The collection kit of existing milling iron filings, the different magnetic force collection kit of structural shape normally, rely on subsidiary magnet absorption iron filings to collect, though iron filings that can the effective collection down-hole, but the deficiency on a lot of performances is arranged, be embodied in: 1. in the time need carrying out milling to the metal object of down-hole, at first milling tool is gone into the well and is carried out milling, after milling is finished, milling tool is lifted out well, and then change the magnetic force collection kit and go into the well the iron filings that produce are collected.Such course of work is the low cost height of going back of efficient not only.2. when using the magnetic force collection kit, magnet surface can weaken magnetic force after adsorbing a large amount of iron filings, causes adsorption capacity to descend, need repeatedly go into the well to collect and to remove clean down-hole iron filings, not only increase working strength of workers, also influenced job schedule, increased drilling cost.3. because magnetization effect is difficult to peel off the iron filings that are adsorbed on the magnet, the removing work of iron filings is spended time too.4. magnet price trend in the market is high, and the magnetic force collection kit belongs to running stores, will become the project that drilling cost increases.
Summary of the invention
The purpose of this utility model is, a kind of milling iron filings gatherer is provided.Can directly connect milling tool in its underpart and go into the well, can milling, collect disposable finishing, and collecting amount is big; Collect and simply to remove fast after iron filings go out well, can not pollute offshore boring island; Need not the magnet that uses price high; Alleviate working strength of workers, increase work efficiency and reduce drilling cost.
The technical solution of the utility model, a kind of milling iron filings gatherer of the present utility model comprises top connection, in the lower end of top connection by the valve body that has been threaded, in the lower end of valve body by the gathering-device that has been threaded, in the lower end of gathering-device by the lower contact that has been threaded.
In the aforementioned milling iron filings gatherer, described valve body comprises valve casing and the spool that is located in the valve casing, and valve casing top is threaded with top connection, and the cylindrical of valve casing bottom is threaded with gathering-device, and the endoporus of valve casing bottom is threaded with filter cylinder; The spool upper end is threaded with the valve cup.
In the aforementioned milling iron filings gatherer, described filter cylinder bottom lock, sidewall is evenly equipped with filter opening all around.
In the aforementioned milling iron filings gatherer, gapped between described spool and the valve casing, the middle part of spool and valve casing welding are provided with the anti-oral pore that recycles that connects spool and valve casing at weld, are provided with the anti-oral pore that is recycled on the valve casing below the weld.
In the aforementioned milling iron filings gatherer, described gathering-device comprises outer tube, is provided with tubular distance piece in the outer tube.
Compared with prior art, the utility model can directly connect milling tool and goes into the well in its underpart.Be equivalent to a drilling rod when normal probing, it can normal delivery moment of torsion and circulating drilling mud.When needs are collected iron filings, can milling, collect disposable finishing, and collecting amount is big; Collect and simply to remove fast after iron filings go out well, can not pollute offshore boring island; Need not the magnet that uses price high; Alleviate working strength of workers, increase work efficiency and reduced the use cost in oil field.The utility model is simple in structure, be easy to make, with low cost, safe and reliable, collect the iron filings amount big and get bits fast, environmental protection, simple, be convenient to operation, in use can reduce working strength of workers greatly, improve the operating efficiency in oil field.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.The utility model as shown in Figure 1.Comprise the top connection 1, valve body 2, gathering-device 3 and the lower contact 4 that are threaded successively.Described valve body 2 comprises valve casing 5 and is located at the interior spool 6 of valve casing that valve casing 5 tops are threaded with top connection 1 as shown in Figure 2, and the cylindrical of valve casing 5 bottoms is threaded with gathering-device 3, and the endoporus of valve casing 5 bottoms is threaded with filter cylinder 7; Filter cylinder 7 bottom locks, sidewall is evenly equipped with filter opening 9 all around.Spool 6 upper ends are threaded with valve cup 8.Gapped between described spool 6 and the valve casing 5, the middle part of spool 6 and valve casing 5 welding are provided with the anti-oral pore 10 that recycles that connects spool 6 and valve casing 5 at weld, are provided with the anti-oral pore 11 that is recycled on the valve casing below the weld 5.Gathering-device 3 comprises outer tube 12 as shown in Figure 3, is provided with tubular distance piece 13 in the outer tube 12.
Operating principle of the present utility model
As shown in Figure 1, the arrow among Fig. 1 is the reverse circulating circulating path of recirculated water.Gatherer of the present utility model is connected the milling tool rear end when work, when the down-hole metal object being carried out the milling operation, gatherer of the present utility model is equivalent to a drilling rod, the hole that recirculated water can pass through in the middle of the gatherer is from top to bottom washed the mud of drilling, and utilizes current that the mud in shaft bottom is brought out.At this moment, the utility model can normal delivery moment of torsion and circulating drilling mud and part iron filings.When needs are collected the iron filings of down-hole, only need drop into a steel ball 14 on drill string top, steel ball 14 falls by the hydrophthalmia of top drilling tool, and after steel ball 14 arrived valve cup of the present utility model 8 places, steel ball 18 was just blocked the hole in the middle of the valve cup 8, can't continue to fall.At this moment recirculated water can only be by gap between valve casing 5 and the spool 6 and anti-oral pore 11 stream that faces down outside gatherer of the present utility model that is recycled into, after arriving the shaft bottom, the recirculated water band the iron filings that milling gets off and is upwards flowed from the centre bore below, after being stopped by filter cylinder 7, fall into the feeder between gathering-device outer tube 12 and the tubular distance piece 13, finish collection work.
After finishing collection drilling tool is pulled out from the shaft bottom, only need unload lower contact 4 and just can smoothly iron filings be taken out; Unloading top connection 1 just can take out steel ball 14 smoothly; Lower contact 4 and top connection 1 just can continue to use from the new clothes.
