摘要
结合矿场实验,提出一种间歇式注CO2技术。该技术可提高CO2波及系数,减少CO2在储层中的反应时间,主要适用于CO2气体采油技术。注CO2控水吞吐采油在高含水稠油油藏开发效果已通过生产实践验证。
Combined with field experiments,this paper proposes a novel injection mode-intermittent CO2 injection technology.This mode raises CO2 sweep efficiency,decreases reaction time of CO2 within reservoir,and improves production efficiency while reducing the cost.The mode is suitable to CO2 production technology.Water-control CO2 huff-puff is effective to exploit high water-level heavy oil reservoir.
