FIELD: well drilling technology.
SUBSTANCE: device has drilling equipment lowered into the well: chisel, face engine, drilling pipes with protective container with geophysical equipment placed in lower drilling pipe. Geophysical device has cable(wired) communication line to surface, made of following interconnected parts: dropped cable section, expandable drilling pipes and leading drilling pipe with in-built cable sections and swivel with current receiver. Geophysical device and dropped cable section are made with possible lowering and delivery of geophysical device into protective container located in horizontal shaft, on dropped cable section, under force from flow of washing fluid.
EFFECT: less time spent on hoisting operations.
