Abstract
A multifunctional fish top dresser relates to a fish top dresser. The utility model solves the problem in the prior art that the fish dressing effect cannot be reached and the complete fish dressing purpose cannot be realized because a bushing can be scraped by the lower end of a tool, the friction between the tool body and the bushing is great, the bushing can be damaged when the toll is rotating and the mill liner is unstable as well as the eccentric friction is easily happened. A ball bearing (5) of the utility model is inlaid on the surface of the excircle of a lower body (2-2). Mill liner blade teeth (3) are composed of external mill liner blade teeth (3-1) and internal mill liner blade teeth (3-2). A bottom surface (2-3) of the lower body (2-2) consists of a concave surface (2-4) and a plane (2-5). The raised internal mill liner blade teeth (3-2) are evenly distributed along the circumference of the concave surface (2-4), and the external mill liner blade teeth (3-1) are evenly arranged along the circumference of the plane (2-5). In addition, an external chamfer angles C and an internal chamfer angles B of the external mill liner blade teeth (3-1) are in 45 degrees. Being tested for a plurality of times, the utility model is proved to have preferred using effect, 100% of successful ratio for fish dressing, therefore, the construction requirement of the releasing fishing can be completely met.
Description
Technical field
The utility model relates to a kind of top of fish trimmer.
Background technology
Flat or the concave bottom junk mill that on conventional straight well, is used to repair a fish operation for big gradient section of horizontal well and horizontal segment to repair the fish operation inapplicable, mainly there is following technical problem: the one, its lower end meeting scratching sleeve pipe during the instrument lower going-into-well, instrument is hampered, and is lowered to difficulty; The 2nd, instrument is close to the sleeve pipe lower wall, and tool body and sleeve friction are big, increases the frictional force when rotating, and sleeve pipe is caused damage; The 3rd, instrument milling sword tooth directly contacts with sleeve pipe, damages sleeve pipe when instrument rotates; The 4th, because the fish head is close to the casing wall downside, the milling instability, easily eccentric wear does not reach and repaiies the fish effect; The 5th, there is the milling blind area for being close to sleeve pipe lower wall part junk, can't realize the complete fish eyes of repairing.
The utility model content
The utility model provides a kind of multi-functional top of fish trimmer, to solve the following technical problem that exists in the reality technology: the one, its lower end meeting scratching sleeve pipe during the instrument lower going-into-well, instrument is hampered, and is lowered to difficulty; The 2nd, instrument is close to the sleeve pipe lower wall, and tool body and sleeve friction are big, increases the frictional force when rotating, and sleeve pipe is caused damage; The 3rd, instrument milling sword tooth directly contacts with sleeve pipe, damages sleeve pipe when instrument rotates; The 4th, because the fish head is close to the casing wall downside, the milling instability, easily eccentric wear does not reach and repaiies the fish effect; The 5th, there is the milling blind area for being close to sleeve pipe lower wall part junk, can't realize the complete fish eyes of repairing.The utility model is made up of top connection 1, body 2, milling sword tooth 3, hydrophthalmia 4 and ball 5, and body 2 is made up of upper body 2-1 that makes one and lower body 2-2, and the diameter of upper body 2-1 is less than the diameter of lower body 2-2, and the top of upper body 2-1 is connected with top connection 1; Ball 5 is embedded on the outer round surface of lower body 2-2, milling sword tooth 3 is made up of outer milling sword tooth 3-1 and interior milling sword tooth 3-2, the bottom surface 2-3 of lower body 2-2 is made up of concave surface 2-4 and plane 2-5, concave surface 2-4 is provided with hydrophthalmia 4, the interior milling sword tooth 3-2 that circumferentially is evenly equipped with projection along concave surface 2-4, the end of interior milling sword tooth 3-2 be fixed in concave surface 2-4 in the heart, the other end of interior milling sword tooth 3-2 is fixed on the outward flange of concave surface 2-4, milling sword tooth 3-1 outside circumferentially being evenly equipped with of plane 2-5, the end of outer milling sword tooth 3-1 is fixed on the outward flange of concave surface 2-4, the other end of outer milling sword tooth 3-1 is fixed on the outward flange of plane 2-5, and the outer chamfering C of outer milling sword tooth 3-1 and interior chamfering B are 45 °.
The utlity model has following beneficial effect: the inside and outside chamfering in outer milling sword tooth rim of the present utility model limit is respectively 45 ° of chamferings; outer chamfering prevents down fashionable scratching sleeve pipe, milling sleeve pipe when repairing fish; play the effect that prevents sidetracking, protective casing; interior chamfering has the effect of receiving fish; interior milling sword tooth through outside milling sword tooth tentatively repair after and the further milling of fish head that is introduced into is repaired, until rule; satisfy the requirement of salvaging; on body, used ball, have set upright, the effect of abrasionproof, drag reduction.Simultaneously, milling sword tooth adopts novel milling material, has improved and has repaiied fish efficient.
