A method of alignment Profile injectivity in injection and water shutoff in producing wells

摘要

Method alignment profile injectivity in injection and isolation of water inflow in production wells comprising the injection into the formation of the insulating composition of the polymer-based crosslinker and water as an insulating composition using a dispersion in water of carboxymethyl cellulose, polyacrylamide and crosslinker, characterized in that it further comprises a chelating agent, and as said particulate poliakrialamid polyacrylamide is used at a ratio, wt.%:
