摘　　要：双河油田扇三角洲上倾部位油藏埋藏较深、低孔低渗,由于井距大,注采不完善等导致开发效果差。针对地质特点及开发中存在的主要问题提出了改善开发效果的对策,即:开展了地质综合研究、加密先导试验、井网优化、高压增注、储层改造、油层保护等工作,使该部位增加地质储量214×104t,采油速度由1992年的0.50%提高到2003年的0.99%,采收率提高20个百分点。The Reservoirs in updip block of Shuanghe oilfield tim delta are deep with low porosity and low permeability.The long distance of well and injection-production faultiness lead to the poor development effect, This paper puts forward the countermeasure to improve development effect. ,such as geological comprehensive research,increasing precursor experimentation,optimizing well patterns,enhancing water injection by high pressure,reservoir alteration,reservoir protection,etc.,which makes the geological reserves increase 214×10^4t.The oil recovery rate raises from 0.50 percent in 1992 to 0.99 percent in 2003 ,and recovery ratio increases 20 percentage points.
