Technical Field

[0001] The utility model relates to the technical field of oil drilling, in particular to a rock cuttings removal tool. Background Art

[0002] Cuttings cleaning is the process of pumping mud to the bottom of the well and returning it to the surface with cuttings. During underground operations, cleaning the cuttings on the well wall is an important step. If the cleaning is not in place, the smooth progress of the drilling process and the safety of the wellbore cannot be ensured; if the cuttings are not removed thoroughly, it may cause partial or complete blockage of the wellbore, increasing the difficulty and risk of subsequent treatment.

[0009] Furthermore, in the present invention, the first ridge, the second ridge, and the third ridge are all multiple and are circumferentially and equidistantly connected to the shell.

[0010] Furthermore, in the present invention, the surfaces of the first ridge, the second ridge, and the third ridge are all coated with a high-wear-resistant alloy.

[0011] Beneficial effects: The technical solution of this application has the following technical effects:

[0012] The utility model divides the shell into a smooth section, a first slope section, and a second slope section, and the slope angles of the first slope section and the second slope section are both 30°, so as to make the mud flow into the well more smoothly and make the performance of the rock chip removal tool more stable when working; the setting of the first ridge, the second ridge, and the third ridge can make the rock chips in the wellbore move continuously into the well, and the rock chips on the bottom and wall of the barrel are fully mixed under the rotation of the drill pipe when the rock chip removal tool continuously moves into the well. As the mud is continuously added, the rock chips are returned to the ground together with the mud, thereby effectively removing the rock chips in the wellbore, which not only improves the safety of the wellbore, but also ensures the smooth progress of the drilling work.

[0019] In order to better understand the technical content of the present invention, specific embodiments are given and described as follows in conjunction with the accompanying drawings. Various aspects of the present invention are described in this disclosure with reference to the accompanying drawings, in which many illustrative embodiments are shown. The embodiments of the present disclosure are not necessarily defined to include all aspects of the present invention. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in the present invention are not limited to any implementation method. In addition, some aspects disclosed in the present invention can be used alone or in any appropriate combination with other aspects disclosed in the present invention.

[0020] like Figure 1-Figure 2 As shown, a rock cuttings removal tool comprises: a shell 1, which is cylindrical and has thread lines at both ends of the shell 1, and the shell 1 comprises: a smooth section 11, the two ends of the smooth section 11 are a first slope section 12 and a second slope section 13, and the slope angles of the first slope section 12 and the second slope section 13 are both 30°; a first ridge 14, one end of which is connected to the side wall of the first slope section 12, and the other end is connected to the side wall of the smooth section 11; a second ridge 15, which is connected to the side wall of the smooth section 11; a third ridge 16, one end of which is connected to the side wall of the second slope section 13, and the other end is connected to the side wall of the smooth section 11.

[0021] In the present application, both ends of the shell 1 are threaded structures for connecting to the drill pipe. The slope angles of the first slope section 12 and the second slope section 13 are both 30°, so that the mud can flow more smoothly into the well, and at the same time, the performance of the rock chip removal tool can be more stable during operation; the setting of the first ridge 14, the second ridge 15, and the third ridge 16 can make the rock chips in the wellbore move continuously into the well, and the rock chips on the bottom and wall of the barrel are fully mixed under the rotation of the drill pipe. As the mud is continuously added, the rock chips are returned to the ground together with the mud, thereby effectively removing the rock chips in the wellbore, which not only improves the safety of the wellbore, but also ensures the smooth progress of drilling work.

[0022] Furthermore, the first ridge 14 and the third ridge 16 both include: straight edges 17 and oblique edges 18. The straight edges 17 are connected to the side walls of the smooth section 11, the oblique edges 18 on the first ridge 14 are connected to the side walls of the first sloped section 12, and the oblique edges 18 on the third ridge 16 are connected to the side walls of the second sloped section 13.

[0023] In the present application, the oblique edge 18 is parallel to the first slope section 12 and the second slope section 13 respectively, and the straight edge 17 is parallel to the smooth section 11. At the same time, the straight edge 17 and the oblique edge 18 form a "V"-shaped structure. The "V"-shaped structure is conducive to guiding the mud entering the wellbore, and at the same time can increase the turbulence of the mud around the rock cutting removal tool, so that the rock cuttings in the wellbore can be more completely and effectively removed.

[0024] Furthermore, the second rib 15 is a trapezoidal structure, the large end of which is connected to the side wall of the smooth section 11. The trapezoidal structure of the second rib 15 is also intended to make the removal of cuttings in the wellbore smoother and more stable.

[0025] Furthermore, the first rib 14, the second rib 15, and the third rib 16 are multiple and are equidistantly connected to the shell 1 in a circular manner. In actual application, the number of the first rib 14, the second rib 15, and the third rib 16 can be determined according to the diameter of the shell 1, and the number of the three is consistent; the equidistant distribution is to ensure that when the mud flows in, the stirring speed of the drill pipe in each direction is consistent when it is stirred, so that the mud and the rock cuttings are completely and fully mixed, thereby improving the ability to carry rock cuttings.

[0026] Furthermore, the surfaces of the first ridge 14, the second ridge 15, and the third ridge 16 are all coated with a high-wear-resistant alloy coating. The high-wear-resistant alloy coating is made using laser cladding technology, which uses a high-energy-density laser beam to melt metal powder or wire and quickly solidify it on the surface of the first ridge 14, the second ridge 15, and the third ridge 16 to form a coating with special properties. This technology can significantly improve the wear resistance, corrosion resistance, and oxidation resistance of the parts, thereby increasing the service life of the rock chip removal tool.

[0027] The standard parts used in this application document can all be purchased from the market, and can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, this application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.

[0028] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
