FIELD: oil and gas industry.SUBSTANCE: device comprises surface equipment, which includes a ram bop, a sealing head, a lubricator with a receiving chamber and a rotary bracket and well equipment comprising a geophysical cable and well rigging. Well rigging comprises a logging device and joining units that act as a propeller and an extender. Electric connection between the logging device and surface equipment is carried out via the geophysical cable and slots. Delivery of the logging device into the survey interval is carried out by well rigging gravity. Well rigging and the geophysical cable are lowered into the well and withdrawn from the well in stages using a quick-detachable receiving chamber of a lubricator and a ram bop. The wellhead is sealed on adapters of joining units.EFFECT: simplified design, higher reliability, safety.2 dwg |
