摘要: A process for decreasing the water permeability of a subterranean rock formation is disclosed. The involves use water-soluble polymer in conjunction with an aluminum citrate preparation. can be injected into first, followed by injection Alternatively, aqueous solution comprising both and preparation formation. Yet another includes mixing dry composition preparation, then dissolving this mixture which
