Development of the Technological Calculation Simulator for Two-Phase Flow in Gas-Liquid Hybrid Pipeline

According to the basic rule of fluid mechanics and in combination with the latest domestic and foreign research results of two phase flow theoretically and experimentally, a new simulator TFTCS has been successfully developed, which covers the hydraulics calculation, thermodynamic calculation and flow regime prediction. The TFTCS can be used for technology calculations in the oil/associated gas or condensate gas transmission pipeline of offshore, desert and hilly zone. The software's structures, functions and ranges of application are presented in this paper, and simulative calculation is made on submarine wet gas pipeline of JZ 20-2 oilfield with TFTCS. The results are examined by comparing with producing data of JZ 20-2 oilfield or through a comparison calculation with the same kind software PIPHASE overseas. The example analysis shows that the TFTCS, being easy to use and having reliable calculation results, can satisfy the need of oil gas hybrid pipeline engineering design calculation and operation management.
