摘　　要：针对洗象池群白云岩储层酸压工艺参数研究,采用酸液指进可视化物理模拟装置研究多级交替注入下的酸液指进行为,以分形维数等3个参数评价酸液指进形态进而优化多级交替注入参数。优化后的酸压施工参数经现场试验后,增产效果达到预期,为洗象池群白云岩储层的酸压工艺提供了理论和试验基础。In view of the research on acid fracturing process parameters of Xixiangchi Group dolomite reservoir,the acid fingering behavior under multistage alternate injection was studied by using the acid fingering visual physical simulation device,and the acid fingering morphology was evaluated by three parameters such as fractal dimension,and then the multistage alternate injection parameters were optimized.The optimized acid fracturing construction parameters have achieved the expected stimulation effect after field test,providing a theoretical and experimental basis for acid fracturing technology of Xixiangchi Group dolomite reservoir.
