摘要
二氧化碳驱试井测试资料表现复杂渗流特性.解释分析某注二氧化碳试验区同井不同时间段和同时间段不同井的试井测试资料,应用复合区试井模型,得到表皮因数、流度和外推地层压力等油藏参数;比较二氧化碳驱前后地层流度和外推地层压力的变化特征,获得有效的二氧化碳驱开发参数;对试验区试井测试资料综合分析,反映二氧化碳驱受效情况.结果表明:与生产动态相吻合,准确反映油井生产状况.
Enhancing oil recovery considerably by CO2 flooding has become a more and more important method around the world.Due to the complex flow properties of well testing data through CO2 flooding,analyzing different well information comprehensively,which is contained in well testing data,is playing an important role.By comparing the data of same well in different periods and different wells in the same period,especially keeping eyes on the reservoir fluidity and pressure variations in CO2 flooding,we could obtain valid the CO2 flooding exploitation parameters,evaluate correctly the production process and provide reliable data for further research of production performance.In the meantime,CO2 flooding has taken effect in some wells and presents in accordance with production performance by overall research in CO2 flooding pilot.
