Grasp of the world geophysical technology development status,to promote seismic data processing and interpretation of technological progress

第82届SEG年会成果表明:计算机技术和地震装备技术的发展,引领了国际地球物理勘探技术的快速发展;宽方位、宽频带、高密度等采集技术,各向异性逆时偏移、弹性波的全波形反演等处理技术,多波处理与解释、4D地震等技术,很快将成为物探的主导技术.为了更好地把握技术的发展,需要在地震资料处理、解释领域重点开展如下研究:发展宽频带、各向异性、最小二乘、弹性波的逆时偏移技术;层析、逆时偏移角度域道集速度分析、全波形反演的速度估计方法、是进一步提高成像精度重点发展方向.岩石物理是地震解释、储层反演、裂缝检测的基础,重点深化在实验室测量、弹性各向异性的测量、油藏描述和监测方向的研究.全波形反演技术是高精度成像建立速度模型和油藏描述重要手段,在理论上、在应用上仍是下一步发展的重要方向.

The 82th SEG annual meeting results show that the computer technology and the seismic equipment technology development, leading the international geophysical prospecting technology fast development; Wide azimuth, broadband, high density and acquisition technology, anisotropic reverse-time migration, elastic wave full waveform inversion processing technology, wave processing and interpretation, 4D seismic interpretation technology, will soon become the dominant geophysical technology. In order to better grasp the technology development, the need to be in seismic data processing and interpretation in the key areas of research., development of broadband, anisotropy, least squares, elastic wave reverse-time migration technology; Chromatography, reverse- time migration Angle domain word set velocity analysis, full waveform inversion speed estimation method, is to further improve the imaging accuracy key development direction. Rock physics is the foundation of seismic interpretation, reservoir inversion and Fracture detection, the key to deepen in the laboratory measurement, elastic anisotropic measurement, reservoir description and monitoring of the direction of the research. Full waveform inversion technique is a very important means for high precision imaging establish velocity model and reservoir description, in theory and in application is still the important direction of the next step.
