravity and magnetic
processing and interpretation systems or working stations with relatively high functional effi-
ciency were formed. The study of new theories and new methods was intensified, and geoto-
mography and its application developed rapidly, the application of model recognition methods
such as neural net was extended, and progress was also made in the application of fractal and
thaos theory to geopysics. Iaternational cooperation in such geophysical fields as deep crustal
survey and oil-gas exploration was further broadened. |
