【摘要】 近年来,对北大港构造局部地区进行了三维地震二次采集和处理,所获地震资料地层反射波组特征清楚、信噪比高、分辨率高,为开展地震储集层预测打下了基础。概述了目前地震储集层预测技术基本状况,对地震切片技术、地震属性参数分析、储集层地震反演技术、分频解释技术基本原理及应用范围进行了分析,对港东地区新近系明化镇组河流相砂岩进行了预测,并对应用效果进行了讨论。更多还原

【Abstract】 In recent years, Dagang Oilfield Company conducted re-pickup and processing of 3D seismic data in local areas of northern Dagang oilfield and gained seismic data with highly vivid reflected wave groups, high signal-to-noise ratio and high resolution, which potently support the further seismic prediction of reservoirs in this area. This paper reviews the status of the seismic prediction technologies of reservoirs, including the principles and application scales of technologies such as seismic slice, seismic attribute parameter analysis, reservoir seismic backward modeling and frequency-shared interpretation. By using this technology, the fluvial sand of Minhuazhen formation of Neocene in Gangdong area is predicted, and the applied results are discussed.更多还原
