oil and gas production. SUBSTANCE: in a method of performing deep anode grounding including drilling borehole, placing metal conductor in borehole and filling borehole from bottom zone to head with conducting nonmetallic material, the latter is conducting cement mortar. Mortar is laid into hole by vertically displacing tube technique and metal conductor is positioned in non-hardened conducting cement mortar in head zone of hole. Injection tube or reinforcing steel bar can be used as metal conductor. EFFECT: increased lifetime of anode. 3 cl, 1 dwg |
