Research and development of a dynamic temperature and stress monitoring probe for hydrate reservoirs based on fiber optic sensing technology

摘要:
水合物生成与分解以及加载变形下含水合物沉积物内部的温度、应力变化规律对破解水合物储层失稳破坏的演化机制至关重要。为了监测含水合物沉积物内部温度、应力在水合物生成、分解、变形等全过程中的演化机制，本文提出一种基于光纤传感技术的含水合物沉积物温度、应力监测方案，并研制了集温度、应力监测于一体的光纤探头，实现了从沉积物装样到水合物合成到加载变形，再到水合物分解过程中试样温度和应力的监测。与常规热电阻温度传感器和加载压力传感器监测数据初步对比表明，二者具有一致的变化趋势。但在数值上存在一定差异，分析认为是储层的非均质性、应力加载端与光纤感测端的距离变化共同导致。整体而言，光纤感测探头可以较好地捕捉因水合物合成产生的挤压应力升高与水合物分解过程中含水合物沉积物水平应力的降低。
Abstract:Studying the changes in temperature and stress of hydrate-bearing sediment (HBS) during hydrate growth, decomposition, and deformation is crucial for understanding the destabilization mechanism of hydrate reservoir. To monitor the changes of internal temperature and stress in HBS during these processes, we proposed a temperature and stress monitoring scheme for HBS based on fiber-optic sensing technology, for which an optical fiber monitoring probe was designed. The feasibility and precision of the probe in the temperature and stress of HBS were compared with those of conventional sensors. Additionally, the changes of horizontal stress of HBS during hydrate formation and dissociation were effectively monitored by the optical fiber sensor. Experimental results show that the stress and temperature obtained by fiber-optic probe exhibit similar trends to those obtained with conventional sensors. However, some differences were observed due mainly to the heterogeneity of the HBS and the distance between the loading point and the sensing point. Overall, the fiber optic probe could better capture the increase in compressive stress caused by hydrate formation and the decrease in horizontal stress of hydrate-bearing sediments during hydrate decomposition.
