【摘要】

：

当前航天器组成复杂、所处空间环境恶劣以及不可在轨维修,决定了航天器具有极高风险,而对航天器的健康状态进行监测,提供实时状态数据,可以快速定位航天器故障,给在轨抢救提供最佳时机.由于光纤光栅传感系统具有分布测量的特点,可对航天器的温度、振动、应变等进行实时测量,具有抗辐射、耐腐蚀、寿命长、不受电磁干扰等优点,非常适合于在轨应用.本文对航天器的故障特点进行了分析,提出一种基于光纤光栅的航天器在轨健康监

光纤监测技术在稠油热采中的应用

随着常规石油资源越来越少,国内外各大石油公司都加大了稠油热力开采的投入.国内的稠油油藏开发方式也正逐渐由蒸汽吞吐转向双水平井蒸汽辅助重力泄油.上述开采工艺的效果严重依赖于对井和油藏的动态监测能力,而能够满足上述动态监测需求的最佳手段就是光纤生产监测及解释.光纤监测及解释技术能够综合多种光纤传感器的测量结果,长期实时监测稠油热采井下温度、压力及其变化情况,来分析和解释不同油层部位的动用情况,为稠油热
