【摘要】 针对稠油开采过程中采用人工化验法进行蒸汽干度测量时,随机性强且稳定性差的缺陷,采用V锥流量计结合流体体积变化法测量蒸汽干度,在线监测蒸汽干度及蒸汽压力等参数。通过分析蒸汽干度与蒸汽压力以及V锥流量计测得的压差之间的关系,证实蒸汽压力、流量和压差是影响蒸汽干度的主要因素,得出蒸汽干度与压差值成近似一次函数关系的结论。更多还原

【Abstract】 Aiming at the artificial steam quality measurement with strong randomicity and weak stability in thickened oil recovery,the method which combing V-cone flowmeter with fluid’s volume change was proposed to measure steam dryness and to monitor its pressure on line.Through analyzing the relationship between steam dryness and steam pressure and the pressure difference measured by the V-cone flowmeter shows that the steam pressure and flow rate and pressure difference mainly influence the steam dryness,and the relation between steam dryness and pressure approximates one-function relationship.更多还原
