Locking ring for casing centralizer

机译:套管扶正器锁环

摘要

The invention relates to oil industry, namely to the devices for fastening the tooling, in particular, centralizers, on a pipe string, run into the well with the zenith angle of more than 45 °. Retaining ring centralizer casing comprises a set having a triangular shape in cross section over the centering stop ring with internal grooves and a radial window for entering into grooves of the locking sided flat wedge, an inclined surface which is longitudinally formed locking ribs in the form of grooves and projections, with this ring width is satisfied not less than 30 mm, the inner groove is provided on both sides of the window shape and size of the locking wedge, and opposite of said KPA in the wall of the ring formed with threaded radial bore under the hollow locking bolt with internal hole for a hexagon wrench. Such constructive arrangement of the locking ring will provide further improved reliability to stragivayushim efforts centralizers or other snap-on descent into the well casing and hence prevent their displacement from the installation site, which ultimately lead to quality wellbore cementing. At the date of filing the locking ring is made at the factory. His field tests have yielded positive results. 1 PF 3 Fig.
