Abstract: According to oil-gas gathering process of single or double ring-type pipelinemixing with heat water,a method of calculating hydraulic and thermodynamic parameters such as flow,ratio of water in oil,pressure,temperature,specific heat for oil,gas,water pipe net is presented.A parameter optimization model for multiobjective is established with heat and electricity consumption,system investment as an objective function,and with pressure,temperature,range of diameter of pipes as restrain conditions.A method of solving the problem is given also.The authors pointed out that the higher investment and electricity consumption are resulted from the longer section with mixing heat water in the process of double ring-type pipeline.Mixing water is more concentrated in the ring part of the single ring-type pipeline process,so the heat consumption is larger in this process.Based on the objective function in this paper,the process of double ring-type pipeline for mixing heat water ought to be used.
