Abstract:

TGNET software has been widely used in the world, it can not only simulate the single pipeline transportation simple model, but also simulate the complex technology system contain multi supply, multi loop network, multi compressors, and multi valves, et. It was a long history software for gas transmission pipeline simulation. In order to play a guiding role in the operation of nature gas transmission pipeline by TGNET software, the actual production of Shuang 6 gas storage with the TGNET software was simulated. The simulation process included: The establishment of the pipeline gathering and transportation network model; Determined the gas model, the gas state equation and the friction coefficient formula. Shuang 6 gas storage input the basic parameters of the supply, gas pipeline and delivery; Start the simulation and output results. According to the simulation results, making a comparison table of the simulated pressure values and the measured pressure values of Shuang 6 gas storage, a comparison chart of pressure was drawn. The consequences showed that the relative error was less than 4.3% between the TGNET software simulation results and the actual production pressure, obtained the result of TGNET software that was suitable for the actual production situation of Liaohe oil field Shuang 6 gas storage.

摘要： TGNET软件是一款历史悠久的输气管道模拟软件,可以模拟单管输送简单模型,也可以模拟多气
源、多循环管网、多压缩机、多阀门等在内的复杂技术系统,已经在全世界得到了广泛运用。为了使TGNET软件在
天然气输气管道运营中更好地发挥指导作用,利用TGNET软件对双6储气库实际生产情况进行了模拟。模拟过程
包括:建立集输管网模型;确定模拟时选用的气体模型、气体状态方程及摩阻系数公式,并输入气源、采气管线、集注
站基本参数;启动模拟并输出结果。根据模拟结果,对双6储气库模拟压力和实测压力进行了对比。对比结果表明,
TGNET软件的模拟结果与实际生产压力的相对误差小于4.3%,TGNET软件适用于辽河油田双6储气库的实际生
产情况。
