Zusammenfassung:	FIELD: well survey, particularly to investigate horizontal and directional wells. ^ SUBSTANCE: technological system comprises force transmission mechanism installed between transportation means and independent survey system. Force transmission mechanism is made as equal-arm double-arm lever with sliding units fastened to ends thereof and pivotally connected to rod. Limiting lever, balloon-type centralizer and joint unit, which connects the system with survey system, are serially installed on the rod. The limiting lever is pivotally connected with movable bush and with one sliding unit of double-arm lever. Another sliding unit of double-arm lever is secured to transportation means. ^ EFFECT: increased reliability of survey system movement inside well. ^ 5 cl, 1 dwg
