    摘要： For selectively reducing permeability to water in an underground formation producing oil and/or gas, injecting into the formation a composition comprising water, at least one water soluble aldehyde compound at a concentration (by weight) of 180 to 20,000 ppm and at least one non-ionic polysaccharide at a concentration (by weight) of 200 to 5000 ppm, the concentration of aldehyde compound being higher than that of polysaccharide. The composition may be used in the water injection well or the hydrocarbon producing well and may assist in the recovery of hydrocarbons.

    摘要： The invention relates to a process for reducing or completely stopping a water inflow from a formation towards a producing well.The process according to the invention, using the injection of an aqueous dispersion of hydrosoluble polysaccharide in this producing well, blocks the water inflow without however decreasing the oil and gas flow towards this well.This process is particularly of high interest when the produced water is hot, e.g. at a temperature from 70.degree. to 130.degree. C., and/or salted, e.g. of a salt content of at least 30 g/l.This process is used for oil and/or gas production.
