摘　　要：Conventional diverting techniques may not be useful,and the use of the advanced and well-documented diverting technique is needed to overcome the complexity and heterogeneity of carbonate reservoirs.Nowadays,there have been a lot of materials and techniques utilized for acid diversion.This paper aimed to consider various utilization of fiber-assisted self as the diverting system in acidifying carbonate reservoirs.One of the main reasons for its ability to overcome uncertainty is that the fiber itself is an inherent property,allowing for an automatic diversion adjustment downhole.When a media with infinite permeability,such as a perforation tunnel or natural fracture,is filled and bridged with a material of finite permeability such as degradable fiber,this creates a temporary skin to injectivity in that zone.This is a powerful concept,as it is a way,despite uncertainty from a lack of logging data or uncertainty in the data itself,of dampening the reservoir’s natural permeability contrast.It does not rely on petrophysical certainty to design a successful treatment.
