发明名称 LOGGING SYSTEM FOR USE IN WELL UNDER SUBMERSIBLE ELECTRIC-CENTRIFUGAL PUMP
摘要 FIELD: oil and gas industry.SUBSTANCE: device comprises submersible electric-centrifugal pump and eccentric stabiliser and a nozzle with flowing channels for fluid passage are mounted on it, a cable, the upper and lower connecting elements with spring stops having contact with the cable and automatic gripper with gripping mechanism. At that the run in automatic gripper ensures connection or disconnection of the upper and lower connecting elements. The invention also suggests the logging method in the zone under submersible electric-centrifugal pump, which comprises in the well submersible electric-centrifugal pump unit assembled with the nozzle with flowing channels for fluid passage, eccentric stabiliser, the upper and lower connecting elements in position of mechanical and electrical contact, the cable, automatic gripper, weighting material and logging device at the cable downstream the submersible electric-centrifugal pump; start-up of the submersible electric-centrifugal pump in operating mode; disconnection of the upper and lower connecting elements by repeated one-time load of the automatic gripper mechanism; run out of the cable together with the logging device accompanied by measurements performed by the logging device in the well zone under the submersible electric-centrifugal pump.EFFECT: improved operational reliability of the submersible electric-centrifugal pump unit and potential periodic monitoring of the operated well without pump stop.13 cl, 3 dwg
