| 摘 要： | 缝洞型碳酸盐岩油藏储层具有多重介质特征,储集体在空间分布上具有不连续性,油水关系复杂,流体渗流机理与砂岩油藏有本质的区别,造成油田开采难度大.注水替油是在油藏依靠自身能量无法达到自喷,并且在机抽都无法举升原油至地面的情况下,通过井口注入地层水,使得油藏能量提升,重新具有自喷能量的一种技术.针对缝洞型碳酸盐岩油气藏的注水替油开发技术还处于探索阶段,尚无普遍适用的成熟技术可以直接应用.从大量的开发实践看,对油田的动态预测和分析,应当在将油藏进一步细分为缝洞单元的基础上进行.为了研究缝洞型油藏流体流动机理及注水替油开采机理,找到一个适合缝洞型油藏合理开发的方法,针对孤立溶洞实际特征,建立物理模型,实验研究其生产动态特征,结合现场注水替油生产,从无因次产量、无因次井底流压、含水率变化曲线得出注采动态变化规律.

| Abstract: | There are multiple media characteristics in fracture-cavity carbonate rock reservoir,its accumulative bodies are discontinuous in spatial distribution,the relationship of oil and water is complicated,there is an essential difference between the flowing mechanisms and the carbonate rock and sandstone reservoirs,which brings about difficult production.When gush can not be done by means of oil reservoir itself energy,and pumping can not lift crude oil up to surface,the water injection to replace oil is carried... |
