| 摘 要： | 稠油生产出砂是油气田开发中制约产能的重要因素,高温蒸汽冲刷、沥青质的热解和水岩反应溶解是稠油热采出砂的主要原因。针对稠油开采出砂问题,分析稠油区块的出砂机制,并试验研究稠油热采注蒸汽对岩心渗透率的影响和稠油热采的出砂机制。结果表明:随着注入蒸汽量的增加,岩心的渗透率都会先下降后上升,开采时需要适当控制蒸汽流速以恢复最终渗透率到原有的80%左右;高流速下流体的流动冲刷导致地层的拉伸破坏而产生微粒的运移,破坏了骨架砂;高温导致岩石的胶结强度下降,砂粒疏松;高黏度的原油在流动中阻力大,流动所需的压力梯度大,对砂粒的摩擦携带作用也大;岩心初始渗透率低导致驱替压差大,对岩心产生剪切破坏。 |
