Abstract

Abstract

Based on the 2-fluid model and the theory of small perturbation, the pressure wave velocity model was put forward for the oil-gas mixing transportation in large span pipelines, and the computer program to solve this model was built. The conclusions based on a practical engineering example are as follow: in the process of multiphase mixing large span transportation, the change of pressure wave velocity is more influenced by the gas phase, even a small amount of mixed gas can affect the pressure wave velocity dramatically. With the increase of mixed gas, the pressure wave velocity decreases and the pressure response time extends. The pressure at the low point is higher than at the high point, so the gas compressibility factor at the low point is smaller than at the high point and the pressure wave velocity at the low point is bigger, meanwhile, the pressure response time at the low point is shorter. Moreover, at the low point of mixed transportation the mixed gas is compressed tremendously, so the pressure wave velocity there changes little and almost remains at a constant value; in contrast, the pressure wave velocity changes easily at the high point.
