Description
Technical field
The present invention relates to a kind of band and repair the joint of drill, specifically, with the joint of repairing hole rock bit oppositely arranging, belong to field of oil drilling, also belong to drilling well field, ore deposit, ground.
Background technology
In trip-out process, because hole shrinkage, hole curvature be excessive etc., reason causes on drilling tool carries and being hampered, even can not spudding up and down, cause lock of tool drilling.In whole drilling assembly, the external diameter of stabilizer and drill collar is relatively large, thereby is prone to above problem.When processing these problems, normally first attempt the object that movable drilling tool by force reaches unfreezing, if failure only has injection special-purpose soaking liquid, utilize its physics chemical action to carry out unfreezing, above-mentioned conventional treatment method length consuming time, increases drilling cost.If still do not separate jam, drilling tool is stuck, and only pours out drilling tool more than stuck point, well filling sidetracking.
Summary of the invention
The object of the invention is for the undergauge bit freezing running in trip-out process, the problem of key-seating sticking, provide a kind of simple in structure, manufacturing cost and use cost is cheap, be provided with gear wheel joint upward, when on propose rotation during drilling tool, the band that gear wheel can be repaired the borehole wall is upward repaiied the joint of drill.
In order to achieve the above object, the present invention adopts following measure to realize, and the joint that provides a kind of band to repair drill comprises joint body and gear wheel, described joint body is divided into box end, joint body stage casing and pin end, the upper end of joint body is the box end that is provided with box, and the lower end of joint body is the pin end that is provided with pin thread, and box end and pin end inside are tubaeform, box end inside is long trumpet shape, upward, the lower end of pin end is micro-tubaeform to typhon mouth, and horn mouth down; Box end and pin end are equipped with screw thread, by screw thread, are connected with upper and lower drilling tool; Joint body axial centre has fluid passage, and joint body stage casing is axially arranged with gear wheel construction section, and the external diameter of gear wheel construction section is less than joint body maximum outside diameter; Described gear wheel construction section is provided with bit leg, and gear wheel is installed on bit leg, is distributed with cutting teeth on gear wheel.
Band of the present invention is repaiied the joint of drill, and 2～4 bit legs are radially installed in described gear wheel construction section equably, and gear wheel is installed on bit leg, and each gear wheel is installed towards top, installs after gear wheel, and the external diameter that 2～4 gear wheels impale is greater than the external diameter of joint body maximum.
Band of the present invention is repaiied the joint of drill, the external diameter of described gear wheel construction section is less than joint body maximum outside diameter, can facilitate the installation of gear wheel, simultaneously, when gear wheel is installed, should guarantee that the cutting teeth maximum outside diameter that can act on and the design size that will revise well of gear wheel matches.
The joint that band of the present invention is repaiied drill is positioned at the top of stabilizer or drill collar.Described box end is connected with upper and lower drilling tool by screw thread with pin end, and while above carrying rotation drilling tool, the cutting teeth on gear wheel can be around the axis revolution of joint body, and the while can be around roller axle rotation.In trip-out, run into blocked portion, when the joint that band is repaiied drill is positioned at the blocked portion position of hole shrinkage or the irregular caused bit freezing of hole diameter, on carry the cutting teeth incision borehole wall bit freezing position that drilling tool makes gear wheel, rotation drilling tool can make the cutting teeth of gear wheel produce effective shear action to the borehole wall.
The gear wheel of installing in the present invention and the basic structure of bit leg, with known various structures are general at present, do not repeat them here.
The joint that band of the present invention is repaiied drill has following beneficial effect:
1, to repair the joint design of drill simple for band of the present invention, and manufacturing cost and use cost is cheap.
2, the joint that band of the present invention is repaiied drill can solve large scale instrument, as the drilling tools such as stabilizer and drill collar jam problem in trip-out process, meanwhile, can effectively repair well, saves the processing time of bit freezing, improves drilling efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation that band of the present invention is repaiied the joint of drill.
In figure: 1-box end; 2-gear wheel; 3-cutting teeth; 4-bit leg; 5-gear wheel construction section; 6-joint body; 7-fluid passage; 8-pin end.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment 1: a kind of band is repaiied the joint of drill, its structure as shown in Figure 1, comprise joint body 6 and gear wheel 2, described joint body 6 is divided into box end 1, joint body stage casing and pin end 8, and the upper end of joint body is the box end 1 that is provided with box, the lower end of joint body is the pin end 8 that is provided with pin thread, box end 1 and pin end 8 inside are tubaeform, and box end 1 inside is long trumpet shape, and typhon mouth upward, the lower end of pin end 8 is micro-tubaeform, and horn mouth down; Box end 1 and pin end 8 are equipped with screw thread, by screw thread, are connected with upper and lower drilling tool; Joint body 6 axial centre have fluid passage 7, the gear wheel construction section 5 that joint body stage casing is axially arranged with, and the external diameter of gear wheel construction section 5 is less than joint body maximum outside diameter; Described gear wheel construction section 5 is provided with 2 bit legs 4, and gear wheel 2 is installed on bit leg 4, is distributed with cutting teeth 3 for rock cutting on gear wheel 2.
