Abstract: SCADA and GIS-based control system of oil & gas pipeline can effectively modernize the control management of oil/gas pipeline and speed up the realization of digitalization launched over the oil/gas pipelines all over the country. According to the feasibility of complementary application between SCADA and GIS technology in the running process of the pipeline control, the basic framework of the system has been set up, that is, the data processing of SCADA and GIS has been completed by the same platform, accompanying with static and real-time data processing under a higher efficiency, and finally, users interview the space and real-time data through the same interface to order and make decision to control the operation of oil/gas pipelines. The basic functions of this system are consisted of location visualization of leak detection, pig tracing/locating and displaying, batch tracing/positioning and displaying, emergency response and decision-making, acquisition, analysis and statistics of information, multimedia for pipeline and facilities, the alarm and highlight display of parameters, on-line display of status parameters and processing and printing of schematics, etc.. Some issues exist in the interface processing and data storage in realizing overall management about the dynamic/static data, which furthermore need to investigate and improve.
