Application of distributed parallel algorithm for long term crude oil scheduling

A graphic I/O crude oil scheduling system(GIOCOSS) was developed in this paper for solving the disadvantages in the present methods, such as poorness in solving long-term scheduling problem, complexity in modeling, difficult in model amendment and maintenance, etc.

The flow patterns of oil-water flow in horizontal pipelines mainly consist of three kinds,separated flow,dispersed flow and mixed flow (dispersion of oil in water over a water layer O/W & W) while the water percentage above 80% , which are observed by some researchers.

This method is considered to be accurate in identifying flow pattern oi gas-liquid two phase flow pipeline through example validation,which can be taken as a method to identify flow pattern in calculation of oil-gas mixing transportation process.

The computer control energy-saving system of solar heating for oil gathering and transportation creates a new energy-saving way.

An optimized mathematical model of topology optimization for stellated oil gathering and transportation pipeline network is established,in which the minimum investment is taken as objective function.
