    摘要: 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 the 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.
