Research On Oil And Gas Pipeline Integration Of Underground And Ground Route Selection Method Based On GIS

Oil and gas pipelines are not only convenient for transportation of oil and gas,but also important for national security and economic construction.Not only involves the underground oil and gas pipelines buried pipeline section,and including the ground road part of operational security,oil and gas pipe line selection is an important part of the entire oil and gas pipeline construction,pipeline construction is directly related to the rationality of the concept of cost of manpower,material resources and time,therefore,in order to save the project resources,facilitate the construction and convenient operation and maintenance,it is necessary to improve the demand for oil and gas pipeline selection.Based on this,this paper studies the underground integration of oil and gas pipeline based on GIS technology.(1)Of the various factors influencing the pipeline has carried on the comprehensive analysis in detail,finally choose the terrain,geology and geophysics three factors as the main influence factors of oil and gas pipelines intelligent line selection,including terrain factors are divided into elevation and slope of two factors.(2)Using the analytic hierarchy process(AHP)and expert consultation method to determine the weighting factor of line selection factors,the digital topographic map,object classification and regional geological map grid overlay processing,road line selection integrated cost distance model is established,using the spatial analysis function of ArcGIS finally reached the optimal route.(3)Finally after instances of this paper put forward the single factor of line selection model and multi-factor comprehensive line selection model has carried on the experiment and analysis,experiments show that using GIS technology to realize the automation of oil and gas pipeline routing requirements,can be used widely in practice.
