摘要
四川东部地区地形起伏剧烈、地腹构造复杂,给地震资料的处理成像造成了很大的困难。在全面分析该区地质、地震情况的基础上,提出了从野外地质到室内地震资料解释、处理一体化的地震资料成像研究思路,并针对静校正、速度场的建立及偏移成像作了细致的研究,研究成果在对西山构造地震老资料重新处理中见到明显效果,为复杂构造地震资料的成像积累了经验。
It is difficult to process seismic-data imaging due to violent relief topography and complex subsurface structure in eastern Sichuan Basin. Based on its geological and seismic conditions,we proposed a research thought which is from field geology to in-door seismic-data interpretation,and to seismic-data integrated imaging. Simultaneously,detailed studies have been done for static correction,establishment of velocity field and offset imaging. And an obvious effect is gained in reinterpretation of old seismic data of Xishan structure. And the research provides the experiences on imaging in complex structure.
