Abstract

FIELD: mining, explosion in oil wells. SUBSTANCE: string 2 of pump- compressor pipes is lowered into the well with jet pump 4 and packer 5. Interpipe space is sealed. Sealing unit 6 is installed on geophysical cable 9. Perforator 1 is secured to cable end. Perforator 1 is lowered together with sealing unit 6 through string 2 until sealing unit is allocated in through passage 4 of jet pump 4 and perforator 1 in perforation interval 3. Preset depression is created in under packer zone by keeping working liquid swinging slightly through jet pump 4. Stratum fluid is fed in well using cyclic depressions applied to the stratum. Once all perforation interval has been filled with fluid, perforator 1 is withdrawn together with sealing unit 6 from the well. Perforator 1 equipped once again is lowered into the well with sealing unit. Once depression has been created perforator 1 is shot off once again. Then perforation passages are cleaned up immediately by applying cyclic depression to the stratum. Perforator 1 is withdrawn from the well together with jet pump 4, and the well is brought into operation. EFFECT: high productivity. 1 dwg
