Process Calculation Method Study and Application of Oil-Gas Multiphase Transportation Pipeline

Pressure and temperature´s accurate calculation of the oil-gas multiphase transportation pipeline is the key of the process calculation study, and it has important significance to the production run of pipeline. According to the needs of the engineering application, and based on the data of actual pipeline, this paper amends the key parameters of the pressure drop and temperature drop models, and puts forward a correction calculation method of the pressure drop and temperature drop, so that it can meet the need of the practical application. Last this paper calculates and analyzes a long-distance oil-gas multiphase transportation pipeline, and gets reasonable results, so it provides strong support to the production run of pipeline.
