FIELD: oil-well drilling. SUBSTANCE: drilling out deposits according to design well grid, geophysical, hydrodynamic, and laboratory investigations, hydrocarbon sampling in mode of depleted stratum energy, followed by pumping displacing agent in zones of poor penetrability. Pumping displacing agent in is carried out on decreasing stratum pressure by a value of initial oil displacement between zones of extraction and water bearing area. Wells with the highest rate of stratum pressure drop and the least hydroconductivity are developed for pumping displacing agent in. As stratum pressure is recovered over the deposit, additional wells with the least rate of stratum pressure recovery and the least hydroconductivity are developed for pumping displacing agent in. EFFECT: highly efficient development of wells. 2 dwg
