Изобретение относитс к средствам интенсификации добычи природного газа и газового конденсата, а именно к пенообразующим составам, предназначенным дл лшсвидацин закупорок эксплуатащюнных скважин пластовой и конденсационной водой, газовым конденсатом , шламом.The invention relates to the intensification of the production of natural gas and gas condensate, namely to foaming compositions intended for the completion of blockages of exploitation wells by reservoir and condensation water, gas condensate, sludge.

Товарна форма этого продукта не известна 1. .j,A method is known for removing liquids and particles from squamous trunks with a 3-hydroxyalkanesul-foaming agent. Sodium and potassium phonates of the Ciz-C | 4 fraction, JVL5 are suppressed by the sulfonation products of α-olefins with sulfuric anhydride gas, i.e. a-olefin sulfonates. The product form of this product is not known 1. .j
Недостатками данного пенообразугои го состава вл ютс то, что олефиносульфонаты недостаточно устойчивы в водных средах с повышенной минерализацией и реасо утрачивают пенообразующую способность при содержании солей кальци и магни свыше 2,5-The disadvantages of this foaming composition are that the olefin sulfonates are not sufficiently stable in aqueous media with increased mineralization and reaso lose their foaming ability when the content of calcium and magnesium salts exceeds 2.5-

Alkyl ethoxy sulfates are resistant to mineralization and are capable of producing a stable foam in the presence of hydrocarbons and particles breeds 12).
Однако iix можно использовать в качестве пенообразовател лишь при малых (менее 1,2 м/с) 1шнейных скорост х газа в скважине . Как показали испытани , при больших скорост х газа пена, полученна на основе алхипзтоксис)01ьфатов, рветс и вынос жидкости из скважины резко снижаетс . Товарна форма этого продукта не описана. В указанном составе не приводитс дополШ1телып 1х добавок, которые могли бы улучшать аенообразуюшую способность алкилэтокHowever, iix can be used as a foaming agent only at low (less than 1.2 m / s) 1 external gas velocities in the well. As shown by the tests, at high gas velocities, the aliphattoxis-based fossil-based foam, the rwets and the outflow of fluid from the well decrease sharply. Product form of this product is not described. In the composition indicated, there is no addition of Schistelip 1x additives that could improve the aelo-forming ability of alkylalkoxy.
