摘要:
辽河油田生产原油以稠油为主，从油井通过管道输送至联合站。含水稠油在进入沉降罐的过程中，会因沉降罐的结构设置和油水混合液速度产生不同的速度场，导致温度场的波动，使脱出油含水率不能达标。采用 FLUENT 流场仿真软件，建立沉降罐温度场数值模型，将整个流场划分为配液管进液区域、沉降罐内部沉降区域及收油槽区域。分析进口温度分别为 60 ℃、70 ℃、80 ℃、85 ℃时，油水混合液在沉降罐中的沉降分离效果和配液管温度场的变化情况：沉降罐中的“水洗层”随着时间的延长而逐渐增厚；在计算时间内，沉降罐配液管出口以下部位，进液的同时未见明显的油层。沉降罐中温度低的区域，稠油粘度大，不利于油水分离。
Abstract:

Liaohe Oilfield mainly produces heavy oil. The oil is pipelined from oil well to complex station for dehydration processing. However，the sediment tank structure and oil/water velocity field are different，which result in the fluctuation of temperature field to bring out a lower dehydration rate. By adopting FLUENT software and establishing the temperature field model of the sediment tank，the velocity field is divided into the liquid inlet zone，sediment zone and oil gathering zone to analyze the settlement/separation effectiveness and temperature field differences at inlet temperature of 60 ℃、70 ℃、80 ℃、85 ℃. The numerical study shows that the water layer depth in sediment tank increases with time; below the inlet pipeline of sediment tank there is no obvious oil layer in calculation time. At the low temperature zone of sediment tank，the heavy oil is highly viscous and hard for dehydration.
