摘要
随着稠油开采进入中后期,辽河油田脱水工艺主要存在加热能耗需求大、工艺系统抗干扰能力差、老化油产生量大处理困难、加热系统热效率低、成本高等诸多问题。针对上述问题,开展了稠油常温破乳脱水工艺、燃气相变加热炉替代燃煤锅炉、研发老化油处理工艺等技术改进。现场实施工艺改进后,油田加热能耗降低了65%;加热成本由5.09元/吨降至2.51元/吨;污水系统老化油日产生量由120 m3下降到60 m3,污水含油量由2 451 mg/L降至290 mg/L;脱水后老化油含水由50%降至3%~5%。
With the development of＇heavy oil recovery in middle and later stage, the dehydration process mainly exists problems such as high heating energy consumption demand, poor anti-disturbance ability of process system, large amount of aging oil treated difficultly, inefficient and high cost in heating system. Aiming at this problem, indoor test and field simulation technology research has carried out oil at ambient temperature demulsification and dehydration process, the phase-change gas-fired Furnace alternative coalfired boiler and the aging oil treatment process. The test results showed that heating energy consumption, the aging oil production in sewage system, the oil content in the waste water and the water content in the aging oil are aft reduced dramatically.
