摘　　要：为解决海上油田勘探开发面临的难题,地震采集开始向宽方位方向发展。较传统窄方位采集相比,宽方位采集能够更好地反映地下介质的各向异性特征,从而改善地下地质目标的成像精度。文章介绍了海上宽方位地震采集方式、观测系统参数设计方案以及宽方位处理技术,并针对目标工区开展了宽方位采集实践,应用效果显示宽方位地震资料采集能够较好地提升火山机构成像质量。In order to solve the difficulties faced by offshore oil field exploration and development,seismic acquisition has begun to develop in a wide direction.Compared with traditional narrow azimuth acquisition,wide azimuth acquisition can better reflect the anisotropic characteristics of underground media,thereby improving the imaging accuracy of underground geological targets.This paper introduces the offshore wide azimuth seismic acquisition method,observation system parameter design scheme,and wide azimuth processing technology.The target work area has carried out wide azimuth acquisition practice,and the application effect shows that wide azimuth seismic data acquisition can effectively improve the imaging quality of volcanic institutions.
