摘要
为实现老油田地面掺水工艺的简化优化,在水力和热力计算的基础上,利用Pipesim软件实现了双管掺水工艺、首端环状掺水工艺和末端环状掺水工艺的建模,研究了不同掺水方式、掺水量及掺水温度对能耗和运行费用的影响,并以总运行费用最低为目标函数,对不同工况下的最佳运行参数进行了求解。研究结果表明:随着掺水温度的升高,掺水系统的耗电量有所下降,随着掺水比的增加,耗电量呈先增加后降低再增加的趋势;耗气量与掺水温度和掺水比均呈正相关,在掺水比1.4之后的耗气量增幅不大;双管掺水工艺的运行费用最高,末端环状掺水工艺的运行费用最低。通过最优化求解,获得了不同月份的最优掺水温度和掺水量,工艺简化后,运行费用降低了63.3%~68.8%,年运行费用降低了37.31万元,节能潜力巨大。研究结果可为同类老油田地面方案的实施提供实际参考。
In order to simplify and optimize the surface water blending process of old oilfields,the Pipesim software was used to realize the modeling of double-pipe water blending,head-end ring water blending and end-end ring water blending based on the hydraulic and thermodynamic calculations.The influences of different water blending methods,water blending amount and water blending temperature on the energy consumption and operating cost are studied,and the lowest total operating cost is taken as the objective function.The optimum operating parameters under different working conditions have been seeking a solution.The results show that with the increase of water blending temperature,the power consumption of water blending system decreases,and with the increase of water mixing ratio,the power consumption increases first,then decreases and then increases.There is a positive correlation between air consumption and water blending temperature and water blending ratio,and the increase of air consumption will be small after water blending ratio is 1.4.The operating cost of doublepipe watering blending process is the highest,and the operating cost of end-ring watering blending process is the lowest.Through the optimization solution,the optimal blending temperature and water amount of different months are obtained.After the process is simplified to the terminal ring blending process,the operating cost is reduced by 63.3%~68.8%,and the annual operating cost is reduced by 373100 yuan,which has great potential for energy conservation.The research results can be provided practical reference for the implementation of similar old oilfield surface schemes.
