技术介绍
稠油注蒸汽热力开采工艺技术是目前国内外主要的稠油开采手段,是用直流锅炉向井下注入饱和蒸汽加热油层降低稠油粘度达到开采目的。稠油注蒸汽热力开采工艺井下蒸汽干度监测至关重要,通过蒸汽干度监测可准确了解注汽井的蒸汽热损失,是掌握油层热含的关键技术。饱和蒸汽干度,就是单位质量湿蒸汽中所含干饱和蒸汽的质量,通常用干度来表示湿蒸汽状态,并通过它来确定其他状态参数。目前国内外还没有在线实测饱和蒸汽干度工艺技术。普遍采用的是通过测量井下的蒸汽温度、压力来计算干度,其误差很大,因为饱和蒸汽是汽液两相流,随着蒸汽环境、流动阻力、和热量的损失蒸汽干度是随时变化的,蒸汽干度是衡量蒸汽质量的重要依据,蒸汽干度的测量问题一直是国内外注蒸汽热力开采稠油的重要科技攻关课题。因此目前亟待提供一种稠油热力开采井下模拟实验装置,以模拟注汽井下实验和标定监测仪器的技术参数,为我国稠油热采技术的研发提供保证。
