METHOD TO COMPLETE WELL WITH CARBONATE PRODUCTIVE RESERVOIR PENETRATED WITH RADIAL CHANNELS |
摘要 |
FIELD: oil and gas production industry, particularly development of wells having productive reservoir formed of carbonate basin and penetrated along with elongated radial channels creation. ^ SUBSTANCE: method involves performing interval cleaning of radial channels of water-oil emulsion by implosion method; moving the water-oil emulsion to ground surface; isolating reservoir zone to be treated from overlaying and underlaying well zones with packer; treating reservoir with the use of vibratory pulsator in acid composition medium beginning from lower reservoir zone; forcing acid composition in reservoir with water-free oil after reservoir permeability has been recovered; leaving well as it is for 5-6 hours to provide acid reaction with rock; causing reservoir product inflow by swabbing operation as reservoir zones are isolated one from another. ^ EFFECT: increased reservoir recovery due to complex well development. ^ 2 cl |
