Practical Experience in Applying the Technology of Creating a Networkof Deep-Penetrating Filtration Channels with the Intensification of theInflow in the Producing Wells of the Republic Unitary Enterprise ProductionAssociation Belorusneft

摘要

The staff of Belorusneft constantly invents,tests and adopts new technologies to develop hard-to-recoveroil reserves in the fields of the Pripyat Trough.Conventional reserves are under fast-paced development inthis region,while hard-to-recover reserves are not actively developed,although amounting up to 70% oftotal recoverable petroleum reserves.When targeted penetration of low-permeable intervals and creation ofa system of branched deep drainage channels are required,we developed equipment and technology thatallow creating a network of deep-penetrating flow channels.The channels run radially in relation to thewellbore with penetration depth of up to 100 m,which can significantly increase the formation fluid flowarea toward the wellbore.
