The invention relates to a method for stabilizing the gas flow in water- bearing natural gas deposits or reservoirs which produce at least 50 l of water per 1000 m3 (Vn) of extracted natural gas. According to said method, a dispersion comprising the following components is injected into the water-bearing rock: A) an organosilicon compound as the dispersed phase; B) a hydrophilic dispersion agent, which can be mixed with water, and, if needed, C) a dispersing additive.
L'invention concerne un procédé permettant de stabiliser le flux de gaz dans des gisements et des réserves de gaz naturel aquifères, qui produisent au moins 50 litres d'eau pour 1 000 m<3> (Vn) de gaz naturel extrait. Selon ledit procédé, on injecte dans la roche aquifère une dispersion contenant les composants suivants: A) un composé d'organosilicium, qui constitue la partie dispersée, B) un agent de dispersion hydrophile, qui peut se mélanger avec l'eau, et, éventuellement, un additif dispersant.
