摘　　要：低渗油田开发方案设计必须同时考虑经济合理井距和技术极限井距。现场可进行几种不同井距下的注采试验,然后根据各种井距下采油井的动态情况来定性判断低渗透砂岩油藏技术极限井距。如果技术极限井距大于或等于经济合理井距,则该井距就是低渗透砂岩油藏的合理井距,油藏工程方案就可据此部署井网。如果技术极限井距小于经济合理井距,则该油藏必须经改造后才能进行开发。Economical well spacing and technical limit well spacing must be considered when making up development plan for low permeability sandstone reservoir.It is recommended to conduct injection-production tests under different spacing to decide technical limit spacing according to production well performance.If the technical limit spacing is bigger than or equal to the economical spacing,it would be feasible in low permeability sandstone reservoir and reservoir engineering plan can be scheduled on this basis.Otherwise the reservoir must be stimulated prior to recovery.
