Abstract
Integration tool is salvaged in the milling drifting of a kind of set, including drift size gauge tool, fishing tool, top connection, screw thread, set milling head, described drift size gauge tool one end has import, and import is horn-like, and there is squint face at described import two ends, and described squint face and top connection are 45 jiaos；Described top connection and drift size gauge tool screwed connection, and described top connection passes through import and is connected with fishing tool, described top connection and fishing tool pass through screwed connection；The described drift size gauge tool other end is equipped with set milling head；Drifting milling being salvaged and being ideally combined together, one flow chart just completes above operation well, shortens more than 60% duty cycle, and operating cost also can save more than 60%.
Description
Technical field
The utility model relates to underground work field, is specifically related to the milling drifting of a kind of set and salvages integration tool.
Background technology
It during well workover, is frequently encountered some small falling object and causes construction to be obstructed, it is necessary to after salvaging or milling
Junk is taken out of ground by circulation workover fluid, and traditional process technique typically uses junk mill milling broken or with conventional tool of tackling all problems at once
Salvage, but due to himself structure and use operation restriction, it may appear that even invalid the showing of the poor efficiency repeatedly salvaged
As increasing labour intensity, adding operating cost.The patent No. 02255499.8 discloses a kind of overshot for underground job, it
Being made up of top connection and seating nipple etc., the bottom of seating nipple can connect guide shoe or directly design guide shoe, and top connection joins with seating nipple
Connecing, circle slips is arranged in seating nipple, is connected fixing by screw.The utility model external diameter is little, preventing covering upside down, can exit, operation letter
Single.Using in salt crust, the oil-water well of fouling and casing deformation well, scraping action is little, easily under enter, developing result is good, but by
Complex in well, it is undesirable that it salvages small falling object effect.
Utility model content
For solving the deficiencies in the prior art, the utility model provides one set milling drifting to salvage integration tool.
The technical solution of the utility model is: integration tool is salvaged in the milling drifting of a kind of set, including drift size gauge tool, fishing tool,
Top connection, screw thread, set milling head, described drift size gauge tool one end has import, and import is horn-like, and described import two ends have tiltedly
Inclining face, described squint face and top connection are 45 jiaos；Described top connection and drift size gauge tool screwed connection, and described top connection
Being connected through import with fishing tool, described top connection and fishing tool pass through screwed connection；Described drift size gauge tool another
End is equipped with set milling head.
The set milling head of described drift size gauge tool one end is that brazing connects.
The a length of 10mm of described screw thread.
The beneficial effects of the utility model are: drifting milling being salvaged and being ideally combined together, one flow chart is just
Completing above operation well, shortening more than 60% duty cycle, operating cost also can save more than 60%.
Brief description
Fig. 1 is structural representation of the present utility model.
Wherein: 1 for top connection, 2 for import, 3 for inclined plane, 4 for fishing tool, 5 for drift size gauge tool, 6 for set milling head.
Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is described further.
Integration tool is salvaged in the milling drifting of a kind of set, including drift size gauge tool the 5th, fishing tool the 4th, top connection the 1st, screw thread, set milling head 6,
Described drift size gauge tool 5 one end has import 2, and import 2 has squint face 3, described squint in horn-like, described import two ends
Face 3 and top connection 1 are in 45 jiaos；Described top connection 1 and drift size gauge tool 5 screwed connection, and described top connection 1 pass through import 2 with
Fishing tool 4 is connected, and described top connection 1 passes through screwed connection with fishing tool 4；Described drift size gauge tool 5 other end is equipped with
Set milling head 6.
The set milling head 6 of described drift size gauge tool 5 one end connects for brazing.
The a length of 10mm of described screw thread.
