Therefore, the acid wormhole propagation mechanism study and the novel calculation model for the acid leak-off in the acid fracturing is more important.
酸蚀蚓孔扩展机理研究和考虑酸蚀蚓孔滤失的酸压计算模型研究则显得尤为重要。
The acid wormhole leak-off volume is concerned with the pumping rate, the acid viscosity, the acid concentration, acid injection time and the formation physical property.
酸蚀蚓孔滤失量与排量、酸液粘度、酸液浓度、注酸时间以及储层物性有密切关系。
The main reason why the bad influence of acid wormhole on acid fracturing execution is hardly controlled in a long time, is that we do not master the acid wormhole propagation mechanism.
长期以来难以控制酸蚀蚓孔对酸化压裂施工造成的不良影响，其主要原因是不明确酸蚀蚓孔发育机理。
