Abstract: In oil-gas gathering process of tree type double pipes mixing heat water, energy consuming of system is related to quantity and temperature of mixing water, diameter of pipes, output of wells, ratio of water in oil, viscosity of liquid transfered.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 model of parameters optimization is established with energy consuming and investment of system as an objective function, pressure of well head, temperature at booster, range of diameter of pipes that can be used as restrain conditions.The model is non-linear and can be solved with direct array square method.Chart of calculating process for computer is given.Energy consuming can be decreased while engineering design is made with the software having been worked out, and rate, quality of design can be increased.

Key words: oil-gas gathering, system, parameter, optimization technology, study
