摘要
由于裂缝的存在,低渗透油田开发的合理注采井网的研究就变得至关重要。介绍了低渗透油田开发井网的几种主要形式即三角形反七点、正方形反九点、菱形反九点和矩形五点井网。对低渗透油田开发的合理井网进行了认真分析,指出低渗透油田开发的合理井网应该是开发初期采用菱形反九点井网,中后期再调整为矩形五点井网。在此基础上,提出了低渗透油田开发合理井网部署的几点原则。并对合理的井、排距与井网密度做了认真探讨。
Because of the existence of fractures,the research on rational injection-production well pattern for low permeability oil field becomes crucial.In this paper,several major well patterns for low permeability oil field were introduced,such as reverse triangle 7-spot,reverse square 9-spot,reverse rhombus 9-spot and rectangle 5-spot well patterns.How to select rational well pattern for the low permeability oil field was carefully analyzed.It was pointed out that the initial well pattern should use reverse rhombus 9-spot well pattern,and adjust to rectangle 5-spot well pattern in middle-late stages.On this basis,several principles to lay out rational well pattern for developing low permeability oil field were put forward,and rational well spacing,row spacing and well density were discussed.
