Description
Technical Field
The invention relates to the technical field of oil and gas exploitation equipment, in particular to a sand removal deflector 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. During the drilling process, due to the conditions of stratum deformation, drill bit abrasion, rock debris spreading and attaching and the like, the size of a borehole can not reach the designed size, so that the drilling is easy to be blocked, the casing is difficult to run, and the like.
Disclosure of Invention
The invention aims to provide a sand removal deflector for well drilling aiming at the defects of the prior art, and the specific scheme is as follows:
a sand removal deflector for well drilling comprises a body, wherein a channel is formed in the body along the axial direction, internal threads and external threads used for being in threaded connection with a drill rod are respectively arranged at two ends of the body, a working section is arranged in the middle of the body, a plurality of V-shaped grooves are formed in the working section along the axial direction, and high-abrasion-resistant alloy blocks are inlaid in the surfaces of convex edges forming the V-shaped grooves.
Based on the above, the number and the included angle of the V-shaped grooves are not limited.
Based on the above, the number and arrangement of the high wear-resistant alloy blocks are not limited.
Compared with the prior art, the invention has outstanding substantive characteristics and remarkable progress, and particularly has the following advantages:
in the using process of the invention, the sand removal deflector is driven to rotate along with the rotation of the drill rod column, the returned drilling fluid is stirred by utilizing the V-shaped groove on the surface of the working section of the body, and the drilling fluid obtains high-speed rotation power, thereby impacting and scouring the well wall, and the rock debris adhered to the well hole is carried to the ground after being loosened and falling.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a sectional view taken in the direction of a-a in fig. 1.
In the figure: 1. a body; 2. an internal thread; 3. an external thread; 4. a channel; 5. a working section; 6. a rib; 7, V-shaped grooves; 8. high wear-resistant alloy block.
Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments.
Examples
As shown in fig. 1-2, the invention provides a sand-cleaning deflector for well drilling, which comprises a body 1, wherein a channel 4 is axially arranged in the body 1, internal threads 2 and external threads 3 for being screwed with a drill rod are respectively arranged at two ends of the body 1, a working section 5 is arranged in the middle of the body 1, a plurality of V-shaped grooves 7 are axially arranged on the working section 5, and high-wear-resistance alloy blocks 8 are embedded in the surfaces of convex ribs 6 forming the V-shaped grooves 7.
The number and included angle of the V-shaped grooves 7 are not limited.
The number and arrangement of the high wear-resistant alloy blocks 8 are not limited.
The invention has the specific working principle that: in the using process of the invention, the sand removal deflector is driven to rotate along with the rotation of the drill rod column, the returned drilling fluid is stirred by utilizing the V-shaped groove on the surface of the working section 5 of the body 1, and the drilling fluid obtains high-speed rotation power so as to impact and scour the well wall, so that the rock debris adhered to the well hole is carried to the ground by the drilling fluid after loosening and falling, the efficient trimming of the well hole is realized, and the construction efficiency is improved.
Finally, it should be noted that: the above examples are only intended 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, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
