摘　　要：针对实际需求,改进了传统的多步中值滤波方法,提出了一种多窗口最小峰态约束的多步中值滤波技术,在有效压制随机噪声的同时拥有优秀的边缘保持能力。在渤海油田渤中某区块运用该技术进行资料处理,大幅提高了资料质量,处理后的敏感地震属性可以进行准确的不连续界线刻画及拾取,有利于识别储层内的隐蔽信息,为油藏勘探和井位部署工作提供至关重要的保障。In this paper,according to the actual needs,we improve the traditional multi-step median filtering method,and propose a multi-step median filtering technology with multi window and minimum kurtosis constraint,which can effectively suppress random noise and have excellent edge preserving ability.Using this technology to process data in Bozhong block of Bohai oilfield can greatly improve the quality of data.The processed sensitive seismic attributes can accurately depict and pick up the discontinuous boundary,which is conducive to identifying the hidden information in the reservoir and providing the vital guarantee for the reservoir exploration and well location deployment.
