摘　　要：在分析油田井网密度与最终采收率关系的基础上，根据收支平衡的基本经济原理，导出了已开发油田打加密调整井的合理井网密度和极限井网密度的一种求解方法。应用该方法在不同油价下对F油田分区块进行了测算、分析，指出了中区、东区是F油田打加密调整井的主要地区，为合理高效开发好F油田提供了依据。Solving methods of rational well spacing desity and critical well spacing density of infill producers in developed oil field are derived by using the basic economic principle of revenue and expenditure balancing and on base of analysis of the relationship between well spacing desity and ultimate oil recovery． This method is used to estimate and analyze each block in F oilfield under different oil prices． The central and east blocks are the favorable areas for infill drilling in F oilfield． These study results provide basis for rational and highly effective development of F oilfield．
