Gel compositions that form a composite organic-inorganic gel system for eliminating leaks and blockages during well drilling have been proposed and investigated. The three types of gels have performed well at different stages. Based on the three types of gels, an organo-inorganic composite gel system was constructed and the clogging ability under constant and varying pressure was evaluated.
