摘　　要：从宝北区块井网型式、注水方式、水驱控制及动用程度、油水井供液能力、驱动指数、油井见效见水等方面分析了宝北区块注采井网适应性,指出了环状注水方式和注采井距不合理是目前井网不适应油田开发需要的原因所在,并在此基础上提出了增布内部注水井点、缩小注采井距、改环状注水方式为排状注水方式、加强内部注水、加大分层改造力度等改善开发效果的措施及建议。Adaptability of well patterns in Baobei block are analyzed in respects of the types of well pattern, water-injection methods, waterflooding control and the ratio of producing reserves, fluid supply capacity of producers, drive index and so on. It points out that circle flooding mode and the irrational flooding well spacing are the causes of current well patterns being not adaptable to the needs of oilfield development. Some measures and proposals are presented to improve development effects including allocating additional internal water injectors, reducing flooding well spacing, replacing circle flooding mode with line flooding mode, enhancing internal water injection and strengthening layered stimulation.
