脉冲中子水流测井技术在注聚井注入剖面测试中的应用

Pulse Neutron Waterflow Logging Technology and Its Application in Injection Profile Testing in Injection Polymer Well

注聚井注入剖面测井受粘度等诸多因素影响,一直是近年来需要测井技术人员解决的一个测试难题。文章介绍了脉冲中子水流测井技术—测井仪器的工作原理、测试方法及其测试应用效果,说明该技术不仅可以准确测量注聚井注入剖面,而且可以在注聚井找窜、找漏、判断漏点位置等方面具有指导作用,有效解决了注聚井的测试难题,为油田开发提供了可靠的科学数据资料。

Injection profile logging in injection polymer well is affected by many factors such as viscosity,and this is always a testing problem that needs to be solved in recent years.This paper introduces chiefly pulse neutron waterflow logging technology-work principle of the instrument,testing method and application effect,and shows this technology not only accurately measure injection profile,but also has instruction functions in judging channeling,leakage and locating leakage position in injection polymer well.It resolves effectively testing problems in injection well,and provides reliable data information for oilfield production.
