Изобретение относитс  к нефтедобывающей промышленности, в частности , к составам дл  борьбы с обводнением нефт ных и газовых скважин при разработке нефтегазовых месторождений .The invention relates to the oil industry, in particular, compositions for combating watering of oil and gas wells in the development of oil and gas fields.

Известна гидрофобна  водонефт на  эмульси  дл  ограничени  водопритоков в скважины 1 J.,Known hydrophobic vodoneft on emulsion to limit water inflows in wells 1 J.,

Однако эта эмульси  характеризуетс  эффективностью изол ции плаСтовых вод.However, this emulsion is characterized by the effectiveness of isolating plastic waters.

Известен также состав дл  иэолйции притока пластовых вод в скважину , содержащий водный раствор диэтаноламида жирных кислот с 10-16 углеродными атомами и дисперсн; фазу нефть . Водонефт ную эмульсию получают эмульгированием нефти в водном растворе диэтаноламида жирньгх кислот 2 .A composition is also known to isolate the flow of formation water into a well containing an aqueous solution of fatty acid diethanolamide with 10–16 carbon atoms and dispersion; oil phase. A water-oil emulsion is obtained by emulsifying the oil in an aqueous solution of diethanolamide fatty acids 2.

Однако при использовании этого состава происходит обводнение скважин за короткий срок из-за недостаточ-However, when using this composition, wells are flooded over a short period due to insufficient

Простым эмульгированием можно получать водонефт ные эмульсии при использовании в качестве дисперсной среды только жидких углеводородов.Water-oil emulsions can be obtained by simple emulsification by using only liquid hydrocarbons as a dispersed medium.

Цель изобретени  - улучшение изолирующих свойств состава дл  изол ции пластовых вод.The purpose of the invention is to improve the insulating properties of the composition for isolating formation water.

Указанна  цель достигаетс  тем, This goal is achieved by

Claims (2)

Формула изобретенияClaim 1 . Состав для изоляции притока пластовых вод в скважину, содержащий эмульгатор - водный раствор диэтаноламида жирных кислот с 10-16 углеродными атомами и дисперсную фазу, отличающийся тем, что, с целью улучшения изолирующих свойств состава, в качестве дисперсной фазы он содержит парафин при следующем соотношении компонентов, вес.%: Парафин 10-701 . Composition for isolating the influx of formation water into the well containing an emulsifier - an aqueous solution of fatty acid diethanolamide with 10-16 carbon atoms and a dispersed phase, characterized in that, in order to improve the insulating properties of the composition, it contains paraffin as the dispersed phase in the following ratio of components , wt.%: Paraffin 10-70 Водный раствор диэтаноламида жирных кислот с 10-16 углеродными атомами 30-90An aqueous solution of diethanolamide fatty acids with 10-16 carbon atoms 30-90 Диэтаноламины жирных кислот с 10-16 углеродными атомами 0,5-6Fatty acid diethanolamines with 10-16 carbon atoms 0.5-6 Вода ОстальноеWater Else 2. Способ по π. 1, отличающийся тем, что дисперсную фазу - парафин в расплавленном виде эмульгируют в нагретом выше температуры плавления парафина водном растворе эмульгатора с последующим естественным охлаждением полученной прямой эмульсии до отвердения дисперсной фазы.2. The method according to π. 1, characterized in that the dispersed phase - the paraffin in molten form is emulsified in an aqueous solution of an emulsifier heated above the melting point of paraffin, followed by natural cooling of the obtained direct emulsion until the dispersed phase solidifies.
