Key words: flooding, perforation, cumulative projectile, well, horizon.
Secondary opening of productive oil and gas reservoirs using cumulative and bullet perforation methods in sloping wells with high values of zenith angles (40-60°) require the solution of a number of technological problems caused by the justification of the interval of their implementation. This is especially important for multi-layered reservoirs with alternating water and oil saturated horizons and the absence, as a rule, of an insulating low-permeability screen, for example, a clay layer (tire), ie, between water-bearing and oil-bearing strata there is only water-oil contact. The article makes an attempt to attract geological services, owners of companies that develop deposits with such conditions, in order to increase the requirements for the appointment of a perforation interval, given some proposals based on the actual results of well construction.
