FIELD: mining; machine building.
SUBSTANCE: invention relates to wellhead system of geophysical cable suspension rollers at survey of wells with inclined mouth. System consists of two rollers. Rollers are installed on the frame in the form of a volume-frame structure by the ends of the axes protruding from the side cheeks of the rollers by means of nuts. Nuts are attached to the frame, and their screws are made with end elements covering the ends of roller axes. On the cheeks of one roller the geophysical cable guiding unit is attached. On the cheeks of the second roller there is an additional roller of the geophysical cable damper. Frame is pivotally mounted on the sledge and fixed with support-adjustable bolts. Frame also has a unit of additional attachment to the well casing and to the lubricator.
EFFECT: creation of a device guiding a geophysical cable coming from a logging hoist into a wellbore with an inclined mouth in a safe manner.
