注水开发油田稳产界限研究

PRODUCTION STABILIZATION LIMITS OF WATERFLOODING OIL FIELDS

本文依据喇、萨、杏油田开发资料，通过数值模拟计算，并结合国内外油田的开发资料分析，阐述了注水开发油田稳产期末可采储量采出程度与采油速度关系，论证了油田稳产期末剩余可采储量采油速度界限，并测算了不同开发区块的稳产期。

Based on developing data of La,Sa,Xing oil reservoirs,through numerical sim- ulation calculation,and in combination with analysis of developing data of oil fields both at home and abroad,this paper expounds the relationship between production rate of recover-able reserves and recovery rate at the end of production stabilization period of waterflooding oil fields,verifies the limits of recovery rate of recoverable reserves.and predicts the productioii stabilization period of different developing areas.
