Description

Magnet salvages post and strong magnetic die
Technical field
Cleaning drilling technology field is the utility model is related to, is that a kind of magnet salvages post and strong magnetic die.
Background technology
With the extensive use of directional well, horizontal well and old well reparation in oil field development, to milling trouble of lost tool in hole, windowing Or when repairing well inner tube string, irony chip that milling an is fallen part during upper return, which can often accumulate, agglomerating causes moment of torsion to increase Greatly, or even bit freezing can be caused;A part for sinking causes the milling repeated again, causes milling efficiency low, can also cause Milling tool early damage, extends the engineering time, increases cost allowance.
The content of the invention
The utility model provides a kind of magnet and salvages post and strong magnetic die, overcomes the deficiency of above-mentioned prior art, It can effectively solve the problems, such as the agglomerating moment of torsion increase of iron filings or even cause lock of tool drilling or sinking to cause to repeat milling.
One of the technical solution of the utility model is realized by following measures:A kind of magnet salvages post, including core Axle and magnet piece, circumferentially axially spaced-apart is provided with least three elongated slots on mandrel outer wall, and magnet piece is fixedly mounted in elongated slot.
The two of the technical solution of the utility model are realized by following measures:A kind of strong magnetic die, including magnetic Stable to drag for post, top connection and lower contact, top connection and magnet are salvaged post upper end and are fixed together, and lower contact and magnet are salvaged Post lower end is fixed together.
Here is the further optimization and/or improvements to above-mentioned technical proposal:
Above-mentioned magnet number of blocks is 42 pieces.
Circumferentially axially spaced-apart is uniformly provided with four elongated slots on above-mentioned mandrel outer wall.
The outer face of above-mentioned magnet piece and mandrel outer wall flush.
Above-mentioned top connection lower end inside and magnet are salvaged to be together by a threaded connection on the outside of post upper end.
Salvage post lower end outside with magnet on the inside of above-mentioned lower contact upper end and be together by a threaded connection.
The utility model reasonable and compact in structure, it is easy to use, by the utility model be fixedly connected on drill bit, junk mill or Milling shoe upper end, during milling is carried out, post is salvaged in magnet by the strong suction absorption of magnet when iron filings on drilling fluid by returning In intermediate annular elongated slot, avoid iron filings and sink to causing to repeat milling, or on accumulate when returning agglomerating, accelerate milling speed, Reduce milling risk.
Brief description of the drawings
Accompanying drawing 1 is the main view cross section structure diagram of the utility model embodiment 2.
Coding in accompanying drawing is respectively:1 is mandrel, and 2 be magnet piece, and 3 be elongated slot, and 4 be top connection, and 5 be lower contact.
Embodiment
The utility model is not limited by following embodiments, can according to the technical solution of the utility model and actual conditions come Determine specific embodiment.
In the utility model, for the ease of description, the description of the relative position relation of each part is according to specification The Butut mode of accompanying drawing is described, such as:The position relationship of upper and lower, left and right etc. is the Butut side according to Figure of description Always determine.
The utility model is further described with reference to embodiment and accompanying drawing:
Embodiment 1:As shown in Figure 1, the magnet, which salvages post, includes mandrel 1 and magnet piece 2, along circle on the outer wall of mandrel 1 All axially spaced-aparts are provided with least three elongated slots 3, and magnet piece 2 is fixedly mounted in elongated slot 3.So can be by being installed on mandrel 1 Magnet piece 2 adsorbs iron filings.
Post can be salvaged to above-mentioned magnet and made further optimization and/or improvements according to being actually needed:
As shown in Figure 1, the quantity of magnet piece 2 is 42 pieces.So, magnet piece 2 is that Rare-Earth Magnetic iron block can preferably adsorb iron Bits, magnet piece 2 are inlaid on mandrel 1 in pairs..
As shown in Figure 1, circumferentially axially spaced-apart is uniformly provided with four elongated slots 3 on the outer wall of mandrel 1.So, it is symmetrical Iron filings are preferably adsorbed in cylindrical mandrel 1.
As shown in Figure 1, the outer face of magnet piece 2 and the outer wall flush of mandrel 1.So, the diameter of mandrel 1 and magnet piece 2 Diameter is identical, and post intermediate annular elongated slot 3 is salvaged in magnet by the strong suction absorption of rare-earth magnet when iron filings on drilling fluid by returning In.
Embodiment 2:As shown in Figure 1, the strong magnetic die includes magnet salvaging post, top connection 4 and lower contact 5, above connects First 4 lower end inside and magnet are salvaged to be fixed together on the outside of post upper end, and on the inside of the upper end of lower contact 5 and magnet salvages post lower end Outside is fixed together.So, magnet salvages outer surface of the post less than top connection 4 and lower contact 5, and it is long to form an annular Groove 3, in order to adsorb more iron filings.
Above-mentioned strong magnetic die can be made further optimization and/or improvements according to being actually needed:
As shown in Figure 1, the lower end inside of top connection 4 and magnet are salvaged is together by a threaded connection on the outside of post upper end.This Sample, it is easily installed dismounting.
As shown in Figure 1, salvage post lower end outside with magnet on the inside of the upper end of lower contact 5 and be together by a threaded connection.This Sample, installing/dismounting during convenient use.
Above technical characteristic constitutes embodiment of the present utility model, and it has stronger adaptability and implementation result, can According to the non-essential technical characteristic of increase and decrease is actually needed, to meet the needs of different situations.
