Research On Long-Distance Natural Gas Pipeline Distribution

Development of China’s natural gas industry for our country to achieve sustainable development and urbanization play an important role. For natural gas resources are very unevenly distributed in our country. How to exploit natural gas transported to using place had become a problem that have to be solved. Using many modes of inland transport, the long-distance pipeline transport will gradually became the main way of transporting natural gas development and utilization. Because long-distance gas pipeline network structure is complex and diverse characteristics of such technology through the development of rational angle of natural gas pipeline network to run the program had become a difficult problem to solve.In order to achieve better economic and social benefits, analysis in-service operation of natural gas pipeline network system-modeling give the best solution based on the data, information and production operation. Thesis based on Branched Gas Pipeline Network and West-East Gas Pipeline: First, based on domestic and international data collection and field research.On the part of the development process and natural gas industry are introduced, for the existing natural gas operation, Collection and analysis. Secondly, by collecting a large natural gas pipeline operations specifications and performance data, information, model a General mathematical for Branched Gas Pipeline, and introduced the initial conditions and constraints. Then, according to the distribution of West-east pipeline, compressor stations, abstract and simplifies the configuration, set up a specific mathematical model. By studied the operation and management of the key factors in the natural gas pipeline, manage the pipeline economics to quantify. Analyzed the reduced efficiency caused by the pipeline factor. At last, by combined gas line mathematical model, propose control measures to achieve the overall efficiency of network operation, to temporary increase peaking capacity.Provide a reliable basis for scientific decisions on pipeline operation management, to maximize revenue corporate earnings, and guide pipeline operations, renovation, maintenance and other operation management.
