I. Introduction
The pipeline of oil-transportation covers ten cities at the length of nearly a thousand kilometers. The pipeline has already been used for 30 years. The geographical environment is complexity. The pipeline corrosion, illegal covers on pipeline and oil-stealing situation is serious. However, it makes more use of the information of the pipeline by drawings, charts, cards and other forms of record keeping. Such manual management mode and management has led to inefficient management, data update and poor resource sharing has been unable to meet the rational planning, scientific management, security, transportation, quality requirements [1].
