在以人工补充能量作主要驱动方式的二次采油中,以注水法最为普遍和重要,怎样注水才能更好的增产稳产,才能获得更髙的最终采收率和经济效益,成为多数油田主要开发阶段关键性的问题之一。本文不是研究这些问题本身,而是从“战术接替”角度讨论在注水开采过程中的注水方式、内部结构及所驱动的主要对象之间的接替,它们如何在不同阶段起主要作用等等。
In the secondary recovery of oil with artificial replenishment as the main driving method, the most common and important water injection method is how to inject water to achieve better yield and stable production, so as to obtain more ultimate recovery rate and economic benefits and become the major development of most oilfields One of the key issues of the stage. Instead of studying the issues themselves, the paper discusses the waterflooding, internal structure and succession of driven primary objects, how they play a major role at different stages, etc. from the perspective of tactical succession .
