Abstract
The utility model relates to a drilling and milling type fishing tap which is used in oil and water well repairing operation fishing construction and is composed of a joint, a water eye, a tap body, buckle producing screw thread and a milling head, wherein an inner screw thread joint is arranged on the upper portion of the tap body, the buckle producing screw thread is arranged on the ex-circle surface on the lower portion, the water eye is arranged in the center, and the milling head is welded on the lower end. The drilling and milling type fishing tap of the utility model has novel structure, the fishing function and the drilling and milling function. The drilling and milling type fishing tap is utilized to drill and mill hard objects and can smoothly finish well repairing operations for fishing underground junks, which is beneficial for simplifying well repairing procedures and shortening the well repairing constructing time.
Description
Technical field:
The utility model relates to a kind of downhole tool that is used for oil, well workover treatment salvaging construction, belongs to petroleum well workover power tool class.
Background technology:
Along with the prolongation of oil field development with oil, well production time, the frequency and the well of generation trouble of lost tool in hole fault get more and more, and serve as that main workover treatment work amount of constructing content increases day by day with the salvaging trouble of lost tool in hole.Die nipple is a special-purpose downhole tool of salvaging junk, and at present, normally used die nipple only possesses the function of salvaging and do not possess to bore and mill function in the petroleum well workover operation.And junk needs to carry out thread making with die nipple sometimes and salvages in the salvaging well, and its method is die nipple to be connected with drilling rod go into the well, make die nipple insert fish chamber (junk endoporus) and pressurize and rotate, and on the wall of fish chamber thread making, catch junk, it is pulled out.Yet, when the fish chamber is stopped up by hard thing, do not mill function because existing die nipple bores, thereby can not insert the fish chamber and can't salvage.
The utility model content:
Thereby the purpose of this utility model be to provide a kind of have to bore mill the brill that function can carry out oil, well trouble of lost tool in hole fishing smoothly and mill the formula fishing tap.
The utility model is to realize like this.This kind fishing tap is made up of die nipple main body, joint, hydrophthalmia, thread making screw thread and milling head, and die nipple body top is provided with female adapter, and the bottom periphery is provided with the thread making screw thread, and the center is provided with hydrophthalmia, the lower end welding or the milling head of having spliced.During work, end joint on this fishing tap is connected drilling rod lower end and G.I.H thereupon, if in the fish chamber foreign matter is arranged, by hydrophthalmia circulation workover fluid, pressurization rotation die nipple, milling head contacts with foreign matter it is ground, and workover fluid is taken away the foreign matter that grinds, and die nipple enters the fish chamber, under the effect of the pressure of the drill and moment of torsion, die nipple is thread making on the wall of fish chamber, catches junk that it is pulled out, finishes salvaging.
The utility model novel structure has salvaging and brill concurrently and mills function, utilizes it to bore and mills hard thing, finishes the workover treatment of salvaging trouble of lost tool in hole smoothly, helps simplifying workover operation, shortens the well workover engineering time.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of joint 1, hydrophthalmia 2, die nipple main body 3, thread making screw thread 4 and milling head 5, and its structure, assembled relation are as follows: die nipple body 3 tops are provided with female adapter 1, and the bottom periphery is provided with thread making screw thread 4, the center is provided with hydrophthalmia 2, and the lower end is welded with milling head 5.Wherein, joint 1 is made as one with die nipple main body 3, and its upper end is provided with the internal thread that matches with drilling rod lower end external screw thread.Thread making screw thread 4 has certain degree of hardness, can carry out thread making to steel goods such as oil pipes under the effect of power, and milling head 5 adopts the YD alloy to make, and is torus, takes electric welding welding or brazing to splice in die nipple main body 3 lower ends.
