分布式光纤温度传感器（DTS）能连续实时监测水平井不同渗透率分布及气井产量生产时的井下动态。由于储层渗透率分布和产量对气藏水平井温度影响较大且变化无规律，致使目前基于DTS数据定量解释水平井产出剖面仍是一技术难题。文中基于水平井温度剖面动态模拟实验装置开展了室内模拟实验，在储层恒温情况下分析了不同渗透率分布和气井产量生产时水平井温度分布特征，定量评价各因素对水平井温度分布特征规律，为实现基于DTS测试定量解释产出剖面和储层参数等奠定实验基础。

Distributed optical fiber temperature sensor (DTS) can real-time monitor the downhole performance of horizontal wells with different permeability distribution and gas well production. As the permeability distribution and production have great influence on the temperature of horizontal wells and change irregularly, it is still a major technical problem to quantitatively interpret the production profile of horizontal wells based on DTS data. The temperature dynamic indoor simulation experiment is carried out based on the dynamic stimulation experimental device of horizontal well temperature profile, which analyses the temperature distribution characteristics of horizontal wells with different permeability distribution and gas well production to quantitatively evaluate temperature distribution low. Furthermore, it lays the experimental foundation for quantitative interpretation of production profile and reservoir parameters based on DTS test.
