摘要
河流储层建筑结构识别与预测已经成为高含水后期油田提高采收率的基础地质保障。根据河流储层层次性,采用层次建模方法,分别对高弯度曲流河储层和辫状河储层进行层次识别和预测;在高弯度曲流河内,逐层次建立起高弯度曲流河河道、河道内部点坝以及点坝内部侧积层分布;在辫状河储层内,逐层次建立辫状河道、心滩、落淤层等分布,形成高精度的三维储层建筑结构模型。新井检验表明模型具有较高的精度,数值模拟则揭示了夹层对剩余油分布控制作用,表明层次建模方法建立的储层建筑结构模型能够指导油田生产和剩余油挖潜。
The recognition and forecasting of the fluvial architecture object is a key task on enhancing oil recovery in the late development stage of oilfield. According to the hierarchy of the fluvial object, the hierarchical modeling method is used to predict the architectural element in high sinuous river and braided river. In high sinuous river, the channel, point bar and HIS is modeled in order, and the same thing is executed in braided river. The new drilling wells show that the model has comparable precise and the numerical reservoir simulation shows the remaining oil is constrained by the deformed bedding, which is proved by the production data. The results show that the model constructed by the hierarchical modeling method can be used to conduct the production and enhancing oil recovery.
