In operation of chinks during a filtration of layers containing active oil formation amyls in bottom to a zone is confirmed. Influence not newtonian properties amyls, formed in bottom to a zone on productivity of chinks has been studied. For the purpose of destruction amyls for normalization of a filtration of oil from a layer in a chink the reagent has been prepared and the technology is developed.
Researches have shown that the increase in a quantity of water in structure amyls leads to increase in structural viscosity and limiting pressure of shift, and at its presence more than 70% occur, inversion of phases.
Composition of containing 99,2-98,8% of an oil-alkaline withdrawal and 0,8-1,2% isomer spirit probably destruction amyls. The composition was introduced in the wells of OGPD “Balakhanineft” which resulted in additional production of 474 t. oil.
