摘　　要：桂西地区油气资源成矿地质条件优越,是广西重要的油气资源成藏有利地区。本研究利用桂西崇左地区的区域重磁数据处理、结合油气地质等其他地质成果资料,对研究区内的盆地构造和隐伏岩体进行了定性—半定量分析,对断裂构造进行了有效厘定,深入研究了研究区地球物理场特征与油气地质构造的密切关系,查明了与油气相关的地质结构与构造,重点探讨了宁明、上思和海渊等3个盆地的油气资源前景,为桂西地区油气资源勘探起到重要的示范作用,也为今后广西其他地区的油气资源地质调查工作提供了参考范例。For the superior oil and gas geological mineralization condition,West Guangxi is an important fa-vorable area for oil and gas resources.Based on the regional gravity and magnetic data processing result in Chongzuo area,West Guangxi,combined with other geological achievement data such as oil and gas geology,this paper makes a qualitative and semi-quantitative analysis on the basin structure and concealed rock mass in the study area,the fault structure is effectively determined,and the close relationship between the charac-teristics of geophysical field and oil and gas metallogenic structure has been deeply studied in the research ar-ea.The geological structure related to oil and gas resources is identified,and the oil and gas resource pros-pect areas of Ningming,Shangsi and Haiyuan basins are discussed.The study result not only plays an im-portant demonstration role for oil and gas resource exploration in West Guangxi,but also provides a refer-ence example for the geological survey of oil and gas resources in other areas of Guangxi in the future.
