Description
Technical field
This utility model relates to underground operation tool, particularly relates to a kind of New Kind of Anti-Abrasion type stile.
Background technology
Centralizer is that drill string during high speed revolution, keeps elongate drill rod steadily to operate, makes drill axis as far as possible in hole
Close to a kind of utensil of drill center line, the when of using centralizer in actual underground work, due to the existence of dog-leg, cause
Drilling rod and sleeve pipe produce vibrations and friction, cause sleeve pipe and drill rod abrasion serious, and casing wear the most then reduces sleeve pipe tubing string
Anti-collapse, internal pressure strength, have a strong impact on the safety of the mining operations of drilling well subsequently, completion and follow-up oil gas, heavy then
Causing casing collapse, deform, leak, even full well is scrapped, and drill rod abrasion also results in quickening drilling rod and lost efficacy, and service life is in advance
Shorten, seriously can cause drill rod breaking, cause serious down-hole accident.Chinese utility model patent CN203702024U discloses
A kind of novel rotatable drill pipe centralizer, including fin, centralizer main body, roller bearing, shielding plate, male thread and box thread, righting
Device main body and fin are an overall structure, arrange three fins, and centralizer main body circumferentially-spaced 120 ° of centralizer main body
One end is provided with male thread, and the other end is provided with box thread, and fin is a segment structure, and lug center is provided with a semicylinder
Groove one, is respectively arranged with a scalloped recess at semicylinder groove one two ends, is placed in the groove of fin by roller bearing, and fans at fin
Shielding plate is installed on connected in star, is fixed by bolt.The friction that contacts between sleeve pipe with drilling rod can be turned by this centralizer
Turn to rolling friction, greatly reduce the friction between drilling rod and sleeve pipe, be effectively protected sleeve pipe and drilling rod, but still suffer from
Lower deficiency: first, by by the way of arranging roller bearing in groove, only decreases the friction of centralizer direction of rotation, but
Axial friction can not be reduced, actual lower beam when, drilling rod still has axial abrasion and exists；Second, in righting
Device main body arranges fin and centralizer main body and fin is the structure of integral type, can make centralizer make when operation more
Complexity, increases manufacture difficulty, cost and time；3rd, the when of using centralizer in actual underground work, due to dog-leg
Existing, except making drilling rod friction sleeve pipe, also can produce vibrations, this centralizer only has the merit of the friction reducing rotation direction
Can, and without shock-absorbing function.
