Abstract
Focusing on the leakage problem in high temperature and high salinity oil fields (reservoir temperature 1208C-1308C, formation water salinity 220000 mg/L), a gel-blocking system is proposed using a polymer and a phenolic prepolymer. Specifically, it addresses the short storage time issue of synthetic phenolic prepolymer by introducing p-hydroxybenzoic acid to modify and effectively extend its lifespan. The additional introduction of c-aminopropyl triethoxysilane (KH550) improves the wall-adhesion of this system. The proposed gel-blocking system shows good on-site application results in a western China oil field.
