Feasibility Study On Pilot Production And Utilization Of Natural Gas In X Area Of Longdong Gas Field

The construction of natural gas utilization project in longdong regions can optimize the energy structure of longdong and improve the environment for attracting investment of local and industrial parks,which is of great significance for promoting the optimization of energy structure and the adjustment of industrial structure and driving the rapid development of industrial economy.Diverting natural gas from gas fields can not only reduce the consumption of crude oil and increase the commodity amount of crude oil,but also increase the sales volume of natural gas and promote the development of oilfield.This paper adheres to the basic principles of "economic and practical,reliable operation,safety and environmental protection",reduces the investment in ground construction and improves the efficiency.Through a comprehensive market research,this paper analyzes the resource situation and market situation in Longdong region,and predicts the future market demand for gas and resource risk.Through the analysis of the adaptability of pipeline network and the balance of supply and demand in the future market,through the comparison of schemes,the lines trend,pipeline specifications and gas transmission pressure are selected.First of all,according to the actual landform and local conditions in Longdong area to compare the local scheme,choose the best route to the scheme,according to the specifications of the pipeline design.Secondly,PIPELINE STUDIO is used to simulate the operation condition,pipeline adaptability and accident condition of the new pipeline network.According to the principle of selection of pipe type,the pipe type and steel grade are determined on the basis of strength calculation,and the strength and stability are checked.Pipeline anticorrosion was carried out according to the specifications,and TGNET was used to simulate the scheme with or without inner coating for comparison,and the outer coating was supplemented by cathodic protection combined protection measures.Finally,the project strictly abides by the gas pipeline engineering design specifications for the complete design of the project.The research on the technical scheme of this project has important guiding significance for the design of natural gas utilization project in Longdong region.
