The basis of this group of inventions is a solution to the problem that allows you to reliably operate the tool, ensure the tightness of the tool and direction, expand the possibilities of their use.

The technical result of the group of inventions consists in the implementation of a tool with a guide and a prefabricated case during their functional interaction, in the presence of a gasket and seals for them, in the possibility of using various design devices as a plug (Option 1) and a ball valve with a cable (Option 2 )

According to the group of inventions (Option 1), this problem is solved due to the fact that the tool for installing the pipe string direction into the well on the shelf, made with grooves and grooves, have the possibility of lowering pipe casing pipe with equipment for cement work into the well on the drill pipe string.

The tool consists of a guide with emphasis and a precast housing.

The prefabricated housing is made with a seal and consists of smaller and larger housings with seals.

The guide is made with a threaded end for the drill pipe string and a threaded end for the pipe string with equipment for cement work, as well as with a thread for the nut.

The nut is equipped with a key and an end conical surface, on the opposite side of which a protrusion is made, interacting with the groove of the indicator pin on the assembly case.

The prefabricated housing is made with fingers for radial movement of it and for interaction with a guide and a groove of direction, also with stops having the ability to interact with grooves of direction.

In addition, a shear transport screw is installed on the prefabricated housing, partially placed in the guide and blocking its rotation relative to the prefabricated housing during the descent.

In this case, a through hole is made in the prefabricated housing and a plug is installed.

Option 1 and Option 2.

A tool for installing a pipe string of direction 1 into a well on a shelf, made with grooves 2 and a groove 3, can be lowered into a well on a string of drill pipes 4 pipe columns 5 with equipment for cement work.

The tool consists of a guide 6 with a stop 7 and a precast housing 15.

The prefabricated housing 15 is made with a seal 18.

The precast housing 15 consists of a smaller housing with a seal 16 and a larger housing with a seal 17.

The guide 6 is made with a threaded end 8 for the drill string 4 and a threaded end 9 for the pipe string 5.

Also, the guide 6 is made with thread 10 for nut 11.

The nut 11 is provided with a key 13 and an end conical surface 12.

On the opposite side, the end conical surface 12 is a protrusion 14.

The protrusion 14 has the ability to interact with the groove 21 of the indicator pin 20.

The indicator pin 20 is mounted on the precast housing 15.

The prefabricated housing 15 is made with fingers 19 for radial movement of it and for interaction with the guide 6 and the groove 3 of the direction 1.

The prefabricated housing 15 is made with stops 23 having the ability to interact with the grooves 2 directions 1.

In addition, a shear transport screw 22 is installed on the precast housing 15, partially placed in the guide 6 and blocking its rotation relative to the precast housing 15 during the descent of direction 1.

Option 1

In the precast housing 15, a through hole 24 is made and a plug 25 is installed.

Option 2

In the precast housing 15, a through hole 24 is made and a ball valve 26 is installed with a cable 27.

The tool is used as follows.

In FIG. 3 (Option 1) and FIG. 6 (Option 1) shows the position of the tool on the platform before starting work.

The nut 11 is in the upper position when the indicator pin 20 is fully extended from the precast housing 15.

Shear transport screw 22 is unscrewed in the precast housing 15 to prevent contact with the guide 6, which has the ability to rotate relative to the precast housing 15.

The fingers 19 are buried in the prefabricated housing 15 and do not come in contact with the nut 11.

In FIG. 1 (Option 1) and FIG. 4 (Option 1) shows the position of the tool ready for descent into the well.

A string of drill pipes 4 is screwed onto the threaded end 8 of the tool guide 6.

On the threaded end 9 of the tool guide 6, a pipe string 5 with equipment for cement work is screwed.

The tool is lowered on the drill pipe string 4 until the stops 23 of the assembly case 15 fall into the grooves 2 of direction 1.

Then rotate the drill string 4 to the left.

In this case, the nut 11 having the right-hand thread will lower to the lower position by spreading the fingers 19 in the groove 3 of the direction 1 by the end conical surface 12.

The indicator pin 20 will lower to the lower position, indicating that the nut 11 has stopped in the desired position.

The drill string 4 is fixed for descent.

In the tool, the shear transport screw 22 is screwed into the guide 6, blocking the possibility of its rotation in the precast housing 15 and the nut 11.

A plug 25 is installed in the through hole 24 of the collection case 15 (Option 1).

A ball valve 26 is installed in the through hole 24 of the collection case 15 in the open position in order to bleed air from under the tool at the initial moment of descent. A cable 27 is attached to the handle of the ball valve 26 to close the ball valve 26 after air release. As soon as the tool disappears under water and the air from the ball valve 26 stops flowing, the ball valve 26 is closed using the cable 27 (Option 2).

On the drill pipe string 4, the entire arrangement from the platform is lowered into the water and into the well.

Continue to lower the tool into the well until the bottom.

Then produce cementing direction 1 and the rise of the tool.

Why do a little tension on the drill string 4 and rotate it to the right.

In this case, the nut 11 rises and raises the indicator pin 20, and as soon as the end conical surface 12 of the nut 11 leaves fingers 19, they will be shifted into the precast housing 15 by the axial movement along the direction 1 due to the angle of attack of the groove 3 by 45 degrees.

The tool is lifted to the platform.

The claimed group of inventions "A tool for installing a pipe string direction in the construction of oil and gas wells on the shelf. Variants ”includes components and parts that are widely used in the construction of oil and gas wells, and the experimental work on the use of the tool in the construction of oil and gas wells on the shelf determines, according to the applicant, the group of inventions meets the criterion of“ industrial applicability ”.
