| 摘 要： | 当地下地质构造复杂、断裂发育,横向速度变化不是太剧烈的情况下,提高偏移成像精度,三维叠前时间偏移是一种行之有效的方法。三维叠前时间偏移取得成功的关键:一是高保真、高信噪比的叠前数据;二是建立一个合理的三维偏移速度场。随着计算机性能的不断提高,三维叠前时间偏移逐渐成为常规处理技术,该技术在江苏油田WZD地区得到了广泛的应用,实际资料处理结果及钻探效果证实了三维叠前时间偏移技术是解决WZD地区复杂构造成像精度的一种好方法。 |

| Abstract: | While the geologic structure complexity,rupture growth and transverse velocity variety underground are not too exquisite,3-D prestack time migration is an effective method to improve migration imaging precision.There are two key factors for 3-D prestack time migration:one is the high fidelity high SNR prestack data;the other is to build up a reasonable 3-D velocity field for migration.With the advanced computer capability,3-D prestack time migration gradually becomes a general seismic data processing technology.In the WZD area in Jiangsu oil field,this technology has been applied widely.Practical seismic data processing and drilling results have proved that 3-D prestack time migration technology is a good method to resolve complicated structure imaging precision in the WZD area. |
| Keywords: | 3-D prestack time migration 3-D migration velocity model migration aperture signal-to-noise ratio anti-alias gap |
