摘要:
为预测大落差管道局部高点水击压力，避免在关阀、停泵等应急操作过程中因高点低压而使油品气化，采用OLGA软件水击计算模块分析介质流速、高点稳态压力、关阀时间、阀门位置对高点水击压力的影响机制，并结合国内某原油管道现场SCADA系统数据进行验证；采用通用全局优化算法（UGO）和列文伯格-马夸尔特法（LM）建立局部高点压力预测方程，相对误差在5%以内。研究结果表明：本文方程可实现大落差输油管道水击过程中局部高点水击压力的预测。研究结果可为大落差输油管道安全运行与管理提供参考。
Abstract:
In order to predict the water hammer pressure at local high points of pipeline with large drop and avoid the oil gasification due to low pressure at high points during the valve closing,pump stopping and other emergency operation processes,the water hammer calculation module of OLGA software was used to analyze the influence mechanism of medium flow velocity,high point steady-state pressure,valve closing time and valve position on the high point water hammer pressure,and the results were verified by comparing with the field SCADA system data of a domestic crude oil pipeline.The prediction equation of high point water hammer pressure was established by using the Universal Global Optimization (UCO) and the Levenberg Marquardt (LM) and the relative error was less than 5%.The results showed that the established equation can predict the water hammer pressure at high points during the water hammer process of oil pipelines with large drop.The research results can provide reference for the safe operation and management of pipe with large drop.
