采用沙丘曲线法、交互折射静校正法以及分偏移距地表一致性剩余静校正等技术,较好地解决了静校正问题。
Static correction problem is resolved by adopted methods like sand dune curve, interactive refraction static correction, and offset-division surface-consistent residual static correction.
该技术是将动校正后的数据偏移到倾斜反射界面零偏移距位置上,能够解决深层构造成像问题。
The normai moveout corrected seismic data are mi-grated to the zero offset dipping reflector, which solves the problem in deep layer image.
采用部分近偏移距道叠加,避免出现远道动校正拉伸畸变;
The stacking of some near-offset traces avoids NMO correction stretching distortion on far traces;
由于动校正速度是随偏移距变化而变化的,而常规速度分析并没有考虑这一因素,动校正效果往往不是很理想,从而影响资料的叠加和成像效果。
The conventional velocity analysis does not consider the influence of the NMO velocity varying with offset, making the results not ideal, leading to a poor stacking and migration imaging.
由此,我们扩大了非双曲动校正方程的适用范围,从而实现了ATI介质中远偏移距非双曲时距的动校叠加。
Therefore, our work extends the application of the nonhyperbolic moveout equation to the ATI media and makes the nonhyperbolic moveout correction and stack of the far-offset in the ATI media.
