A tool projectile (1) for a well workover, designed to cut into the tubing (2) of the equipment (100) for completing the well, having the top (3), and the equipment for completing the well contains a casing (4), in which the tubing is located, and a production packer (5) located between the casing and the tubing to form annulus (6) above the production packer, and the workover tool contains: longitudinal axis (7); a first end (8) of the tool string and a second end (9) of the tool string, the first end of the tool string being positioned closer to the top when plunged into the completion equipment; pipe-cutting module (10), containing a body (11), the first part (31) of the module, the second part (32) of the module and the cutting edge (12), made with the possibility of rotation around the longitudinal axis when extended relative to the body for cutting from the inside into the wall (14 ) tubing for separating the first part (15) of the tubing closest to the top from the second part (16) of the tubing; moreover, the workover tool additionally comprises a pipe punching module (20) containing a retractable punching element (21) configured to create at least one hole (22) in the wall of the first part to create fluid communication between the annulus and internal volume (23) of the tubing to obtain well control by circulating a fluid between them, and the punching module is located closer to the first end of the tool projectile than to the pipe cutting module, and the workover tool tool additionally contains a placement tool (17) for installing a plug (18) inside the second part of the tubing, wherein the placement tool is located in connection with the pipe cutting module so that the pipe cutting module is located between the pipe punching module and the placement tool, while the overhaul tool The well bore contains a rotary connection (33) between the second part (32) of the pipe-cutting module (10) and the placement tool (17). 2. The tool according to claim. 1, additionally containing a plug that forms the second end of the tool projectile when the tool is lowered into the tubing. 3. The projectile according to claim 1 or 2, in which the pipe-cutting module contains a cutting paw (24) having a first end (25) of the paw connected to the body with the possibility of rotation, and a second end (26) of the paw having a cutting edge. 4. Projectile according to any one of paragraphs. 1-3, in which the pipe cutting module comprises a first module part (31) and a second module part (32), wherein the second module part has a cutting foot and the second module part is rotatably connected to the first module part. 5. Projectile according to any one of paragraphs. 1-4, in which the retractable punching element contains a drill head (34) or a punching part (35). 6. Projectile according to any one of paragraphs. 1-5, in which the pipe punching module causes the retractable punching element to rotate to create at least one hole. 7. Projectile according to any one of paragraphs. 1-6 further comprising a cable (40) such that the tool is a cable-launched workover tool. 8. Projectile according to any one of paragraphs. 1-7, additionally containing a logging module (36) for determining the position of the tool projectile. 9. Downhole system (200), containing: wellbore (28); a casing (4) located in the wellbore; tubing (2) located at least partially inside the casing; a production packer (5) located between the casing and the tubing to form an annulus (6) above the production packer; and a tool projectile (1) for a workover of a well according to any one of paragraphs. 1-9, configured to be located inside the tubing. 10. The system of claim 9, wherein the workover tool further comprises a placement tool for placing a plug within the second portion of the tubing, the placement tool being located in connection with the pipe cutting module such that the pipe cutting module is located between the pipe punching module and placement tool. 11. The system of claim 9 or 10, further comprising a pump module (52) circulating heavy fluid down the annulus through at least one opening into the tubing. 12. The system according to any one of paragraphs. 9-11 further comprising equipment (53) configured to pull the first tubing section out of the wellbore and/or configured to insert a replacement tubing to replace the first section. 13. The system according to any one of paragraphs. 9-12, wherein the replacement tubing (60) comprises a tubing packer (61). 14. The system according to any one of paragraphs. 9-12, wherein the tubing packer includes an expandable sleeve (62). 15. A repair method for repairing well completion equipment (100) having an apex (3), wherein the well completion equipment comprises a casing (4) in which tubing (2) is located, and a production packer (5), located between the casing and the tubing to form an annulus (6) above the production packer, wherein the workover tool contains a cutting edge (12) rotatable around the longitudinal axis in the process of extension relative to the housing for cutting from the inside into a tubing wall (14) for separating the first tubing portion (15) closest to the top from the second tubing portion (16); place a tool projectile (1) for a well workover according to any one of paragraphs. 1-9 in the tubing, wherein the workover tool includes a cutting edge (12) rotatable around a longitudinal axis when extended relative to the housing for cutting from the inside into the wall (14) of the tubing to separate the first part (15) the tubing closest to the top from the second part (16) of the tubing; making at least one hole above the production packer in the first part by means of a pipe punching module; circulate heavy fluid through at least one orifice; cutting the wall of the tubing over the plug located inside the second part of the tubing, separating the first part and the second part of the tubing; pulling tool projectile from the tubing; and pulling the first part of the tubing from the casing.
