摘　　要：光纤传感器测温在国外油气田开发中的应用越来越广泛,它可以测出井下的实时温度曲线,且可以实现全井段测量。而水平井实时温度曲线一定程度上反映进入井筒流体的类型和流量。本文介绍了光纤测温技术特点及其现场应用状况,描述了温度曲线在判别水平段进气、进水点中的应用。Use of optic fiber distributed temperature sensors is becoming increasingly common for producing sections of horizontal wells through a real-time measurement of a temperature profile. This information can potentially be inverted to infer the types and amounts of fluid entering along the wellbore. In this paper, the unique features and applications of optic fiber distributed temperature sensing technology are summarized, and the way of temperature profiles inverted to infer the types of fluid entering along the wellbore is also described here.
