Abstract: Based on practice of exploitation in the Shengli oil field,a method of selecting the optimum well spacing of a development object ia presented.Applying the principles of engineering economics of petroleum industry,the effect of such essential elements as rate of production,rate of recovery,projected years of development,production cost,result of investment,net income of production enterprise,oil price,labour productivity etc.on rational well spacing is analyzed.As to the choice of an optimum oil field development plan,the application of value engineering in the quantitative synthesis of geology,oil field development and economic factors is expounded.The paper is concluded with an example of determining the maximum acceptable water cut,the minimum reasonable daily crude output of a single well,the number of years of oil field development and its ultimate recovery.

摘要： 本文以胜利油田的一个油田为实例,阐述了一个开发单元的合理井网密度的选择方法。应用油气田开发工程经济学原理,逐项分析采油速度、原油采收率、开发年限、采油成本、投资效果、采油企业纯收入、原油价格、劳动生产率等主要因素对合理井网密度的影响。在油田开发方案选择时,如何应用价值工程法,定量地综合各种地质、开发和经济因素,选择最佳方案。最后,以被选方案为例,说明了最高允许含水百分数、最低合理单井日产油量、开发年限和最终采收率的确定方法。
