Research On Risk Management Of Oilfield Exploration And Development Investment Projects

As the "blood" of modern industry,petroleum resource plays an important role in the world economy,and has important resource value and strategic significance.However in recent decades,the growth rate of oil supply capacity growth rate relative to the needs of the people of ability to slow,resulting in oil and gas prices rising,the contradiction between oil supply and demand have become increasingly prominent.Thus,it is necessary to continue to strengthen the oil and gas exploration and development efforts.Investment risk research is mainly on investment risk identification and countermeasures research,is in the task implementation insight into and find all kinds of potential risk in the investment process,and on every possible risk strategy of coping research.The investment risk of oil field exploration and development in the early stage of investment is studied in this paper.The risk for oil exploration and development of sorting and recognition system,and study of coping strategies from the perspective of coping,in the implementation stage of the project to keep the project the smooth progress of,and carry on the effective risk control of potential risk,to protect the interests of investors.First of all,the paper expounds the realistic background of the exploration and development of oil field,the research status of the domestic and international related research,and summarizes the relevant theories,and discusses the relevant theories which need to be applied in this paper.Secondly,through literature analysis statistical method,questionnaire survey method of the project pre investment may exist risk recognition and summarized and the risk causes are analyzed.The oilfield exploration and development investment risk index system is established.Again,in group of risk factors have been identified based on the need to focus on risk factors were determined.The determining process in this paper the calculation method used is the solution of high order matrix to the largest eigenvalue of the quasi Newton method,including Broyden algorithm,BFS algorithm,the DFP Algorithm.Finally,the possible risk factors were studied,and the conclusion of the whole paper was given.
