Study on Reducing the Thermal Conductivity of the Vacuum Insulated Tubing in Hydrogen Permeation Environment

open access: yes, 2015
摘要 世界上原油储量中稠油、特稠油和沥青油砂的比例极高,达到总储量的70%以上。然而,由于稠油粘度极高,常温下往往凝结成固态,开采和炼制的成本和技术难度都很高,因而,目前国际上普遍没有大规模开采稠油油藏,特别是开采成本和难度最大的海上稠油油藏。我国由于原油资源不丰富,出于能源安全的考虑而大量开采稠油,包括海上稠油油藏,因此,在海上稠油开采方面国际上可供借鉴的开采经验几乎为空白,只有一些陆上稠油开采经验供参考。 由于稠油的黏度随温度上升而迅速下降,因此目前世界各国的稠油主要都是采用注蒸汽加热的方式进行开采,
