Numerical Research on Force of PIG in Oil Pipeline

Pigging technique plays a very important role in managing pipeline running. On the basis of analyzing the pigging physical model, it was established of computation model of characteristic parameters for slug flow, the dynamic mathematical model and the relative numerical calculation method. A numerical simulation was realized. The results show that numerical simulation method can compute pipeline pressure distribution in the process of pigging, which can trace running situation of PID ball in the pipelines.
