南方地区开展地震工作的一点想法
|
摘要
针对南方地区地下地质情况以及地表工作条件,提出了四条建议:选择合理模式,强化各个环节,突出速度场研究,综合利用其它非地震信息。重点讨论了基于模型的数据处理和处理解释一体化,先叠加后偏移,在当前计算机能力不足的情况下实现全深度偏移功能;基于模型处理的另一途径是速度层替换技术。
To counter the subsurface geological settings and surface working conditions, four point of suggetion are proposed as following: selecting a reasonable modle, strengthening every link, projecting ve- locity field study and comprehensively utilizing other non-seismic information. Based on the modle pro- cessing, two operable ways have been emphasized, i. e, (1) integrating data processing with interpreaing and making the stack processing before the migration function, especially in our case of limited computer capac- ity, (2) velocity layer substituting in order to make the seismic data imaging perfictly.
