Abstract
The utility model relates to a downhole litter grinding tool, especially to a dredging cup type grind shoe, comprises a head body and a grind shoe. The grind shoe is connected with the dredging cup which is arranged on the upper side of the joint body by screw button. The device can better make the iron fragments which are formed by the grind shoe grinding the downhole litter combine with the grind shoe organically, and all the fragments are put into the dredging cup, thus drilling wall sticking serious accident which is caused by incomplete litter cleaning is prevented from occurring. The utility model can be extensively used for reforming the existing grind shoe tool due to the simple structure and convenient using.
Description
Technical field:
The utility model relates to the trouble of lost tool in hole milling tool, particularly a kind of fishing cup formula junk mill.
Background technology:
Along with the development gradually of petroleum exploration and development, the various technology of drilling well are brought in constant renewal in, and bit speed has also been obtained the progress of advancing by leaps and bounds, but constantly can run into some stubborn problems in the drilling well, and such as the hand-held tool well that falls, drill bit falls tooth.Run into these problems in case drop, not only having a strong impact on rate of penetration or cause can't drilling well, and also can cause pernicious down-hole accidents such as bit freezing when more serious.Handle in the trouble of lost tool in hole accident in the existing technology and will handle, and be divided into for two steps, be lowered to junk mill in the well earlier and carry out milling with junk mill, with in the well greatly junk wear into fritter, be lowered to fishing cup again it salvaged well.Perhaps fishing cup and junk mill are connected on one, but the fishing cup cup is far away from bottom hole spacing, be unfavorable for salvaging, and the salvaging effect is relatively poor.In order to handle this type of down-hole accident fast and effectively, the better needs that adapt to this type of working environment, according to the duty under the adverse circumstances of down-hole with improve cutting power, improve the effect of handling, for this reason the fishing cup formula junk mill that provides for effectively dealing with problems just of the utility model.
The utility model content:
The utility model purpose is in order to overcome above-mentioned shortcoming, and the fishing cup formula junk mill that provides, and can realize that milling once finishes with salvaging junk, shortens the accident treatment time effectively.
Technical scheme:
For reaching above-mentioned purpose, the utility model comprises fittings body, junk mill composition, and described junk mill is connected by the fishing cup of screw thread with the fittings body top.
Between junk mill and fishing cup, the inclined to one side buttress thread by to each other is connected to each other, and is close together.
The utility model is by transferring drilling tool, with tool joint body and fishing cup, the tubing string G.I.H that junk mill is formed together grinds the position in advance, is ground a large amount of fragments of broken workpiece, because distance is very short between junk mill and the fishing cup, and it is not baffled between junk mill and fishing cup, iron block just can directly fall in the fishing socket, has promptly realized wearing away and has salvaged junk and once clear up, and is convenient especially during cleaning, shortened the accident processing time effectively, can make the interior causality loss of well drop to minimum point.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure by fittings body 1,, 2, axle, 3, fishing cup, 4, junk mill, 5, carbide alloy forms.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
Among the figure, fittings body 1 is to be positioned at the axle 2 left end heads that have inner duct, this joint endoporus is that bullet has the taper box, fishing cup 3 is equipped with in top, right part position at it, can be used to store polished metal junk fragment in the circular groove in the fishing cup 3 ring dress, and outside diameter is with to grind oblique external diameter identical, on the step of the right-hand member bottom surface of fishing cup, be provided with pin thread, the bottom of junk mill 4 is provided with carbide alloy 5, and there is hydrophthalmia at the junk mill center, is used for circulating mud to play to guarantee to creep into and grind that everything goes well with your work acts on.This hydrophthalmia communicates with the axle inner duct, and junk mill 4 and fishing cup axle 2 link together by terraced partially box and pin each other.
