整体调剖技术在超低渗油藏早期开发中的应用

Overall up of profile control technology in low permeability reservoirs early development of application

超低渗透油藏,微裂缝发育,注水开发后,油藏含水上升快,水驱效率低。针对这种开发矛盾,开展以注采双向调整为核心的油藏整体调剖技术研究,应用了油藏描述成果、配套裂缝识别技术,优选适合的调剖剂和措施方式等,及时对F油田长6油藏进行整体治理,有效提高了注入水波及体积和水驱采收率,开发指标变好,与调剖前相比,地层压力保持水平上升3.7%,综合含水率下降12.1%,自然递减率下降4.1%,综合递减率下降6.7%,单井产能提高0.1t,油藏整体开发效果良好。

Low permeability reservoirs,micro fracture development,after water injection,the oil reservoir water rising fast,water flooding efficiency is low.Aiming at the development contradictions,conducted injection-production two-way adjustment as the core of the reservoir up of profile control technology research,the whole application results of reservoir description, complete fracture identification technology,the tone for optimizing suitable profile control agent and measures to F,timely way long 6 reservoir in oil,and improves the whole management injected water sweep volume and water drive process,developing index changing, compared with adjustable dissection,formation pressure keep before the increased level 3.7%,comprehensive moisture content,natural decline rate drop down 12.1%rate dropped 4.1%,comprehensive 6.7%,the single well productivity improve 0.1 t,reservoir overall development effect is good.
