摘要
20世纪80年代以来,非地震地球物理勘探仪器有了长足的进步,采集精度的提高,采集手段与参数的多样化,为我国西部新区和南方海相碳酸盐岩地区的油气勘探提供了新的方法和途径,同时对数据处理与解释也提出了更高的要求。山区重力资料曲化平,小波分析及高阶统计量等现代信号处理方法,重震、重磁、电震的联合反演与交互反演,三维可视化反演,BP人工神经网络方法等在综合地球物理处理解释中得到广泛应用。在我国西部新区与南方海相碳酸盐岩地区,综合地球物理数据处理新方法技术的应用取得了较好的地质效果。
Since 1980s, non-seismic geophysical instrumentation has achieved great progress in its acquisition accuracy, gathering styles and diversification of parameters, which provides new approaches for petroleum exploration in the newly developed area of Western China and Southern marine carbonate area, and also makes higher demands on data processing and interpretation. Many new methods, such as reduction of gravity data to a horizontal plane, wavelet analysis, higher order statistics, joint inversion and interactive inversion of gravity, magnetic, electric and seismic data, 3-D visualized inversion, as well as BP artificial network method have been widely used in the integrated data processing. The performances of the new methods were illustrated with real data from the newly developed area of Western China and Southern marine carbonate area.
