萨中开发区高含水后期水驱开发含水及产量趋势分析

Trend analysis of water cut and production in high water cut in late period of water drive development in Sazhong block

根据水驱开发调整阶段含水率与采出程度变化关系曲线三段式的特点 ,给出了S +ΔER 含水率预测分析方法 .利用该方法预测了萨中开发区“十五”期间的含水变化趋势 .进入“十五” ,萨中开发区含水上升率将是一个从低到高再到低的变化过程 .用S +ΔER 含水率预测法及定液求产法预测了萨中开发区在“控水提液”及“全面提液”情况下含水上升率及产量递减率的变化趋势 ,确认“控水提液”开发效果好于“

According to 'three sections' characteristic of the change curve of percentage of water and recovery percentage in water drive development adjustment period, this paper gives the method of prediction and analysis percentage of water. We use the method to predict change trend of the water cut in Sazhong block in the 10th five\|year plan period. The compositive water cut in Sazhong block's change process will be from low to high and to low. We use the method of ' S +Δ E R ' ( prediction method of water percentage ) and the method of fixed rate of liquid to seek for the rate of production to predict the change trend of the rate of increase of water cut and the declining rate of oil recovery on condition that we control rate of water and increase the rate of liquid at the same time or increase the rate of liquid comprehensively, we think the former's development effect is better than the latter.
