摘　　要：依托于山东省黄渤海海域高精度重力测量案例,系统性总结了高精度海底重力测量技术方法,并以牟平-即墨断裂、桃村断裂、海阳断裂、武宁断裂等陆域区域重大断裂为例,利用欧拉反褶积以及位场转换等数据处理方法,精确定位了断裂构造在海域的延伸展布位置,形成了高精度海底重力测量在探测隐伏断裂中的应用示范。结果表明:高精度海底重力测量方法可以有效提升浅海地球物理探测技术能力,为海洋基础地质研究、矿产资源勘查、重大工程建设等相关领域提供基础资料。Based on the case of high precision gravity measurement in the Yellow and Bohai Sea areas of Shandong Province,this paper systematically summarizes the high-precision seabed gravity measurement technology and methods.Taking major faults in land areas such as the Mouping-Jimo Fault,Taocun Fault,Haiyang Fault,and Wuning Fault as examples,using Euler deconvolution and potential field conversion data processing methods,the extension and distribution position of fault structures in the sea area was accurately located.The application demonstration of high precision seabed gravity measurement in detecting hidden faults has been formed.The results indicate that high precision seabed gravity measurement methods can effectively enhance the capabilities of shallow sea geophysical exploration technology,providing basic data for related fields such as marine basic geological research,mineral resource exploration,and major engineering construction.
