三维叠前深度偏移技术是解决地下构造复杂和速度横向变化问题的一种有效手段。它需要与地质人员和解释人员相结合,了解综合钻井和测井的信息,反复迭代,以逐步建立符合地下实际的速度模型;然后通过计算射线在速度模型中的旅行时间,采用Kirchhoff积分法进行偏移成像。用GeoDepth三维叠前深度偏移处理软件,对东濮凹陷文23南部3D资料进行了叠前深度偏移处理,取得了良好的处理效果。
The 3D prestack depth migration technology is an effective way to solve the problem of complex underground structures and lateral changes in speed. It needs to be integrated with geologists and interpreters to understand the information of integrated drilling and logging and iteratively iteratively to gradually establish velocity models that conform to the actual underground conditions. Kirchhoff’s integral method is then used to calculate the travel time of the ray in the velocity model Offset imaging. By using GeoDepth 3D prestack depth migration software, prestack depth migration is performed on the 3D data of Wen 23 South of Dongpu Depression, and a good treatment effect has been achieved.
