Long-distance transportation oil&gas pipelines are usually buried underground,they can unavoidably be corroded due to the soil environments around them.

Development of the software for the risk probability analysis of long-distance oil/gas pipeline;

Traditional monitoring control means of long gas-transferring pipeline with manual recording and gradual reporting,is not adapted to the requirements of the rapidity of production scheduling,and the strategy of city s digital and informational development.

The research actualities of detecting methods of leakage of long-distance oil and gas pipeline are introduced in this paper,and the advantages,disadvantages and applications of the detecting methods above are analyzed and compared in detail.

This paper introduces design and realization of the geographic information system for long-distance oil and gas pipelines using C# as programming languge and ArcGIS Engine as development tool.

Transient simulation analysis on magnetic flux leakage detection of cracks in long-distance oil and gas pipeline
