Analysis Of The Composition Of Operating Costs And The Influencing Factors Of S Oilfield

In China most of the old oil along with the increase of development time has entered the late stage of development,increasing the cost of oil exploration,and gradually reduce annual oil production,economic benefit deterioration.It is necessary to control and reduce costs.To control the cost of oil,we must study the composition and the causes of changes of oil exploration,to find factors that affect the cost.The study of factors affecting the relationship between the cost of mining,providing the basis decision-making for oilfield cost control,improve economic efficiency and adjusting development plans.S oilfield in old oil fields in eastern China as the research object,collecting S oil production and development cost data.With operating cost structure analysis as a starting point,the use of Pareto and indices analysis,analysis the main cost of S oilfield operation cost from two aspects of static and dynamic.Research shows that underground operations costs,into the oil drive wages,wages and welfare,power costs is a major component of the operation of the project cost.According to statistical methods,establishing the index analysis system.Through the analysis of the main cost project changes,find each of the major factors affecting the size and cost of the project,on the basis of a comprehensive analysis of the results,the main factors affecting the cost of the project clear,find the direct cause of the impact of major changes in the cost of the project.By analyzing the strength of factors,select the working wells,injection wells,the number of wells,unit costs,annual oil production rate and water content of the main factors affecting the cost of the project.These factors affect the main cost project changing directly and affect the operation cost indirectly.Using cost analysis method to study the model relationship between factors and the operating costs.Through analysis the relationship of the various single factors and the operating costs,working wells,injection wells,unit costs,water content and operating costs changes in the same direction,annual operating cost of oil was in the opposite direction change.On this basis,analysis the impact on operating costs through multi-factor analysis to obtain a causal relationship between factors and operating costs maps and models.According to the content of the study,The influencing factors into technology,production and accounting categories,from three angles of production technology,process control and cost accounting proposed countermeasures of S oilfield operation cost management and control,for S oilfield to improve economic efficiency,reduces the cost to provide ideas.
