FIELD: oil and gas production.
SUBSTANCE: method for well conductivity improvement between proppant supports is characterised by treating a free crack face or crack space between the supports with a chemical reagent with the use of a blocking mask generated by substances recovered from said supports, and the chemical reagent is squeezed with pressure lower than breakdown pressure to be flushed with using an injection liquid for control rock wettability and to dissolve natural clays and deposits.
EFFECT: higher well yield.
