摘要:
针对研究区曲流河储层横向变化快，井少难以控制横向展布的问题，充分应用地震属性对曲流河河道的约束能力，在沉积模式指导下，应用井-震结合研究该区储层展布规律。通过井与平面地震属性结合研究河道的展布方向及规律，利用连井剖面与地震属性剖面结合认识河道边界，进而掌握了曲流河河道在平面展布和纵向上叠合规律，明确了该区主力储层的发育特征，有效解决了井少条件下难以控制储层横向变化的问题，研究成果有效支撑了该区的开发井部署。
Abstract:Meandering river deposits are changing strongly in lateral direction. It is difficult to define the lateral distribution pattern only with drilling data. Seismic attributes incorporated with drilling data are applied in this paper to delineate the spatial distribution of meandering rivers and the boundaries of the fluvial deposits under the guidance of the existing depositional model. Firstly, well data are used together with spatial seismic attributes to disclose the general extension of river channels. Inter-well cross sections and the seismic attribute profiles are then adopted to define the boundaries of channels. As the result, the distribution pattern of the meandering river channel deposits in a three dimensional framework is established. Practice proves that the result is effective to support the design of development wells in the area.
