Construction And Application Of Oil Field Development Management Decision Support System

As the low and medium oil prices in the international oil market has been into normalcy,China's oilfield blocks have gradually entered the mid-to-late period of production and development.The new internal and external environment determines that the production and operation of oilfields in China must be considered as careful accounts,effective profits and losses,and future accounts.Oilfield companies face some problems in their development and management decisions: Do those low efficiency single well,unit and block need to stop production? Do they have to take some operating measures? Which operating measures gain the best benefit for a specific job object? Which development solution is most effective for a development unit? Do they have to hit a new well? The answer to these questions is the specific content of oilfield development and management decisions.To make scientific decisions on the above issues,it is not enough to consider technical feasibility only,We must also consider the feasibility of benefits.Considering not only past historical data,but also future trends.Under this background,it is especially necessary and significant to establish a scientific,rational and feasible decision support system for oilfield development and management.This paper first systematically expounds the theory of oilfield development,reservoir management and benefit evaluation,makes a comprehensive review of the research achievements made by Chinese and foreign scholars in oilfield development and management decision-making and oilfield development benefit evaluation,then it analyzes the construction foundation of oilfield development management decision support system,including the construction of single-well unit benefit evaluation system,the construction of input-output basic database and the application of numerical simulation technology in oilfield development.On the basis of theoretical analysis,technology and data foundation analysis,this paper constructs the overall framework of oilfield development management decision support system from the aspects of basic idea,basic idea and basic elements.From the perspectives of decision-making body,decision object,decision scenario and decision-making plan,Decision-making basis,decision-making methods and decision-making procedures and other aspects,this paper design the specific content of oilfield development and management decision support system.Finally,the block of xx reservoir in Shengli Oilfield is selected.Based on the recent data of the block and the output of numerical simulation technology,the decision support system is used to calculate the relevant decision index for the production of the block,provide support for production and development decision-making and realize the concrete application of oilfield development and management decision-making system.
