摘要
介绍分层注水井流动测试技术 ,测试进入每一个层段的注水量、压力、温度等参数 ,能真实的反映出各个层段的吸水状况 ;同时 ,在测试过程中验证注水层段封隔器的密封性 ,不会造成地层污染。利用层面流褶积理论分析注水井的层段压力、流量资料 ,得到层段渗透率、表皮系数、吸水指数等资料。现场测试结果表明 ,该技术是掌握注水现状。
The paper introduces the flow testing technology for seperate zone waterflooding injection well,it can test water injection rate volume,individual-layer pressure and temperature of every layer,mirrorreally the status of hygroscope and check the sealing property of flooding packer.By using sandface rate convolution theory analyses interval pressure and flow data of water injection well,it can obtain individual-layer permeabilities,skin factors,water injectivity index for layered reservoirs.Through on-site testing,this technology is an effective monitoring method for handling current situation of water injection and adjusting water injection structure.
