Description
Technical field
The utility model belongs to geological drilling field, cuts illing-drilling head more particularly, to a kind of staged.
Background technique
Heavy caliber drilling well generally refers to open-hole aperture in 500mm or more drilling well.Heavy caliber drilling well is opened in subterranean resource at present
Hair, basic engineering construction and processing, underground industrial plants build etc. fields using more and more extensive.Because of its tripping in casing bore
Greatly, thickness of pipe wall, from great, during down tube probably due to casing inside and outside differential pressure it is excessive be more than casing strength, pipe workpiece quality
Or many-sided combined cause, casing can be made to deform even and ruptured, and since casing self weight is excessive or deformation is serious, so
It is difficult to be raised to replace new casing, this just needs to carry out tunica pipe deformation section to cut milling processing, and in the case where siphunculus is unobstructed later
Enter more small-bore casing.Casing deformation accident happens occasionally in drilling field, and under prior art conditions, the milling of cutting used is bored
Head is usually single bore, and what is be easy to produce leads tiltedly, in turn results in and cuts illing-drilling head and split pipe and steel plate of riving along what casing cut milling
The problem of possibly can not cutting off.
Summary of the invention
In view of this, the utility model, which is directed to a kind of staged, cuts illing-drilling head, with the use of righting bucket, screw terminal,
Hard alloy particle layer on the thick walled steel tube and thick walled steel tube lateral wall of stairstepping setting, realizes classification and cuts milling, avoid
That cuts illing-drilling head leads oblique situation, effectively increases and cuts milling quality and efficiency.
In order to achieve the above objectives, the technical solution of the utility model is achieved in that
A kind of staged cuts illing-drilling head, the righting bucket including hollow cylindrical；Righting bucket bottom end is equipped with conical head, conical head
Top is equipped with screw terminal；Righting bucket top is equipped with multiple and different diameters and axle center is overlapped the thick walled steel tube of setting, multiple heavy wall steel
Pipe diameter is descending to be arranged at stairstepping, the maximum thick walled steel tube of diameter with righting bucket top is concentric is fixedly connected；Diameter
The smallest thick walled steel tube side wall top is equipped with hard alloy particle layer, and thick walled steel tube lateral wall is equipped with hard alloy particle layer,
Hard alloy particle layer is equipped at the top of righting bucket lateral wall.
In the practical application of the utility model, screw terminal is connect with drilling rod, and drilling rod promotion originally cuts illing-drilling head to well inner sleeve
At pipe deformation, during drill bit cuts milling, maximum distortion section will be cut by staged first cuts milling at the top of illing-drilling head and even shuts off, most
Large deformation part cut milling it is unobstructed after, with the further tripping in of drilling tool, the nubbin of maximum distortion section and deform relatively weak
Part will be cut illing-drilling head step by step from center to circumscribed milling from staged, realize classification processing.It effectively avoids single bore from cutting milling to bore
Head with the increase for cutting milling depth, the casing wall steel plate of incision enter it is issuable after righting bucket lead oblique effect, milling is cut in reduction
Drill bit along casing cut milling split pipe and rive steel plate possibly can not cut off the problem of.
Further, there are five thick walled steel tube is set.
Further, support frame is equipped with inside conical head.
Further, righting bucket is the seamless thick walled steel tube of 825mm.
Further, the maximum thick walled steel tube of diameter is the seamless thick walled steel tube of 750mm.
Further, the smallest thick walled steel tube of diameter is the seamless thick walled steel tube of 310mm.
Compared with the existing technology, a kind of staged of the utility model cuts illing-drilling head, has the advantage that
A kind of staged of the utility model cuts illing-drilling head, the heavy wall steel being arranged with the use of righting bucket, screw terminal, stairstepping
Hard alloy particle layer on pipe and thick walled steel tube lateral wall, realizes classification and cuts milling, avoid cut illing-drilling head lead oblique situation,
It effectively increases and cuts milling quality and efficiency.
