井下的温度及压力参数是优化开发方案、提高采收率的依据.由于热采井井下具有高温高压、电磁干扰性强、化学腐蚀强、环境复杂恶劣等特点,传统的井下温度和压力测量方法存在不足.基于布里渊散射的分布式光纤传感测量系统不仅具有耐高温高压、灵敏度高、抗干扰性强的特点,而且该系统能够实现实时分布检测,可用于稠油蒸汽吞吐、气举采油、蒸汽驱、蒸汽辅助重力驱油(SAGD)等的温度、压力实时监测.%The numerical solution of the radial heat flow,the time factor were used for the exact solution algorithm for the establishment of heavy oil during steam injection wellbore temperature and pressure of the model and introduce polarization maintaining fiber distributed logging system works. This system can work in high temperature and pressure environment with high precision. It can be used in cyclic steam,gas lift steam drive,and steam assisted gravity drainage (SAGD) for temperature and pressure testing.
