Abstract
The utility model provides a well finisher for well drilling, which comprises a body, the passageway has been seted up along its axial to the inside of body, and body one end is equipped with the internal thread that is used for with the drilling rod spiro union, and the other end of body is equipped with the external screw thread that is used for with the drilling rod spiro union, and the middle part of body is the working section, many helicla flutes have been seted up along circumference in the surface of working section, all be equipped with the cutting teeth on the both sides bead of helicla flute, the cutting teeth distributes the both ends of the surface of bead. The utility model provides a well trimmer for well drilling, the cutting tooth that sets up on its working section bead can carry out high-efficient the maintaining to the well when drilling down, tripping, avoids the emergence of card brill phenomenon, effectively improves the efficiency of construction, saves construction cost.
Description
Technical Field
The utility model relates to an oil and gas drilling equipment technical field, concretely relates to well finisher for well drilling.
Background
In the process of exploiting the petroleum and natural gas, well bores with different diameters are drilled from the ground by a drilling machine to reach a specified oil-gas layer, and a casing with corresponding size is put in to assist in well cementation to form an oil-gas channel. In the drilling process, due to stratum deformation, the size of a borehole cannot reach the designed size due to drill bit abrasion, the quality of the borehole is poor, drill sticking is easily caused, and the drilling efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the not enough of prior art, provide a well finisher for well drilling for it warp to maintain the well, improves the well quality, has improved, has drilled efficiency down, and concrete scheme is as follows:
a well hole trimmer for well drilling comprises a body, wherein a channel is formed in the body along the axial direction of the body, an internal thread used for being in threaded connection with a drill rod is arranged at one end of the body, an external thread used for being in threaded connection with the drill rod is arranged at the other end of the body, a working section is arranged in the middle of the body, a plurality of spiral grooves are formed in the surface of the working section along the circumferential direction, cutting teeth are arranged on protruding edges on two sides of each spiral groove, and the cutting teeth are distributed at two ends of the outer surface of the protruding edge.
The utility model discloses relative prior art has substantive characteristics and progress, specifically speaking, the utility model has the following advantages:
the utility model provides a well trimmer for well drilling, the cutting tooth that sets up on its working section bead can carry out high-efficient the maintaining to the well when drilling down, tripping, avoids the emergence of card brill phenomenon, effectively improves the efficiency of construction, saves construction cost.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure: 1. a body; 2. a channel; 3. an internal thread; 4. an external thread; 5. a working section; 6. a helical groove; 7. a rib; 8. and (4) cutting teeth.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
Examples
As shown in fig. 1, the utility model provides a well finisher for well drilling, including body 1, passageway 2 has been seted up along its axial in the inside of body 1, and 1 one end of body is equipped with and is used for the internal thread 3 with the drilling rod spiro union, and the other end of body 1 is equipped with and is used for the external screw thread 4 with the drilling rod spiro union, and the middle part of body 1 is working section 5, many helicla flutes 6 have been seted up along circumference on the surface of working section 5, all be equipped with cutting teeth 8 on the both sides bead 7 of helicla flute 6, cutting teeth 8 distribute and be in the both ends of the surface of bead 7.
The utility model discloses concrete theory of operation: the utility model discloses be applied to on the probing post, its both ends all with the drilling rod spiro union, install it in probing post suitable position during the use, follow the drilling and insert the well under the probing post.
When drilling, the cutting teeth 8 at the lower end of the rib 7 cut the well wall at the deformed position of the well hole, so that the well hole reaches the designed size; when the drill bit is started, the cutting teeth 8 at the upper ends of the ribs 7 cut the well wall at the deformed position of the well hole, so that the well hole reaches the design size, the drill bit is prevented from being stuck in the process of starting the drill bit, and the drilling efficiency is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
