Abstract

1. Способ повышения проводимости трещины в пространстве между опорами проппанта, характеризуемый обработкой свободной поверхности трещины или пространства трещины между опорами химическим реагентом с использованием защитной маски, образуемой веществами, выделившимися из указанных опор. ! 2. Способ по п.1, отличающийся тем, что химический реагент закачивают в скважину после образования проппантных опор. ! 3. Способ по п.1, отличающийся тем, что химический реагент закачивают в скважину одновременно с частицами проппанта в виде твердых частиц, способных генерировать химический реагент под действием условий скважины. ! 4. Способ по п.1, отличающийся тем, что в качестве веществ, образующих защитную маску, используют смолистые покрытия частиц, способные растворяться в условиях скважины. ! 5. Способ по п.1, отличающийся тем, что в качестве веществ, образующих защитную маску, используют смолистые вещества, скрепляющие частицы проппанта в опоры.1. A method of increasing the conductivity of a crack in the space between proppant supports, characterized by treating the free surface of the crack or the crack space between the supports with a chemical reagent using a protective mask formed by substances released from these supports. ! 2. The method according to claim 1, characterized in that the chemical reagent is pumped into the well after the formation of proppant supports. ! 3. The method according to claim 1, characterized in that the chemical reagent is pumped into the well simultaneously with proppant particles in the form of solid particles capable of generating a chemical reagent under the action of the well conditions. ! 4. The method according to claim 1, characterized in that as the substances forming the protective mask, resinous coatings of particles capable of dissolving in well conditions are used. ! 5. The method according to claim 1, characterized in that as the substances forming the protective mask, resinous substances are used that fasten the proppant particles into supports.
