THE SPATIAL STRUCTURE OF THE WORLD'S OIL FLOW AND ITS FLOW FIELD CHARACTERISTICS IN THE BEGINNING OF 21st CENTURY
基于全球石油供需格局，将石油流动区域分为流出、自给和流入三类，并依据流动性比率划分功能类型，运用场论分析石油流场的动力与阻力，划分出六大流场，建立石油流动的轨迹框架。
The oil flow within the scope of the global is a historical phenomenon which has wide region,large scale characteristics and tremendous social and economic impact.Its operation morphology has obvious flow field characteristics.In order to analyze the space characteristics of world's oil flow in the beginning of this century based on the pattern of world oil supply and demand,the oil flow areas are divided into 3 balancing types: flow-out type,self-sufficiency type and flow-in type.And in accordance with the liquidity ratios,the oil flow-out areas and flow-in areas are divided into 2 function types: input center and output center.On this basis,the power(potential difference) and resistance(distance) of oil flow field are analyzed based on the field theory,and according to oil’s potential value pattern,the world's oil flow regions are divided into 6 flow fields: North America flow field,Central and South America flow field,Africa flow field,Middle East flow field,Europe and Eurasia flow field and Asia Pacific flow field.In the meantime,the 2 main tracks of oil flow in and between these flow fields: shipping routes and petroleum pipelines are analyzed,and the trajectory framework of the world's oil flow is established.
