| 摘 要： | 蒸汽喷射泵是以水蒸汽代替普通喷射泵的动力液为原油举升提供能量，并可用来提高井筒内原油的温度。根据热力学原理和井筒举升理论，研究了井底流压和喷射泵喷嘴组合变化时井筒压力、温度和干度的变化规律。研究结果表明，在注入蒸汽干度一定的情况下，油井产液量越高，所需蒸汽量越大；在油井产量相同的情况下，井底流压越高，所需蒸汽量越少；利用同心管注蒸汽比用平行管注蒸汽所需的蒸汽量少。

| Abstract: | Steam jet pump is a kind of oil production device which can supply energy for oil lifting and improve the temperature of oil in wellbore. Instead of liquid used in general jet pump, steam is taken as motive power medium for steam jet pump. Based on basic principles of hydromechanics and thermodynamics, regularity of the steam flows in the pump was studied. The relations among injection pressure, temperature and steam quality under the conditions of different at flowing pressure bottom hole and spray nozzles of pump were analyzed. Under a certain steam quality, steam injection rate increases with liquid production, and it decreases with increase of flowing pressure at bottomhole under the same liquid production. The steam injection rate by using concentric tubing string installation is less than that of parallel tubing string installation. |
