PROCEDURE FOR RESTRAINT OF WATER PRODUCTION IN WELL

摘要

FIELD: oil and gas production. ^ SUBSTANCE: procedure for restraint of water production in well consists in pumping solution of CL (cultural liquid) into insulated interval. Two equal portions are pumped. The first portion corresponds to solution of CL prepared on soft water of 1000 kg/m3 density at ratio 1:0.5-1, while the second one corresponds to solution prepared on reservoir mineralised water of density up to 1190 kg/m3 at ratio 1:0.3-0.5. ^ EFFECT: raised efficiency of repair-insulation operations due to creation of more resistant to water outbreak screen of water solutions of silicon-organic liquid - CL with controlled period of gelation excluding their preliminary hardening. ^ 3 tbl
