摘　　要：基于分布式光纤测温技术研制了一套天然气水合物开采井筒温度监测实验平台,主要包括水合物储层模拟室、温度控制模块、井筒结构模块、信号采集模块。结果表明,分布式光纤测温系统在低温环境下具有良好的适用性,该实验平台可有效获取水合物开采井筒的温度剖面,实现对井筒环空液位的预测及水合物开采方案的优化。Methane hydrate( natural gas hydrate),a highly efficient clean energy reserve,is a potential alternative energy source. In order to carry out scientific experiment and teaching of wellbore and reservoir temperature monitoring in hydrate production,a hydrate production wellbore temperature monitoring experimental platform is developed based on distributed optical fiber temperature measurement technology. The platform mainly includes hydrate reservoir simulation room,temperature control module,wellbore structure module and signal acquisition module. The result shows that the distributed optical fiber temperature measurement system has good applicability in low temperature. The experimental platform can effectively obtain the temperature profile of the hydrate production wellbore,predict the annulus liquid level and optimize the production scheme. The experimental platform is also used to carry out experimental teaching to realize the combination of theory and experimental teaching.
