摘要： 针对长庆油田川平4 6 - 2 3集输管路, 利用管路的现场参数, 通过对比分析优选出合适的流型划分模 型、 持液率模型、 压降模型以及蜡沉积模型。对上述模型编程求解, 分析了集输管路运行压力、 温度、 持液率、 有效内 径、 气/液相表观流速、 蜡沉积速率等随管道长度与运行时间的变化规律。模拟结果表明, 在运行3 6h内, 随管道长 度的增加( 除前6 0m) , 结蜡速率减小, 压力降低, 温度降低, 气相表观流速增大, 液相表观流速减小, 持液率减小; 随 着运行时间的增加, 同一节点处的蜡沉积速率增大, 压力降低, 温度升高, 气、 液相表观流速增大, 持液率减小。

Abstract: It is difficult to manage gathering & transportation pipelines because of their complicate operating conditions. Based on the Chuanping 4623 gathering & transportation pipeline in Changqing oilfield and its operating parameters. The appropriate models, such as flow pattern model, liquid holdup calculation model, pressure drop calculation model and wax deposition model, were selected by comparative analysis. Then, the variation of operating pressure, temperature, liquid holdup, effective inner diameter, gas/liquid superficial velocity and wax deposition rate with pipe distance and operating time was analyzed by programming and calculating the models. The simulating results showed that the wax deposition rate, pressure, temperature, liquid superficial velocity and liquid holdup reduced, while gas superficial velocity increased with the increasing of pipeline length (except for the first 60 meters). The wax deposition rate, temperature, gas/liquid superficial velocity increases, the pressure and liquid holdup decreased at the same node with the increase of operating time within 36 operating hours.
