摘要:
南海北部白云凹陷深水区勘探潜力大，但中浅层勘探层系单一，且中浅层圈闭所剩无几，为此深水勘探必须走向深层。该区早期地震资料以拖缆采集为主，采集所获得的地震资料方位较窄，制约潜山储层的预测研究。为此，此研究创新性采用ES360成像处理技术对窄方位拖缆地震资料进行处理，得到角度域全方位道集数据，该数据有效地弥补了窄方位拖缆地震资料的方位信息，能有效地开展叠前裂缝性储层表征；同时针对新的叠后地震数据开展多属性分析，与叠前裂缝储层进行多尺度表征融合，建立一套分尺度断裂体系描述技术。该技术应用于白云凹陷深水区L区潜山靶区，完成了海上拖缆窄方位地震数据的潜山储层预测，预测优质裂缝储层发育区，并且该技术也能应用于类似的潜山油气藏勘探开发中。
Abstract:
Abstrct：The deep-water area of the Baiyun Sag in the northern South China Sea exhibits significant exploration po tential. However，exploration in the shallow to middle strata has been limited by a relatively narrow target system and the depletion of available traps in these layers. Therefore，deep-water exploration in this region must extend in to deeper strata. Early seismic data in this area were primarily acquired using narrow-azimuth towed-streamer （NATS）acquisition geometry， which restrict buried-hill prediction due to limited azimuthal coverage. To address this limitation， this study innovatively employs ES360 imaging processing technology to reprocess the existing NATS seismic data. This processing generates angle-domain wide-azimuth（WAZ）gather data，effectively compen sating for the azimuthal information gap inherent in the original NATS data. Consequently， this enhanced dataset enables robust pre-stack fracture characterization of reservoirs. Furthermore，multi-attribute analysis was conduct ed on the newly derived post-stack seismic volume. These post-stack attributes were then integrated with the pre-stack fracture characterization results through a multi-scale fusion approach. This integration facilitated the devel opment of a hierarchical fracture system characterization technique. This integrated methodology was successfully applied to a targeted buried-hill prospect（Area L）within the deep-water Baiyun Sag，enabling effective prediction of buried-hill reservoir distribution and the identification of zones with high-quality fractured reservoir development based on the originally acquired offshore NATS seismic data. Moreover，the methodology is adaptable and can be extended to the exploration and development of similar buried-hill oil and gas reservoirs.
