A common Web GIS framework was designed for the long transmission oil & gas pipeline. A digital pipeline Information Management Systems (IMS) was developed on the ArcGIS platform, which was based on VB.NET, Javascript, Microsoft SQL Server and computer aided analyze technology. In the case of licensed, the functions were realized in the designed system, which concluded sharing space information, map zooming in and out, map moving, diagram layer control, visiting viewdata, searching information, special subject analysis. The systems can serve the whole management and improve work efficiency in the long transmission oil & gas pipeline, and it is one of the forcefully assistant tools in managing pipeline department.

For gas pipeline, simulating the working condition was necessary in order to work safely and economically and manage rationally. Some gas pressure was up to 10 MPa in the pipeline, in which the result by equation for ideal gas has the greater error. L-E-E equation was applied to solve the physical parameters such as the compression factor, practice gas density, specific heat, adiabatic index, entropy, enthalpy and so on. And the program was compiled to calculate the properties. The calculate results show that L-E-E equation is much accurate and can be applied widely in the practice.

The Product Pipeline Optimization Based on IPGA

CUI Yan-yu, WU Ming*, ZHANG Guo-zhong

Abstract （382）

PDF （1010KB）（223）

The integer which was coded partheno-genetic algorithm (IPGA) will be used in the optimization of products pipeline pump distribution program. The rotation speed of pump was regarded as the decision-making variable. The optimization results were formed into chromosomes by using integer coding solution. Corresponding genetic methods and adaptation function were designed, and data of the western pipeline was used for verifying and calculating. The result shows that IPGA is feasible on product pipeline optimization.
