海区油气勘探重磁成果处理解释主要依靠有效的处理技术与综合解释技术来实现。文章介绍了剖面重磁地震综合解释、小波多尺度分解、全磁纬变倾角化极、三维正演拟合、地热岩石圈底界反演等项技术以及运用这些技术进行剖面、平面重磁成果处理解释的应用实例。重磁成果能有效地为油气勘探服务,也能为基础地质研究服务。海区油气勘探的捷径:多专业、多学科协同施工,成果结合,综合解释。

Good processing techniques and comprehensive interpretation are mainly used for gravity and magnetic data of offshore oil-gas exploration. In the text, a number of good techniques (comprehensive interpretation for gravity-magnetic and seismic data on profile, multiscale decomposition of wavelet, turning to the pole by all magnetic latitudes variable inclination, 3D forward simulation, geothermal lithosphere bottom inversion) and actual instances of processing and interpretation for gravity and magnetic data on profile and plane are recommended. Gravity and magnetic data are used in oil-gas exploration and studying basic geology. Combination of results and comprehensive interpretation is a short cut to offshore oil-gas exploration.
