METHOD OF BOTTOMHOLE ZONE TREATMENT IN PRODUCTIVE RESERVOIR OF GAS WELL

摘要

FIELD: oil and gas industry.SUBSTANCE: method involves hydrophobisation of pore space in bottom-hole zone rock with 0.5-25% solution of polymethylhydridosiloxane in organic liquid containing its polymerisation catalyst. The solution is pushed down into the reservoir by gaseous agent selected out of nitrogen, natural gas, exhaust gases of combustion engines. Gaseous agent is fed to the well at a pressure exceeding reservoir pressure at least by 1.0 MPa. After the solution is pushed down, the well is left for process aging for two days.EFFECT: reduced water saturation of reservoir bottom-hole zone, enhanced gas well deliverability with single treatment of reservoir.3 tbl
