摘要
定量化细分注水可确保注水井层位划分的更加精确,从而达到提高小层动用程度的目的.其技术界限一般是根据吸水剖面等动态数据和数值模拟方法划定的.结果表明:该方法可提高层位细分的精确性,很好的解决选井的复杂性和不均衡性,进而建立一套有效的低渗透油藏细分层位判别法.
Abstract
Quantitative layered water injection ensures a more precise delineation of the layers of the injection wells,which leads to an increase in the degree of mobilisation of the small layers.The typical way for defining technical boundaries is to use dynamic data,such as injection-proration and numerical modeling techniques.The results show that the method can improve the accuracy of layer subdivision,well solve the complexity and imbalance of well selection,and can establish a set of effective discriminative method of layer position in low-permeability reservoirs with split injection.
