FIELD: mining.
SUBSTANCE: method includes lowering of a downhole tool on a logging cable into a well shaft, fixation of the downhole tool in the well shaft at the first place of works in the well shaft, performing of an operation of sampling or taking specimens of beds of fluid medium using a sampling tool connected with the first section. At the same time the operation of sampling or taking specimens is performed at the second place of works in the well shaft, when the downhole tool remains fixed in the well shaft at the first place of works, and at the same time the second place of works is spaced with the first place of works in direction parallel to the longitudinal axis of the downhole tool. The first section of the downhole tool and the second section of the downhole tool are moved so that the first section of the downhole element is moved from the second place of works in direction parallel to the longitudinal axis of the downhole tool, and the second section of the downhole tool is moved to the second place of works in a direction parallel to the longitudinal axis of the downhole tool. Then the operation of core sampling is performed at the second place of works using a core sampling tool connected with the second section.
EFFECT: invention provides for more accurate performance of testing operations, operations of sampling or taking specimens, completion operations.
