Abstract
The utility model discloses a kind of gauge structure of directional well drill bit, comprise bit body, described bit body has been made into integration boss, the periphery wall of described boss is evenly distributed with the first notch and the second notch, deburring tooth and gauge teeth is plugged with respectively in described first notch and the second notch, described deburring tooth is fixed by the first screw be arranged on boss, and described gauge teeth is fixed by the second screw be arranged on boss; The utility model not only ensure that the gauge area of bit body, can not reduce the lateral cutting ability of bit body simultaneously, and has flexible, the practical advantage of use.
Description
Technical field
The utility model is specifically related to a kind of gauge structure of directional well drill bit, belongs to directional well bit technique field.
Background technology
PDC drill bit is a kind of synthetic diamond core bit of extensive use in present oil, natural gas drilling.Bit gauge protection except maintenance borehole diameter, on the steering capability of drill bit and stability impact comparatively large, its structure is determined by gauge length, gauge width and gauge shape.Generally speaking, stratum abrasiveness is larger, and gauge area should strengthen, and existing PDC drill bit design only considered the gauge effect of gage surface, the major measure increasing gauge area adopts the design of spiral gauge, but usually increase the lateral cutting ability that gauge area can reduce drill bit.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model does not reduce the gauge structure of the directional well drill bit of the lateral cutting ability of drill bit while being to provide a kind of gauge area increasing PDC drill bit.
The gauge structure of directional well drill bit of the present utility model, comprise bit body, described bit body has been made into integration boss, the periphery wall of described boss is evenly distributed with the first notch and the second notch, deburring tooth and gauge teeth is plugged with respectively in described first notch and the second notch, described deburring tooth is fixed by the first screw be arranged on boss, and described gauge teeth is fixed by the second screw be arranged on boss.
Further, described first notch is rectangular-shaped.
Further, described second notch is cylindrical shape.
The utility model beneficial effect: the gauge structure not reducing the directional well drill bit of the lateral cutting ability of drill bit while a kind of gauge area increasing PDC drill bit of the present utility model; During work, bit body pierces in directional well, by the setting of gauge teeth, ensure that the gauge area of directional well, by the setting of deburring tooth, improves lateral cutting ability of the present utility model, improve stability during bit operation; Simultaneously because deburring tooth is fixed by the first screw be arranged on boss, gauge teeth is fixed by the second screw be arranged on boss, user in use can adjust the position of gauge teeth and deburring tooth neatly, improves use flexibility of the present utility model.The utility model not only ensure that the gauge area of bit body, can not reduce the lateral cutting ability of bit body simultaneously, and has flexible, the practical advantage of use.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the plan structure schematic diagram after deburring tooth amplifies.
Detailed description of the invention
The gauge structure of directional well drill bit as depicted in figs. 1 and 2, comprise bit body 1, described bit body 1 has been made into integration boss 2, the periphery wall of described boss 2 is evenly distributed with the first notch 3 and the second notch 4, deburring tooth 5 and gauge teeth 6 is plugged with respectively in described first notch 3 and the second notch 4, described deburring tooth 5 is fixed by the first screw 7 be arranged on boss 2, described gauge teeth 6 is fixed by the second screw 8 be arranged on boss 2, described first notch 3 is rectangular-shaped, and described second notch 4 is cylindrical shape.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
