摘要
雁木西地区三维地震速度存在着纵横向变化剧烈、系统误差及局部谱点异常等问题,对于工区内低幅度构造的勘探造成了一定的难度与障碍。经对该区已知井点速度拟合、地震速度的趋势面分析、速度滤波处理、井点校正及三维速度重建等处理,使得该区速度资料更进一步的靠近了真实情况,从而也对落实油田周缘其它构造打下了基础。
The velocity of 3D seismic data in Yanmuxi region exhibits drastically vertical and horizontal variation, high systematic error and local spectral point abnormal, which make it difficult to explore the low amplitude structures. The velocity data is much close to the actual situation through given wellsite velocity match, trend surface analysis of seismic velocity, pie slice, wellsite correction and 3D velocity reconstruction, which is helpful to ascertain other structures in the circumferential region of this oil field.
