This technical solution was adopted as the closest analogue of this utility model.

The unit of the closest analogue contains two winches: a drill and an auxiliary one installed on the frame; devices for lifting the casing as part of the installation of the closest analogue are not provided and this reduces its performance.

The present utility model is based on the solution of a problem that makes it possible to increase and expand operational qualities.

The technical result of this utility model is to increase the stroke of the supply cylinder, to accelerate the hoisting operations and to perform shock-rope drilling, to ensure the free passage of the winch cable to the wellhead, to increase the strength of the mast and the possibility of additional operations to raise the casing string .

According to the utility model, this problem is solved due to the fact that the exploratory drilling installation includes a mast with a tackle system and with the possibility of installation in horizontal transport and vertical working positions, a cargo winch, a control panel, hydraulic drives, drilling and auxiliary equipment mounted on the frame car chassis.

The mast is made with upper and lower crown blocks for mounting the tackle system located, respectively, in the upper and lower parts of the mast.

The mast has a U-shape, welded from a channel with transverse beams, and is reinforced with additional metal construction from profile pipes.

The mast is equipped with a carriage for moving the rotator along the inner profile of the mast.

The carriage is made with a body in the form of a welded frame, four upper rollers rigidly fixed in the carriage body with its sliding bearing centering the mast inside the mast, and four lower rollers allowing adjustment of the position of the carriage inside the mast.

The carriage is made with a slider with a rotator mounted on it with the ability to move from right to left along the carriage and vice versa using a rotator retraction hydraulic cylinder.

A cargo winch is installed in the upper part of the mast, on top of which a bracket is placed for hoisting operations.

In the lower part of the mast, a guide beam is fixed on which a casing lifting device is installed, made in the form of a gripping mechanism with the possibility of axial movement along the guide beam using two hydraulic cylinders controlled from the control panel.

The exploratory drilling installation comprises a mast 3 with the possibility of installation in horizontal transport and vertical operating positions, a cargo winch 4, a control panel 5, hydraulic drives, drilling and auxiliary equipment installed on the frame 2 of the automobile chassis 1.

The mast is made with the upper 7 and lower 8 crown blocks for mounting the tackle system 6, located, respectively, in the upper and lower parts of the mast 3.

The mast 3 has a U-shape welded from a channel with transverse beams 9 and is reinforced with additional metal construction from profile pipes 10.

The mast 3 is equipped with a carriage 11 for moving the rotator along the inner profile of the mast 3.

The carriage 11 is made with a housing 12 in the form of a welded frame, four upper rollers 13, rigidly fixed in the housing 12 of the carriage 11 with its centering inside the mast 3 by a sliding bearing 14, and four lower rollers 15, allowing adjustment of the position of the carriage 11 inside the mast 3.

The carriage 11 is made with a slider 16 with a rotator mounted on it with the possibility of moving from right to left along the carriage 11 and vice versa using the hydraulic cylinder of the retractor 17 of the rotator.

A cargo winch 4 is installed in the upper part of the mast 3, on top of which 18 a bracket 19 is placed for hoisting and lifting operations.

In the lower part of the mast, a guide beam 20 is fixed on which a casing lifting device 21 is mounted, made in the form of a gripping mechanism with the possibility of axial movement along the guide beam 20 using two hydraulic cylinders 22 controlled from the control panel 5.

The operation of the installation is as follows.

The installation consists of a base chassis 1 and attachments.

Attached equipment included in the exploratory drilling installation is mounted on its own frame 2, welded construction, from steel profiles. Frame 2 with the help of ladder rigs is attached to the side members of the chassis 1 of the car.

The mast 3 is mounted on special hinges on the frame 2. In the working position, the mast 3 is fastened with clamps on the frame 2, and in the transport position, the mast 3 is laid on the front support with the hydraulic mast lifting cylinder 3 and is attached to it with a special clamp. For the convenience of work during hoisting operations, as well as for centering the tool at the bottom of mast 3, there is a table and a beam for mounting support jacks is made, with the help of which the transport base is unloaded and mast 3 is set upright.

A rotator with a hydraulic actuator mounted on the carriage 11 with a shift moves along the mast 3. The carriage 11 is mixed on the rollers 13 and 15 along the internal profile of the mast 3. During drilling, the rotator provides the extension of the drill pipe without breaking the rock cutting tool from the bottom and, together with the tackle system 6, performs the work of lowering and raising the tool and feeding it during drilling. Using the rotator is also screwing-unscrewing drill pipes. A cargo winch 14 is installed in the upper part of the mast 3, which has an equal rotation speed of the drum in both directions and is capable of freely dropping the load. In the lower part of the mast 3 is installed a device for lifting the casing string 21.

The implementation of the mast with upper and lower crown blocks for the installation of tackle systems improves operational performance.

The implementation of the mast U-shaped, welded from a channel with transverse beams, and reinforcing the mast with additional metal construction from profile pipes gives it increased strength.

The supply of the mast with the carriage for moving the rotator along the inner profile of the mast, which ensures the extension of drill pipes without tearing the rock cutting tool from the bottom and, together with the tackle system, carries out the work of lowering and raising the tool and drilling, as well as providing screwing-unscrewing of drill pipes, expands performance.

Carriage construction with upper rollers rigidly fixed in the carriage body and with lower rollers allowing adjustment of the position of the carriage inside the mast and ensuring a tight fit of the rollers to the inner surface of the channel, including a tight fit of the carriage rollers along the entire length of the mast, eliminating the possibility of wedging carriage and distortions during operation, improves performance.

The implementation of the carriage with a slider with a rotator mounted on it with the ability to move from right to left along the carriage and vice versa with the help of a hydraulic cylinder for rotator retraction, which allows working with a cargo winch, extends the performance.

The installation of a cargo winch in the upper part of the mast, on top of which there is a bracket for hoisting operations, which has an equal speed of rotation in both directions and is able to freely discharge the load, increases and extends the operational qualities of the installation.

The fastening of the guide beam in the lower part of the mast and the installation of a casing lifting device on it expand the operational qualities.

The claimed exploratory drilling rig was manufactured industrially by LLC “Drilling Technologies Plant” and the pilot works on drilling geophysical and structural-exploratory wells determine, in the applicant’s opinion, compliance with its criterion of “industrial applicability”.
