PROCEDURE FOR DEVELOPMENT OF MULTI-PAY OIL DEPOSIT

摘要

FIELD: oil and gas production. ^ SUBSTANCE: procedure for development of multi-pay oil deposit consists in casing string opening, in lowering packer on oil-well tubing (OWT), in positioning packer between reservoirs, in pumping hardening back-filling solution and in its conditioning. Back-filling solution is preliminary pumped and pressurised into a lower watered reservoir. Upon back-filling solution hardening in the reservoir the casing string is opened above the lower reservoir. Packer is set above interval of casing string perforation. A connecting rod receiving fluid from the watered reservoir by means of the pump is arranged at a lower end of the OWT string. ^ EFFECT: raised efficiency of procedure for development of multi-pay oil deposit due to maintaining operational mode of producer and elimination of filtration of reservoir water through annular space to upper payout reservoir of well thus increasing well operation period; reduced well production watering and increased reservoir recovery. ^ 1 dwg
