摘要
光纤中分子的热振动与光子相互作用发生能量交换的对应关系是分布式光纤温度测试(FODTS)系统的工作原理,以辽河油田一个稠油水平井井组为例,简述了分布式光纤温度测试方案设计,分析了分布式光纤温度测试剖面,提出了井间热连通分为热液体连通和汽窜两个阶段,认为该稠油水平井井组本轮注汽后36.7%水平段达到热液体连通,并未进入汽窜阶段;油层物性在井间热液体连通前对热量传递影响较大;井间热连通评价结果与测井解释成果相结合分析可以客观、全面掌握油藏受热动态。
The rule of energy exchange correspondence of molecular thermal vibrations of fiber-optic and photon interaction is principle of fiber-optic distributed temperature sensing operation. The examples of the fiber-optic distributed temperature system (FODTS)applications of a heavy oil horizontal well group in Liaohe Oilfield outlines the basics and installation of the system, and the results of system test temperature profile is analyzed. The hot inter-well communication is divided into two phases, i.e. thermal fluid connectivity and steam breakthrough. Results show that the efficiency of thermal fluid connectivity has reached 36.7% of horizontal length after this round injection and hot inter-well communication hasn′t accessed steam breakthrough phase. The reservoir properties have a big influence on heat transfer before thermal fluid connectivity phase. The integrated interpretation of hot inter-well communication and well log is used for heated reservoir performance completely and objectively.
