Abstract
A long-rod milling shoe for milling a packer. The main problem of solving current milling shoe and milling the quality poor, milling speed is slow. The method is characterized in that: the internal thread is arranged in the upper end of the upper joint (1), the body (2) is connected with the lower end of the upper joint (1) through the thread, the difference between the upper joint (1) and the body (2) is positive, a step hole is axially arranged in the body (2), the lower end of the body (2) is provided with a hard alloy particle made into a tubular grinding head (3), the lower end of the grinding head (3) is provided with a water hole, and the lower end of the water hole is provided with an internal chamfer. The long-rod milling shoe for the milling packer has the characteristics of good milling quality and high milling speed.
Description
Technical field
This utility model relates to a kind of oilfield engineering field workover tool, especially milling packer stock junk mill.
Background technology
In oil well field, repair all kinds of casing damaged wells with junk mill.And existing junk mill is of poor quality owing to reasons in structure exists milling, the slow-footed problem of milling, and down hole problem or down-hole accident occur in mill inscription work progress, thus cause milling speed of application in down-hole slow, affect well workover efficiency.
Summary of the invention
Of poor quality in order to solve existing junk mill milling, the slow-footed problem of milling.This utility model provides a kind of milling packer stock junk mill.It is good that this milling packer stock junk mill has milling quality, the fireballing feature of milling.
The technical solution of the utility model is: this milling packer stock junk mill includes top connection and body.Having in top connection upper end under female thread, top connection and be threaded connection body, top connection is positive number with the difference of body, and the most internal axially have step hole, and body lower end has hard alloy particle to make tubulose bistrique, and bistrique lower end has hydrophthalmia, hydrophthalmia lower end to have interior chamfering.
This utility model has the advantages that this milling packer stock junk mill is owing to having female thread in using top connection upper end, it has been threaded connection body under top connection, top connection is positive number with the difference of body, the most internal axially have step hole, body lower end has hard alloy particle to make tubulose bistrique, bistrique lower end has hydrophthalmia, hydrophthalmia lower end to have the structure of interior chamfering.Bistrique is utilized to realize improving milling quality and the purpose of milling speed.To have milling quality good for this milling packer stock junk mill thus, the fireballing feature of milling.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
1-top connection in figure, 2-body, 3-bistrique.
Detailed description of the invention:
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, this milling packer stock junk mill includes top connection 1 and body 2.Top connection 1 has female thread in upper end, top connection has been threaded connection body 21 time, top connection 1 is positive number with the difference of body 2, step hole is axially had in body 2, body 2 lower end has hard alloy particle to make tubulose bistrique 3, bistrique 3 lower end has hard-metal insert, bistrique 3 lower end to have hydrophthalmia, hydrophthalmia lower end to have interior chamfering.
This milling packer stock junk mill is activity broken well milling packer specific purpose tool; which overcome the conventional well milling inefficient shortcoming of packer tool milling; enter under having smoothly, protection sleeve pipe, milling be effective, efficiency high; owing to body 2 possesses sizes, therefore polytype packer can be implemented milling operation.This instrument milling sword tooth is made up of high strength wear resistant material, can realize efficient milling under low the pressure of the drill.
This milling packer stock junk mill top connection 1 is arranged at the upper end of body 2.Junk mill is partially attached to the lower end of body 2, and YG alloy is arranged at bottom junk mill.This milling packer stock junk mill have employed all-in-one-piece junk mill structure, this structure is provided with a hydrophthalmia, milling operation in the case of huge discharge can be realized, hard-metal insert is studded with bottom junk mill, only need G.I.H to visit packer location during well workover and add appropriate the pressure of the drill milling, junk mill just can carry out milling to packer, after impaired packer milling, reintroduce this instrument, under enter other fishing tool and just can complete big displacement activity broken well complexity fishing junk repair, this milling packer stock junk mill simple in construction, easy to use, can be widely used among workover operation.
This milling packer stock junk mill is in south 1-60-water 11 well test application.This well packer, injection well downhole flow regulator are stuck, bury with sand, utilize Project Technical scheme, use survey stuck point, cut, salvage, sand washing, the mode such as set milling back-off complete oil pipe and salvage, for stuck packer salvaging aspect, under enter this milling packer stock junk mill, milling 0.5h completes, the high efficiency milling operation completing packer.Total data and test effect are normal.
This milling packer stock junk mill is in south 2-fourth 6-water 130 test application.This well packer, injection well downhole flow regulator are stuck, bury with sand, utilize Project Technical scheme, use survey stuck point, cut, salvage, sand washing, the mode such as set milling back-off complete oil pipe and salvage, for stuck packer salvaging aspect, under enter this milling packer stock junk mill, milling 0.4h completes, the high efficiency milling operation completing packer.
