LUBRICATOR for research of oil and gas wells

摘要

The invention relates to the oil and gas industry, namely to devices providing geophysical and hydro research and operations in oil and gas wells geophysical instruments and instruments on the flexible member. The technical result is to create a design, which has the structural simplicity and to improve the ease of assembly, disassembly and maintenance of the lubricator. The lubricator consists of a connecting flange 1, the receiving chamber, the seal assembly of the flexible member 3 and the guide rollers 4 and 5 mounted on the upper 6 and lower pivot bracket 7. The bracket 6, the upper roller 4 is mounted directly on top of the reception chamber 2 and is provided with additional fixed rack 8 with the possibility of quick connection to the bracket and a rotatable bush through-spindle connection 9. The lower roller 5 is adapted to releasable connection to the lower arm 7 ohm easily removable by the axis 10 and the retainer 11 which are provided with harnesses linked to the bracket 7. The cheeks 13 of the lower bracket 7 mounted on the roller 5 half sleeve 14, with the possibility its releasable connection to the housing of the receiving chamber 2 by the cap nut 15 mounted on the housing of the receiving chamber and having an inner annular groove 16 corresponding to the size of the upper end of the half sleeve 14 and by a further annular groove 17 corresponding to the size of the lower end half sleeve 14 and formed in the acceding Yelnia nipple adapter element 18 Compound 19 housing receiving chamber 2 with the adapter 20.
