随着高分辨率地震勘探技术的提高, 地震勘探的精度也越来越高。在大庆探区内, 地震资料处理在高保真的情况下, 中浅层资料的主频已达到50HZ以上, 视频在70Hz以上, 分辨率较常规二维地震资料提高一倍多。因此, 资料解释方法也不同于常规二维地震资料解释方法, 正向高、精、细的方向发展。高分辨地震资料解释方法在实际生产中取得了满意的应用效果。

With the progress of high resolution seismic prospecting technology, seismicprospecting precision becomes higher and higher. In Daqing prospect area, the dominant frequencyof shallow-and medium-depth layer seismic data reaches above 50 Hz, the apparant frequency isabove 70 Hz. and the resolution increases more than double that of conventional 2-D seismic dataunder the high-fidelity seismic processing circumstance. Therefore, seismic data interpretationmethods are different from those of conventional 2-D data. High resolution seismic interpretationmethods have brought satisfactory application effects in practice.
