Based on strong adaptability of wave equation finite difference depth migratio n to vertical and lateral changes of medium velocity, the paper presented a one way wave equation pre stack depth migration operator with optimal series. Ba sed on continuation calculation of finite difference wave field, it adds compe nsation correction aimed at operator errors, so that improves imaging precision of operator; meanwhile can basically eliminate dispersion of difference scheme a nd improve signal to noise ratio of imaging section. The operator is character ized by low order equation, imaging for steep dip and adapting for any changes in velocity field. Because all calculation in the paper is in frequency domain, the method has an advantages of high computational efficiency and imaging easily by comparison with finite difference algorithm in time domain. Impulse respons e test and results of pre stack depth migration for Marmousi model show that th e migration method is effective tool for “Three High” (high resolution, high s ignal-to-noise ratio and hi-fi) seismic data processing in strong lateral var ying velocity media.

基于波动方程有限差分法深度偏移对介质速度纵横向变化的强适应性,本文介绍了一种优化 系数的单程波方程叠前深度偏移算子。它在有限差分波场延拓计算的基础上,增加了针对算子误差的补偿校正,从而提高了算子的成像精度;同时也可以基本消除差分频散,提高成像 剖面信噪比。该算子具有方程阶数低且能对陡倾角成像的特点,能适应速度场的任意变化。 文中一切计算均在频率域进行,与时间域有限差分算法相比,具有计算效率高、成像方便的 优点。脉冲响应测试和对Marmousi模型进行的叠前深度偏移结果表明,该偏移方法是强横向 变速情况下“三高”(高分辨率、高信噪比和高保真)数据处理的有效手段。

The technology in computed radiography(CR) produces artefacts that are different from those found in conventional radiography.The imaging plate, the pl ate reader, image processing, laser printer and operator errors may all contribu te to the artefacts.If CR system users are aware of the probable cauaes of artef acts, it will be easier to efficiently eliminate them.

CR技术所产生的伪影与传统X线摄影所产生的伪影不同。成像板、读取装置、影像处理、激光相机以及操作者错误等均会产生伪影。如果CR的使用者能意识到产生这些伪影的可能性 ,则很容易地消除它们
