Study On Relation Between Cost And Profit Of Petroleum Production Of Huabei Oilfield

At present, economy globalization and global petroleum Corporations'reformation make PetroChina face serious challenge. Transformation of Petroleum Industry's increase mode needs improvement of science and technology. After reformation, PetroChina has come into the market successfully and is facing global competition. Thus, How to make Oilfield development planning economically in the market economy is a necessary problem to resolve. That is , we need to optimize oil production and investment amount in different market environment, arrange exploitation scientifically according to oilfield's actual production.Fully considering the reformation environment of the Petroleum Industry of China and aboard, the thesis study the relation between cost and profit of petroleum production through investigation and analysis, making use one of the current international cost analysis method- full cost accounting, adopting the break-even analysis and the inframarginal analysis method, combining the national cost system and the global system, analyzing the oil production and sales by means of theory of microeconomics. The thesis puts forward a model of studying on the relation between cost and profit, establishes the optimized model on basis of the optimization theory and actual data of Huabei oilfield, detailed analysis the output, investment and production flexibility at different oil price and cost.The result of the study and the optimization model will be served as support for the short term oilfield production decision-making in the market economy.
