FIELD: oil and gas extractive industry.
SUBSTANCE: device has pusher in form of stringed onto logging cable and fixed there cylindrical elements, providing rigidity to cable and load, fixed at cable above the pusher and generating necessary force for pushing equipment along steeply slanted shaft, where lowering of equipment on cable under their weight is difficult due to friction against well wall. Device has additional lower load fixed at cable below the pusher, and pusher is made with length for not less than 20-25% greater than length of the longest steeply slanted well portion, where lowering of equipment on cable under their weight is difficult due to friction against well wall.
EFFECT: higher efficiency.
