摘　　要：以胜利单家寺油田单 6东超稠油储层为例 ,利用高温高压动态物理模拟流程研究了蒸汽凝析液对超稠油油藏储层的伤害 ,得出主要注汽工艺参数对储层渗透率的影响程度和规律 ,在此基础上对现场注汽工艺参数进行优化 ,并筛选出适合该区块的热采油层保护添加剂 。Taking Shan6 East super heavy oil reservoir in Shengli Shanjiasi oilfield as an example, the damage of steam condensate to reservoir has been studied through high temperature high pressure dynamic physical modeling. The influence of major steam injection parameters on reservoir permeability is also given. Based on these, field steam injection parameters have been optimized, and reservoir protection additive suitable to this block has been screened, thus providing important reference for reservoir protection.
