摘要
针对井间反射波资料的特点,采用克希霍夫积分法进行井间资料叠前深度偏移成像。讨论了对井间上、下行波场进行叠前深度偏移成像的一些技术细节和难点,以及井间叠前深度偏移成像处理中涉及的层析成像速度反演、波场分离等技术,并分析了井间反射波偏移成像的有效范围。最后通过模型试算,验证了方法的可行性,并取得了较好的成像效果。
Data obtained irom seismic crosshole prospecting have abundance wavefield information. Cross-well seismic data processing involves in technique of first break picking, tomography, wave field separation and migration, etc. Aimed to the characteristic of cross-well reflection seismic data, Kirchhoff integral method has been used to perform cross-well seismic data pre-stack migration. Some technique details and difficulties, such as tomography velocity inversion and wave field separation, are discussed and also analyzed the effective area of reflection migration. Modeling computation proves the feasibility of the migration method and good effect on image respectively.
