摘　　要：高黏度酸液酸岩反应时流体的流动情况比较复杂,很难用实验手段直接测量。采用流体计算力学(CFD)软件FLUENT对高黏度酸液在反应釜内部的流动情况进行模拟。结果表明:对于高黏度酸液而言,随着转速的增加,壁面速度损失愈加增大。得出了转速与壁面速度损失的关系式和转速与壁面速度的关系式,以此两关系式可以较为精确地计算各转速下壁面速度损失与壁面速度;将模拟结果与地层裂缝联系起来,得到了施工排量与实验装置转速的关系,从而优化实验设计。捕捉到了模拟装置反应釜内部流场的流动细节,为以后的实验提供了参考;并对反应釜的设计改造提供了理论依据和指导方向。The flow situation of high-viseosityacid is very complex in the acid-rock reaction and it is difficult to be measured directly by the experimental means. Computational fluid dynamics（CFD） FLUENT software is applied to simulate the flow situation of high-viscosity acid in the reactor. The result showed that as the rotating speed in- creased, the velocity loss on the wall increased even more for the high-viscosity acid. The formula is obtained be- tween the rotating speed and the velocity loss on the wall, and the formula between the rotating speed and the veloc- ity on the wall. So, the velocity loss on the wall and velocity on the wall can be calculated accurately by them. Combined simulation results with formation fractures, the relationship between the pumping rate and the rotating speed of experimental apparatus can be got, so the experimental design can be optimized. This research has ob- served the flow field details in the reactor, providing a reference for future experiments, along with a theoretical ba- sis and direction, for reactor transformation design.
