摘要
风城油田重32井区齐古组超稠油油藏小井距蒸汽驱先导试验,生产后期暴露出汽窜干扰严重、注汽参数不合理,制约了蒸汽驱试验开发效果。应用数值模拟技术对试验区蒸汽驱方式、注汽参数和井网调整进行了模拟优化研究,研究结果表明:在剩余油富集区,采取注汽速度70t/d,井底蒸汽干度大于50%,注60天停30天的间歇汽驱方式可提高开发效果。
The super heavy oil reservoir of Zhong 32 Well block Qigu formation in Fengcheng oil field carried the Small well spacing Steam flooding pilot tests. The production practice shows that due to Steam channeling interference,the steam overlaying and steam injection parameters are not reasonable in post production,leading to reservoir producing uneven,production fluctuation,poor development effect. Using numerical simulation technology,aiming at the exposed problem as serious steam channeling interferen or unreasonable steam injection parameters in the steam flooding late test,carring out the numerical simulation research. The research shows that taking Steam injection rate 70 t / d,bottom hole steam quality above 50% and Intermittent steam injection for 60 days and to stop 30 days of flooding can improve the development effect.
