大港滩海地区地震沉积学研究
|
摘要
在井点少、井网不规则的滩海地区,基于井资料的研究方法对储集层研究精度低,难以满足油藏开发研究的需要。在大港埕海油田Ⅰ区开展地震沉积学研究,通过纵向与平面信息相互约束和标定,实现对辫状河心滩单砂层内部结构的细致刻画。对地震资料进行相位转换和地层切片处理,利用切片上的振幅特征对研究区心滩砂体平面分布进行解释,并通过不同深度的地层切片特征研究心滩演化过程。研究发现,研究区馆I1-1小层上部心滩单砂层可以划分为3次洪水期形成的心滩沉积。通过直井和水平井组的解剖研究,验证了地层切片揭示的沉积特征及演化规律,在此基础上建立了研究区沉积模式,对指导研究区水平井开发和无井区储集层沉积特征精细研究具有重要意义。
In shallow sea areas with irregular well pattern and sparse well control,the accuracy of reservoir characterization based on well logging data is too low to satisfy the need of reservoir development research.A seismic sedimentologic study is made in the Block I of Chenghai Oilfield,Dagang.The architecture of braided bars is characterized finely by the inter-calibration and inter-restriction of vertical and horizontal information.Seismic data is processed with technologies of phasing and stratal slicing and then the amplitude on slice is interpreted to obtain the planar distribution of bars.The evolution of braided bars is analyzed with research on slices of different depth.In this research,sand layer of the braided bar in NgI1-1 formation is subdivided into three parts,each of which is formed by a stage of flood deposition.The sedimentary characteristics and evolution revealed by stratal slice interpretation is verified by fine research of vertical and horizontal wells.A sedimentary model is built and will play an important role in horizontal well development and in the architecture characterization of reservoirs without wells.
