... дополнительные компоненты (спирты, ПАВ и т.д.), которые способствуют более полной сорбции реагента на пласт. The article describes the first experience of protecting horizontal wells from gypsum scaling, using the inhibitor squeezing technology. Various mechanisms of the inhibition of gypsum deposits by phosphonate inhibitors are determined. Materials and methods Inhibitors, intended for protecting wells from gypsum sediments, were selected,...

... скважин пласта ВЧ2 ВЧНГКМ. The paper discusses the features of scaling in the wells and the hole-bottom region specific to the Verkhnechonsk field. On the natural core samples filtration experiments are conducted to detect the effect of gypsum deposits in the reservoir on its permeability and to find permeability recovery techniques. For a number of scale inhibitors carried outa test of their effectiveness both static and dynamic methods. Their adsorption-desorption properties were determined....
