Abstract
The utility model discloses a drilling and milling tool of falling drill nozzles. The drilling and milling tool comprises an upper joint, an outer tubular column and an inner tubular column; the drilling and milling tool is characterized in that a centralizing slide block is sleeved on the outer wall of the inner tubular column, the upper end of the inner tubular column is connected with the lower end of the upper joint through threads, the lower end of the inner tubular column is connected with a milling shoe, and a drainage hole is formed in the bottom part of the milling shoe; the inner tubular column and the milling shoe are inserted into the outer tubular column, the inner tubular column is centrally located in the outer tubular column through the centralizing slide block sleeved on the outer wall of the middle part of the inner tubular column, and the outer tubular column is connected with the middle part of the upper joint through threads; a locating pin hole is formed in the outer tubular column, and a locating pin is inserted into the locating pin hole for limiting the uplink height of the centralizing slide block; the lower end of the outer tubular column is set to be in a shifting hook shape; the drilling and milling tool disclosed by the utility model can be used for quickly drilling and milling stemming dropping into the falling drill nozzles, thereby capable of being extensively used for handling petroleum and natural gas drilling accidents.
Description
Technical field:
The utility model relates to instrument, is specifically related to the fish hydrophthalmia and bores milling tool.
Technical background:
In petroleum drilling operation down-hole accident processing procedure, drilling tool accident often occurs.The fish hydrophthalmia is easily stopped up by foreign material, is blocked if thread making is salvaged rear drilling tool, can't, by the circulation unfreezing, also can't implement the breakouting pack of dynamite operation.
For this accident treatment difficult problem, generally adopt coiled tubing water flowing eye, but this technical costs is high, the activity duration is long, and economic loss is large; Also can directly use junk mill milling hydrophthalmia blocking portion drilling tool, but because of the drilling tool wall thickness, this method speed is extremely slow.Simultaneously, exist the bottom hydrophthalmia to be continued the risk of stopping up during the fish of milling top, strengthened the accident intractability, even cause well to be scrapped and the well filling sidetracking.
The utility model content:
Technical problem to be solved in the utility model is to provide the fish hydrophthalmia to bore milling tool.
The technical solution of the utility model is: the fish hydrophthalmia bores milling tool, comprises top connection, outer tubing string and interior tubing string; Be characterized in: the sheathed righting slide block of the outer wall of described interior tubing string, in this, tubing string upper end is connected with the lower end of described top connection by screw thread, and the lower end of described interior tubing string connects junk mill, and the bottom of junk mill is provided with outage; Described interior tubing string and junk mill insert in described outer tubing string, by the righting slide block that is set in described interior tubing string middle part outer wall, described interior tubing string are located between two parties in described outer tubing string, enter smoothly the fish hydrophthalmia to ensure interior tubing string; Should by screw thread, be connected with the middle part of described top connection by outer tubing string; On described outer tubing string, be provided with dowel hole, alignment pin inserts in described dowel hole spacing to the upper line height of righting slide block; Be that alignment pin is controlled the upper line height of righting slide block under the drilling fluid buoyancy; The lower end of described outer tubing string is set to dial hook-shaped.
The beneficial effect that fish hydrophthalmia described in the utility model bores milling tool is: the utility model is the obstruction in ground auger mill off fish hydrophthalmia comparatively fast, for implementing breakouting pack of dynamite, create conditions, be conducive to improve the accident treatment progress, shorten the accident treatment time, reduce causality loss, can be widely used in oil, the operation of gas drilling accident treatment.
The accompanying drawing explanation:
Fig. 1 is the structural representation that fish hydrophthalmia described in the utility model bores milling tool;
The specific embodiment:
Referring to Fig. 1, the fish hydrophthalmia bores milling tool, consists of top connection 1, outer tubing string 2, interior tubing string 3, righting slide block 11 and junk mill 12; Top connection 1 upper end arranges internal thread 4, and top connection 1 middle part arranges external screw thread 5, and top connection 1 lower end arranges external screw thread 6; Outer tubing string 2 upper ends arrange internal thread 7, and interior tubing string 3 upper ends arrange external screw thread 9; Described righting slide block 11 is set in the outer wall of described interior tubing string 3; Described interior tubing string 3 upper ends are connected with the lower end of described top connection 1 by screw thread, and the lower end of described interior tubing string 3 connects junk mill 12, and the bottom of junk mill 12 is provided with outage; Described interior tubing string 3 inserts in described outer tubing string 2 with junk mill 12, makes described interior tubing string 3 in the interior location placed in the middle of described outer tubing string 2 by the righting slide block 11 that is set in described interior tubing string 3 outer walls; Should by screw thread, be connected with the middle part of described top connection 1 by outer tubing string 2; On described outer tubing string 2, be provided with dowel hole, alignment pin 10 inserts in described dowel hole spacing to the upper line height of righting slide block 11; The lower end of described outer tubing string 2 is set to dial hook-shaped 8; This righting slide block 11 is used wood materials, and the loss prevention well that breaks down causes complexity; These righting slide block 11 internal diameters are greater than interior tubing string external diameter and are less than the junk mill external diameter, the anti-natural slippage of righting slide block 11.
During use, utilize outer tubing string to introduce fish, interior tubing string bores and mills.Specifically, by under instrument, arriving top of fish, rinse top of fish 10～15 minutes, guarantee to be inserted in smoothly top of fish; While being inserted in fish, first by the outer tube column sleeve outside fish, then junk mill is penetrated to the fish hydrophthalmia, according to circumstances the judgement instrument situation that is hampered.
