| 摘 要： | 通过室内一维、三维物理模拟实验和油藏数值模拟,系统研究了稠油油藏注蒸汽后期转火驱开发的机理和相关油藏工程问题。研究表明:注蒸汽后期地层次生水体的存在会降低火驱燃烧带峰值温度、扩大热前缘波及范围,其干式注气过程同样具有湿式燃烧的机理,由次生水体造成的高含水饱和度对单位体积地层燃料沉积量、氧气消耗量等燃烧指标影响不大。三维物理模拟实验火驱最终采收率可以达到65%,火驱过程中有明显的气体超覆现象,油层最底部存在未发生燃烧的结焦带,但结焦带中大部分原油已被驱扫,剩余油饱和度低于20%。结合稠油油藏注蒸汽后期的储集层特征和现有井网条件,对火驱驱替模式、井网、井距和注气速度等进行了优化,并筛选了点火、举升、防腐等关键工艺技术。研究结果应用于新疆H1井区火驱矿场试验中,目前矿场试验初见成效。图10表4参20

| Abstract: | The mechanism and problems associated with development engineering of fire-flooding in post-steam-injected heavy oil reservoirs was studied using 1D & 3D physical simulation experiments and reservoir numerical simulation.The temperature of combustion zone decreased and high-temperature zone enlarged because there existed secondary water formed during steam injection,which could absorb and carry heat towards producers out of the combustion front during fire flooding,but high saturation of water in layers cau... |
