METHOD FOR COMMISSIONING productive reservoirs in wells at later stages of development

摘要

Input method for use productive formations in a late stage of development wells containing tailing-boring perforations and creating drawdown, characterized in that during the opening of seams drill perforator with an increased yield of the drill into the rock monitor the passage of a drill through metal casing column cement stone and rock largest recorded load on the drive mechanism extension drill, thus increasing the process load register on the drive mechanism extension drill during its passage zakolmatirovannoy zone deeper rock least 250-300 mm and the moment of abrupt reduction of said load after passing zakolmatirovannoy rock zone immediately after registering which produce pressure drop in the casing below the hydrostatic level of not less than 0, 5 MPa.
