Abstract
The utility model is a kind of new V-neck V eye junk mill, is made of junk mill ontology, mainly includes female thread, inner hole, wing ontology, centralizer wing, hard alloy columnar, pin thread, alloy block composition；The ontology, which opens up, sets rectangular slot, and size is consistent with wing ontology, it is ensured that the weld strength of ontology and wing ontology, meanwhile, guarantee that wing ontology is uniformly distributed in circumferencial direction；Wing ontology lower end " L " type setting, so that tool can be cut with casing with quick and stable；The centralizer wing and ontology are integral type, are fallen off well risk to reduce centralizer wing.
Description
Technical field:
The utility model relates to a kind of neck eye junk mills of petroleum gas well workover, and more specifically, it relates to a kind of new
V-neck V eye junk mill.
Background technique
Under current oil environment, adjustment well becomes one of the major measure of stable yields volume increase.Since platform slot quantity has
Limit, is becoming tight drilling well-head day, and the inefficient old wellbore of low yield becomes the main target of adjustment sidetracking.Old well can be efficiently used
Eye, key factor are to meet drilling well and later period production needs, this just needs to take out shallow-layer casing, especially bilayer sleeve, difficulty
It does not have ripe experience greatly and both at home and abroad for using for reference very much.Therefore, each layer casing early period that old wellbore sidetrack wellbore prepares is handled
Cause more and more concerns.
Big wellbore sidetrack wellbore preparation work generally frequently with process such as cutting, set milling and millings, but covers milling and is making
It will appear backing pressure during industry, set splits casing, set leakage riser pipe and well head shake the problems such as violent；Meanwhile milling operation is imitated
Rate is very low；Especially when casing is not placed in the middle, set milling can be lower；Aiming at the problem that covering milling/milling low efficiency, design a kind of novel
Eye junk mill is led, operating efficiency is greatly improved, shortens adjustment well project duration, to achieve the purpose that cost efficiency.
Utility model content
The utility model is to solve technical problem present in well-known technique and provide a kind of new V-neck V eye junk mill, to solve
The problem of covering milling/milling low efficiency greatly improves operating efficiency, shortens adjustment well project duration, to reach cost efficiency
Purpose.
The utility model be solve well-known technique present in technical problem and the technical solution adopted is that:
A kind of new V-neck V eye junk mill, is made of junk mill ontology, and it is L-shaped that shown junk mill ontology, which is welded with bottom by slot,
Wing more than described slot at least two is axially equally spaced along junk mill ontology；Righting is connected on the junk mill ontology
The wing.
The wing side surfacing alloy block.
The alloy is block-shaped to be square, rectangle, pentagon and hexagon.
The centralizer wing surface inserting hard alloy columnar.
The wing bottom L have curved surface radian, 50 °~80 ° of radian size.
Beneficial effect
1. the utility model be integral type, mainly by female thread, inner hole, ontology, wing ontology, centralizer wing, hard alloy columnar,
On the body, the processing is simple for pin thread, weld seam, the welding of alloy block composition wing ontology, easy to maintenance, reduces production cost；This reality
The cutting of traditional handicraft is replaced into grinding with novel, greatly improves operating efficiency, shortens adjustment well project duration, to reach drop
The purpose of this synergy；
2. the utility model sets rectangular slot by opening up in ontology, size is consistent with wing ontology, it is ensured that ontology
With the weld strength of wing ontology；Meanwhile guaranteeing the weld strength of ontology and wing and making wing ontology equal in circumferencial direction
Cloth；
3. the utility model is arranged by wing ontology lower end " L " type, so that tool and casing can be with quick and stables
Cutting；
4. the utility model is versatile, wide adaptability.
Detailed description of the invention
Fig. 1 is a kind of new V-neck V eye junk mill structural schematic diagram of the utility model.
Fig. 2 is a kind of new V-neck V eye junk mill A-A sectional view of the utility model.
Fig. 3 is a kind of new V-neck V eye junk mill B-B sectional view of the utility model
Specific embodiment
In order to further appreciate that the contents, features and effects of the utility model, following instance is lifted, and cooperate attached drawing detailed
It is described as follows:
As shown in Fig.1 and Fig.2, the utility model provides a kind of new V-neck V eye junk mill, mainly by female thread 1, inner hole 2, ontology 3,
Wing ontology 4, centralizer wing 5, hard alloy columnar 6, pin thread 7, weld seam 8, alloy block 9 form；The female thread 1 and pin thread 7 are petroleum
With dedicated button, different button-types can be selected to meet different purposes according to customer requirement；The ontology 3, which opens up, sets rectangular slot 31,
The rectangular slot 31 is axially equally spaced along junk mill ontology 3, and size and wing ontology 4 are consistent, it is ensured that ontology 3 and wing
The weld strength of ontology 4, meanwhile, guarantee that wing ontology 4 is uniformly distributed in circumferencial direction；The wing ontology 4 welds on the body 3,
To reduce production cost；The setting of 4 lower end of wing ontology " L " type, the wing bottom L have curved surface radian, radian size
50 °~80；Cut tool can with quick and stable with casing；The 4 side surfacing alloy block 9 of wing ontology, is used for
Milling casing.
As shown in figure 3, the centralizer wing 5 is integral type with ontology 3, fall off well risk to reduce centralizer wing 5；Institute
5 surface inserting hard alloy columnar 6 of centralizer wing is stated, underground wearability is improved with it.During field operation, when casing is not placed in the middle
When, set milling/milling efficiency is very low, and new V-neck V eye junk mill replaces grinding with cutting, greatly improves operating efficiency, shortens adjustment well
Project duration, to achieve the purpose that cost efficiency.
The above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art
Under the enlightenment of the utility model, in the case where not departing from the utility model aims and claimed range, may be used also
To make many variations, these belong to the column of the protection of the utility model.
