我国勘查地球物理的若干进展—1995年

SOME ADVANCES IN EXPLORATION GEOPHYSICS IN CHINA

１９９５年是我国第八个五年计划最后一年。在过去五年中，我国油气地球物理工作稳步增长。三维地震、储层描述和横向预测地球物理技术有长足进展，三维地震叠前深度偏移处理等前沿技术已获应用，直接找油气地球物理技术受到进一步重视，非线性反演及粘弹性、双相、各向异性介质中波传播有关问题成为研究热点。非能源矿产地球物理工作始终处于低谷，但有关技术发展并未停顿。瞬变电磁等方法已基本形成我国自己软硬件配套系统，分布式多道同步电磁采集系统及综合电法工作站等已有可喜成果。对工程和环境地球物理工作日益增长的市场需求带动了有关地球物理技术的发展，但需要系统性重点研究项目的导向和支持。

was the last year of China's Eighth Five-Year Plan.Over the past five years,oil and gas geophysical work has developed steadily;techniques such as three-dimensional seism,reservoir description and transverse prediction geophysics have made considerable progress;three-dimensional seismic pre-stack depth offset processing has begun its application;more importance has been attached to direct oil and gas goophysical prospecting technology; some problems such as nonlinear inversion,viscosity and elasticity,double phase and anisotropic media have become focuses of the research.Geophysical work on solid resources has not yet got itself out of the depression;nevertheless,the related techniques remain in progress Our own sofware and hardware system attached to transient electromagnetic method has been basically formed, and gratifying achievements have been acquired in the aspects of distributive type multichannel synchronous electromagnetic system and processing- interpretation working station of integrated electrical method.The increasing market demands for engineering and environmental geophysics have promoted the development of shallow geophysical technique,which,however,still needs the guidance and support from systematic key research projects.
