摘　　要：目前重震联合反演主要采用二度或二度半模型,由于油气勘探中的地质构造一般为三度模型,因此,研究三度体模型的重震交互反演方法十分必要。根据南方海相油气勘探的实际情况,实现了基于三度体模型的可视化重震交互反演,并以理论模型说明了三度体模型的必要性。将该方法应用在我国南方海相某油气勘探区,较好地解决了海相地区地震资料品质差、信噪比低导致地震解释模糊甚至无法解释的难题,取得了较好的地质解释效果。Joint gravity and seismic inversion mainly adopts 2-D or 2.5-D models. As geological structures in oil & gas exploration are three dimensional, it is necessary for us to study methods suitable for 3-D models. We realized joint gravity and seismic inversion on 3-D models constructed according to the actual structures, and applied it to the real data from a working area in southern China. The method overcomes the difficulties of poor seismic data quality and low signal-to-noise ratio in marine facies areas.
