【摘要】：油田开发阶段,同期展示河、砂、泥的关系对于理清砂体的内部结构、点砂坝之间的关系及部署注采井位都非常重要。文中以渤海海域A油田B砂层为靶区,使用90°相移数据体,在多种刻画河道、砂体算法优选的基础上,实现河砂数据体融合,并展示河、砂、泥同期关系。通过与井资料结合研究证实,数据体反映的河、砂、泥关系等与井数据吻合。运用该方法,研究了河道发育演化、点砂坝内部结构,实现了从成因、过程视角来恢复和重建曲流河道历史演化过程,为剩余油的挖潜及高产调整井的部署提供了有力依据。
[Abstract]:In the stage of oilfield development, it is very important to show the relationship among river, sand and mud in the same time to clear the internal structure of sand body, the relationship between point sand dam and the location of injection-production well. This paper takes B sand layer of A oilfield in Bohai Sea as target area, uses 90 掳phase shift data body, realizes river sand body fusion on the basis of various channel description and sand body algorithm optimization, and shows the relationship among river, sand and mud. Combined with well data, it is proved that the relationship of river, sand and mud reflected by the data body is consistent with the well data. Using this method, the development and evolution of the channel and the internal structure of the point of sand dam are studied, and the historical evolution process of the meandering channel is restored and reconstructed from the perspective of origin and process, which provides a strong basis for tapping the potential of the remaining oil and the deployment of the high yield adjustment well.
