摘要: 注汽锅炉是油田热采的主要动力设备、耗能设备之一。汽水分离器分离出的高温饱和水的热焓一般
通过换热器加以利用。但是,注汽锅炉水处理系统简单,而分离出来的饱和水中富含的钙、镁等离子易使管道表面
结垢,从而影响换热设备的换热效率。利用具有自洁能力的螺杆膨胀机回收饱和水余热,与未使用该设备的情况相
比,可提高注汽锅炉的热效率约10.2%,在服务期内可节省约4.56暳107 度电,折合标煤约18422.4t,效果显著。

Abstract: Steam injection boiler is one of the main power and energy consumption equipments in oil thermal production. Generally, the high temperature saturated water enthalpy which is separated by the steam separator is used through the heat exchanger. However the water treatment system of the steam injection boiler is so simple and the separated saturated water is rich in calcium,magnesium and other ions which are easy to foul pipe surface and affects the heat transfer efficiency of the heat exchange equipment. Comparing with the case of no using the equipment, the screw expander which is of a selfcleaning ability recycled the waste heat of the saturated water, which can improve the thermal efficiency by 10.2% and save about 4.56×107 kW·h amount to 18 422.4 t of standard coal in the service period. The effect is significant.

Key words: Steam injection boiler , Saturated water , Utilization of waste heat ,  Screw expansion machine
