| 摘 要： | 根据永新地区的测井资料和地质特点,设计了有利于该地区井间反射波成像的观测系统。采用最小平方共轭梯度法进行速度层析反演,得到井间反射波成像的速度模型,利用VSP CDP成像与克希霍夫偏移相结合的方法对井间地震上行反射波进行精细成像。井间反射波成像剖面反映了丰富的层间信息,解决了该对井间存在的油水关系矛盾。

| Abstract: | Designed the observation system which is suitable for the reflection wave imaging in this field according to the log information and geologic features in Yongxin field.The velocity tomography inversion was done by least square conjugate gradient method and the velocity model of the crosswell reflective wave imaging was obtained.The fine profile of the upgoing wave was got by the combination of the VSP CDP imaging and Kirchhoff migration.The rich layer information was reflected on the crosswell profile,and t... |
