摘　　要：河南稀油田高含水开发后期,开发挖潜的重点已由主力层向非主力层转变,同时油井压力测试技术已不能满足现阶段油田开发和动态分析的需要。为此自主研发了油井分层测压工艺技术。该技术由封隔器、测压工作筒等工具组成,井下下入丢手分层测压管柱,利用环空测试的方法,从偏心井口下入测压堵塞器和压力计,封堵目的层,测取油井分层压力恢复曲线,利用测得油井的各分层压力,了解各层的出液状况,为油田后期的调整挖潜提供依据。At the later stage of the thin oil development in Henan oilfield,the focus of developing and tapping the latent power turns from the major reservoir to minor ones,and according- ly the regular techniques of pressure measurement fail to meet the requirements of oil field development and dynamic analysis.For this reason,a stratified pressure measurement for producing wells is studied and obtained independently. The technique consists of packer,working barrel of pressure measurement and other tools.In the technique,the dropping pipe strings for stratified pressure measurement is put into wells in the borehole;the blanking plug and manometer are laid down from the decentralized wellhead by using the annu- lus test method to seal off the subject reservoir and to meas- ure the stratified pressure recovery curve of pay off.Finally, the discharge situations of all strata are obtained through the analysis on all the measured stratified pressures of pay off, which provide the basis of later adjustment of development.
