Research On Layout Optimization Of Overseas Assets Of China's Oil&Gas Companies

With the rapid economic growth,domestic oil and gas production growth is far unable to meet the needs of the rapid development of the national economy,the contradiction between supply and demand have become increasingly prominent,the oil and gas imports are rising,foreign dependence is strengthened.Therefore,the state puts forward the strategy of "going out",access to oil and gas resources from overseas oil and gas resources in the country,to supplement the domestic economic and social development demand for oil and gas.China's oil companies play an important role in the development of its overseas oil and gas assets,is the basic guarantee for China's energy security.After defining the concept of petroleum enterprises overseas asset allocation and asset optimization,analysis of the relationship between the factors of petroleum enterprises overseas assets layout,construct a theoretical framework for petroleum enterprises overseas assets layout optimization;then,the path and methods of overseas oil and gas business layout of typical big international oil company,combined with the characteristics of our country petroleum enterprises overseas assets layout,we build a dynamic model of the layout optimization of petroleum enterprises overseas assets;and finally to China Petroleum Enterprise S company as an example,the layout of its overseas assets are positive,the overseas assets layout optimization.The research content and the innovation points of this paper are as follows:1,theory framework of overseas oil and gas assets layout.The first concept of petroleum enterprises overseas assets layout definition,determine the factors related to overseas assets layout contains,such as conventional oil and gas and unconventional oil and gas proportion,the project of regional distribution,production scale,product structure,the ratio of the upstream and downstream oil and gas ratio,sea land service proportion;then,according to the energy security in the theory of the 4A concept,the availability,accessibility,affordability,acceptable ability from four aspects such as macro environment,to overseas oil and gas projects in oil and gas company ability.economic level and other aspects of the main factors affecting the overseas oil and gas assets layout;then,the general location theory industrial layout is based on the relationship between the impact analysis,geographic location,origin of raw materials,oil and gas transportation volume and other factors,and the modern portfolio theory from the risk and income angle analysis of overseas oil and gas assets portfolio problem.Finally,according to the definition of oil and gas projects,the theory framework of overseas oil and gas assets layout from three aspects of the project distribution optimization,economic optimization,business structure optimization.2,construction of the dynamic oil enterprises overseas asset layout modelFirst,from the three aspects from the project distribution optimization,economic optimization,business structure optimization,optimization approaches,the typical International Oil Co way was analyzed,the main influence factors of overseas assets layout of the oil company;then,based on the characteristics of China's oil companies,to build the index system of petroleum enterprises overseas oil gas assets layout optimization.On this basis,analysis of correlation between each factor and the optimization goal taking into account the petroleum enterprises not only need to safeguard the country's oil and gas supply,but also consider their own economic interests of multiple targets,using multi-objective planning method,constructs the dynamic petroleum enterprises overseas asset allocation model.3.Design optimization of China Petroleum Enterprise Assets layoutFirstly,typical of China's oil enterprises S company investment distribution characteristics and trends are analyzed,on this basis,using a dynamic optimization model for petroleum enterprises overseas assets layout,from three aspects which are the target of energy security,economic benefit target optimization,optimization of regional layout optimization of combination scheme of S company's overseas assets project layout,and based on the multiple objective programming model,considering the above three kinds of target,put forward S the next five years the company's asset allocation optimization scheme.Finally,combined with the characteristics of overseas assets layout of Chinese oil company,proposed the strategic choice of China's petroleum enterprises overseas asset allocation and optimization strategy.
