Research On Economic Benefit Evaluation Of JD Oilfield Block

With the continuous improvement of recovery degree.Currently most of the oil fields in Bo hai rim region has entered a post-mining,and subjected to resource constraints,institution,market and other factors,cost control is becoming more and more difficult,unprecedented pressure is laid on cost reduction and efficiency increase.To enhance the input and output efficiency of oil blocks,maximize the efficiency of oil blocks in life cycle and achieve the goal of resource utilization,oilfield enterprises have begun to implement block input-output management.Meanwhile,it directly affects the development status of the entire field that whether the benefit valuation is accurate or not.So how to evaluate the effectiveness of oil blocks has been the common concern in process of oil block input-output management of each oil enterprises.Thus an effectiveness evaluation system is required to be established to match oil block cost management.This paper summarizes systematically on the basis of theory and practice elated to reservoir management,Single well benefit evaluation,block input and output management and Measures benefit evaluation at home and abroad,based on actual production and operation of JD oil company,in line with the goal of "hard increase storage,stability and benefit".proceed from the level of oil blocks,based on cost-benefit principle,analyzing benefit hierarchically and from multiple perspectives,constructing the evaluation system of oilfield benefit,the system consists of three parts,including the evaluation of block single well benefit,block production management level,measures of economic performance evaluation.among this,the evaluation of production management level is the basis of block-effective management,the evaluation of single well benefit is the extension of the system.Through applying the evaluation system,this paper will propose targeted the management countermeasures of improving benefit of oil blocks and the safeguards for specific applications of the evaluation system.
