Beschreibung
Zusammenfassung:	FIELD: oil and gas industry, particularly devices for well survey and oil or gas sample taking. ^ SUBSTANCE: method involves lifting lubricator; inclining lubricator through 40-45° to vertical line and retaining thereof in inclined position during bottomhole apparatus insertion; lowering lubricator in well and vertically installing thereof on connection unit of well production tree. The simultaneous lifting, inclination, retaining, as well as simultaneous lowering and installation operations are carried out with the use of mechanism. The mechanism comprises two cantilever arms connected one to another by worm gear type screw adapted to bring together and pull apart above arms under handle rotation. ^ EFFECT: extended possibilities of well survey in difficult-to-access areas characterized by severe climate and geographical environment without the use of hoisting equipment, increased efficiency or work performance due to reduced costs and decreased time of technological operation performing. ^ 2 dwg
