分布温度是通过DTS系统激光器发送一束激光到光纤中进行测量的。这种温度测量可以连续进行而不影响油井开采和产量 ;光纤安装有单头和双头两种方式 ,双头安装具有很高的精确度和分辨率 ,特别适用于需要分析温度变化很小的油井。现场应用表明 ,光纤DTS系统在油田开发中可连续监测油井性能 ,是操作者优化油井注水和采油作业工艺的可靠方法。
The distribution temperature is measured by the DTS system laser sending a laser beam into the fiber. This temperature measurement can be carried out continuously without affecting the production and production of oil well. The optical fiber is installed with single head and double head. The double head mounting has high accuracy and resolution. It is especially suitable for analysis of small temperature changes Well. The field application shows that optical fiber DTS system can continuously monitor the performance of oil well in oilfield development and is a reliable method for operators to optimize the process of water injection and recovery of oil well.
