Aiming at improving the acid fracturing effect of carbonate reservoirs at high temperatures, reaction kinetics and acid fracture conductivity of five high-temperature sustained-release acids were investigated. The experimental results show that viscous acid, gelled acid II, authigenic acid I, and ge...
