【摘要】 辽河盆地由于其特殊的地震地质条件,以往采集的深层地震资料主频多在20～25Hz左右,以往的地震资料已变成辽河探区勘探工作的“瓶颈”,制约了油田的进一步勘探和开发。为了满足精细构造解释与油藏描述对地震资料的需求,辽河油田在大民屯地区开展了一系列的采集方法攻关,形成了一套完整的精细三维地震采集技术方法,在二次地震采集中取得了较好的应用效果。更多还原

【Abstract】 Due to the special condition of seism and geology in Liaohe Basin, the predominant frequency of seismic data collected in deep strata before concentrated around 20-25Hz.These old seismic data has become the"bottleneck"of exploration work in Liaohe area, which has restrained the further exploration and development of Liaohe Oilfield. To meet the fine structure interpretation and oil reservoirs description requiring for seismic data, Liaohe Oilfield tackled the key problem using a series of acquisition methods in Damintun area, formed a completed fined 3-D seismic acquisition technique, which is applied and made better effect in secondary collecting.更多还原
