Development of Technique Calculation Software for Gas-liquid Two-phase Flow Pipelines

The function of OGTPP includes that it is able to steady and transient calculating for wet natural gas, and it can use single model and component model to calculate technology parameter for oil-gas two-phase. At the same time the OGTPP has the compulsive module foe technology calculating and property parameter calculus. This software has good precision by means of compare with the measured data, and it can give the variable trend of pressure and temperature well. The example analysis shows that the OGTPP is easy to use and has good analysis ability, can satisfy the needs of multiphase flow pipeline designing and operating management.
