Abstract Addressing the problems found in some wells carbonate reservoirs of Tahe and Shunbei blocks, such as wide natural fractures large leakage, an efficient temporary plugging agent is developed to effectively seal up leaky without affecting flow path after acid fracturing. The prepared by crosslinking organic zirconium crosslinker with starch-grafted polyacrylamide. Among materials, polyac...
