Study On Single Well Benefit Evaluation Of CBM Company CS Coalbed Methane Development Block

Many oil and gas fields in China have entered the middle and later stages of development cycle,and the oil price has experienced great fluctuation,which greatly affects the economic benefit of oil and gas enterprises.In particular,for unconventional natural gas enterprises such as coal-bed methane,the management mode of "emphasizing production while neglecting benefit" needs to be gradually changed,which determines that such enterprises should pay more attention to benefit development and benefit management,gas Field enterprises must bring the work of improving economic benefits into production and operation.On the basis of studying the relevant theories and practices at home and abroad,combining the benefit evaluation theory and the practice experience of single well benefit evaluation in enterprises,this paper deeply analyzes the present situation of single well benefit evaluation of CBM,through the optimization of evaluation method and decision data model,the evaluation system of single well benefit of CBM is optimized.The system is divided into four parts: determination of single well benefit evaluation index,single well cost accounting idea,single well cost allocation method design,production decision system construction.This system is a brand-new single well benefit evaluation system in CBM production evaluation,which comprehensively considers various factors affecting single well benefit,such as geological conditions,production rules,control measures rules,financial subsidies,etc.,the precise classification of single well benefit of CBM IN CS development block is realized.Through a series of comprehensive management measures and the implementation of the programs of increasing resources,saving expenses,reducing costs and increasing efficiency,this paper analyzes and compares the factors such as the production capacity that can be expected to be increased,the cost saved,and the increased financial subsidies,etc.,it has directive and practical significance to provide an effective decision-making index for the future "one well one policy" and the development direction of the whole development block.
