摘　　要：“九五”末期,胜利油区整体进入特高含水开发阶段,剩余油富集区分布异常复杂,各类型油藏挖潜难度加大。根据这一阶段的开采特征,及时转变油田开发调整思路,在发展完善已有技术的基础上,对整装构造、断块、低渗透、热采稠油等不同类型油藏采用了细分韵律层、水平井挖潜及井间加密等新的开发技术措施,对154个单元实施调整,新增产能448×104t,已提高采收率达1.6%,极大地增强了老油田稳产基础,为相同类型油藏开发后期进一步提高采收率提供了开发思路及技术方法。Improvement of reservoir development becomes more and more difficult for the whole Shengli petroliferous province has been gone into extra high water - cut development period and remaining oil distribution becomes more complex at the end of ' nine-five'. One hundred of fifty - four blocks, categorized into packaged conformation, fault block, low permeability and viscous crude steam stimulation,are adjusted according to the production performance at this stage. Those applied methods are refinement of rhythmic units, horizontal well, well pattern infill and some other new development technologies. Production capacity is good after implement. It is the fact that new incremental productivity is 448×104t and enhanced oil recovery 1. 6% (OOIP). The stableproduction foundation of developed oilfields is strengthened and it provides development idea and technology for enhancing oil recovery further for the same type of oil reservoir.
