地震资料二次处理解释及其应用

Interpretation and application of the secondary processing of seismic data

产生于地表附近的下行波,经地震界面反射或折射上行至地表被接收后,其地震特征受到了地下介质的改造.地震记录上携带有大量有关地层、岩性和构造的地质信息.在讨论计算机处理复杂地震资料算法实现的可能性的基础上,重点对层析静校正,叠前时间偏移,相干体技术,地震反演、全三维解释以及复杂条件下地质信息显示成像与解释反演等进行论述,阐明利用这些方法、技术对地震资料进行二次处理和解释,能提高地震信息利用率.

Through the seismic interface reflection or refraction, the downgoing wave which generates near earth surface comes up to the surface and is received. The attributes of seismic are remodeled by the below-ground medium, and seismic recording involves abundant of geological information as stratum, configuration and conformation. Based on the possibility of the complicated seismic processing technique algorithm, the paper discussing the static correction tomography, time migration before stack, technique of coherence, seismic inversion, full three dimensional interpretation , the display and interpretation of the complex information of geognosy. By using these technique and method for the secondary treating and interpretation of the seismic data, the utitization rate of seismic data is enhanced.
