摘　　要：传统的地震反演受到地震有效频带的限制,无法识别薄层信息。波形指示反演利用波形横向变化表征储层空间变异性,实现了一种新的高分辨率储层预测方法。该方法垂向上利用井的高分辨率,横向上利用地震的高分辨率,使反演的纵、横向精度同时提高。拓宽了反演确定性频带范围,使反演结果从完全随机走向逐步确定。在准噶尔盆地石南地区中,该方法成功预测了侏罗系薄储层,实现了油气滚动勘探开发的目标。Conventional seismic inversion is unable to identify thin formation for the sake of confinement of effective frequency band,nevertheless seismic motion inversion realized a new method of high resolution to predict reservoir bed by using waveform lateral variation in token of the diversity of reservoir space.It improves vertical resolution by using well log and horizontal resolution by using seismic data in inversion simultaneously.Not only widen the range of frequency band in certainty inversion,but also change the inverson result from full randomness into gradual definiteness.In SN prospect of Junggar basin,it forecast thin reservoir bed in Jurassic and achieve the destination of progressive exploration and development.
