ABSTRACT
At present, the share of hard-to-recover reserves in Russia and in the world is growing. Production on the many wells are stopped, due to the lack of flow of formation fluid, or due to the high water content of the production. The unprofitability of oil production at wells with hard-to-recover reserves leads to their conservation or liquidation. In this article, we offer an innovation Perfobur system. It is modern technology of non-damaging perforation for increase of the flow rate of producers, enhancement of the injection capacity of injectors and elimination of cones of water-gas-oil contacts due to expansion of the filtration area. In the article the questions of advantages of drilling of small-diameter channels, capabilities and technical efficient of Perfobur systems are studied.
