过环空集流产出剖面测井在塔里木油田的应用

THE APPLICATION OF THROUGH-ANNULUS FLOW-CONCENTRATING PRODUCTION PROFILE LOGGING IN TARIM OILFIELD

随着油田开发时间的推移,综合含水率逐年升高,产油量逐渐降低,地层能量越来越低,抽油机大量投入使用。过环空集流产出剖面测井启动排量低,适合低产量井的测井,能正确反映生产井各射孔井段的产出状况,为油田开发提供了第一手动态监测资料,最终实现油田稳油控水的目标。本文简单介绍了集流产出测井仪的原理,解释图版的研制以及如何使用图版进行产出剖面解释,最后运用实例说明了过环空集流产出剖面的解释流程以及应用。

With development of the oilfield,general water-cut rises year by year,oil production declines gradually,the formation energy becomes lower and lower,and pumping units are widely used in the oilfield.Through-annulus flow-concentrating production profile logging,which starting displacement is low and suitable for low yield wells,correctly reflects the production status of each perforated interval in a production well.It can provide first hand dynamic monitoring data for oilfield development to finally achieve the goal of stable oil production and water control.This paper simply introduces the principle of the tool,development of the interpretation chart and how to use it.It also gives some examples to show the interpretation procedures and application.
