Selection Principle Of Stopping Injecting The High Permeable Well And Performance Analysis

摘要

Stopping injecting the high permeable layer is a scheme of adjustment of polymer flooding development later,it is mainly for reducing the conflicts between layers,which makes the thin and poor reservoirs to can be used,improve the producing degree of profile,improve the development effect of polymer flooding.This paper through the section have been performed on selected principles of hypertonic solution well stop and stop hypertonic wells producing degree,pressure changes,peripheral production well water cut change as well to stop block B in A oilfield of hypertonic analysis.The results show that,the successful stop high permeability layer wells,profile producing degree increased,apparent water injectivity index drops,production well water cut down.
