LIQUID COMPOSITION FOR CONSOLIDATING UNCONSOLIDATED OR POORLY CONSOLIDATED PARTICLES IN AN UNDERGROUND FORMATION AND METHOD FOR TREATING AN UNDERGROUND FORMATION PART AROUND A BORE HOLE WITH SAID LIQUID COMPOSITION

摘要

A B S T R A C TA liquid composition for consolidating an underground formationcomprises resin-forming agents including an epoxy compound and dissolvedin a solvent in a total volume concentration between 5 and 30%, and aviscosifying agent. The viscosifying agent may be a polymer, such as apolymer selected from the group of polymers consisting of isobutenepolymers, methacrylate polymers, olefine copolymers, synthetic rubbers,polyvinyl pyrrolidone and isoprene-styrene copolymer.The liquid composition may be used for consolidating a formation partaround a borehole, comprising unconsolidated or poorly consolidatedparticles and/or comprising a disturbed zone. In the latter treatment,granular particles are added to the composition.
