| 摘 要： | 永安高精度三维地震工区地表复杂,勘探目的层为典型的复杂断块油气藏。针对该区地震资料的问题和特点,开展了大量细致的试验分析,总结形成了一套具有针对性的高精度三维地震资料处理技术。首次采用了层析成像静校正处理技术,消除近地表静校正量的影响,提高了地震资料的信噪比;针对多次波干扰和火成岩的影响,采用反Q滤波、拉冬变换及串联反褶积的处理技术消除了多次波、火成岩对有效反射的影响,改善了火成岩附近有效反射的成像效果;使用高精度三维叠前时间偏移,提高了分辨率和信噪比。

| Abstract: | In the high-precision 3-D seismic work area of Yong’an,the surface conditions are complicated,and the exploration target zones are typical complex reservoirs.According to the characteristics of high precision 3-D seismic data of the area,a set of specific 3D high-resolution seismic data processing process is formed by a large of analysis and experiments.The tomography static correction is used for the first time to remove the influence near the surface and improve the signal-to-noise ratio.The interference of multiple and igneous rock is removed by the technologies of inverse Q filter,Radon transform and series disconsolation to improve the effect of imaging.Imaging quality,resolution and signal-to-noise ratio are improved by high precision 3-D pre-stack time migration. |
