Self-propelled hydraulic rig

The utility model relates to the field of drilling equipment and relates to self-propelled drilling rigs used in well drilling.

Known self-propelled hydroficated drilling rig, adopted for the prototype, containing a transport base, platform, mast, feed cylinder, crown block with rollers, a movable rotator with an oil seal, pipe holder (book. Reference engineer for drilling exploration wells, t. 1 edited by E. A. Kozlovsky, M., "Nedra, 1984, p. 120). In this drilling rig, using standard drill pipes (for example, 3 m), it becomes necessary to use long-length (mast length must exceed the stroke of the movable rotator) tubular or spatial type of mast, which receive reactive torque from the work of the rotator along the entire length of its stroke, which determines the increased metal consumption designs.

The objective of the utility model is to reduce the metal consumption and the ability to use standard drill pipes, twice the length of the stroke of the movable rotator.

To solve this problem, in a self-propelled hydroficated drilling rig containing a transport base, platform, mast, feed cylinder, a crown block with rollers, a movable rotator with an oil seal, a pipe holder, the unit is equipped with a winch with a cable and a driving rod connected through an oil seal to the cable of the said winch, and having a length of at least the stroke of the movable rotator, the latter having the ability to move along the drive rod, and the pipe holder is fixed to the ground.

The utility model is illustrated by drawings, which depict:

in FIG. 1 is a self-propelled hydroficated drilling rig (general view) in FIG. 2 is a diagram illustrating the operation of the drilling rig.

Self-propelled hydroficated drilling rig (see Fig. 1) contains a transport base 1, platform 2, mast 3, a hydraulic cylinder of the feed mechanism 4, crown block 5 with rollers, a movable rotator 6 with an oil seal 7, a pipe holder 8. The movable rotator 6 is made through and has the ability displacements along the driving rod 9. The stuffing box 7 is rigidly connected to the driving rod 9 and to the cable 10 of the winch 11. The pipe holder 8 is mounted on the ground and fixed on it using, for example, support jacks.

The inventive device allows you to solve the task.

Indeed, the self-propelled hydroficated installation is equipped with a lead bar 9, connected through a gland 7 with a cable 10 of a winch 11, which allows, when drilling a well in series - first using a rotator 6, and then using a winch 11 to build up the drill pipe. With an additional lifting of the leading rod 9 by the winch, a working space is formed between the rotator 6 and the pipe holder 8 mounted on the ground, which allows the use of a drill pipe, the length of which is twice the stroke of the rotator. Thus, the use of standard drill pipes (3 m) is ensured, while there is no need to increase the stroke of the rotator, which entails the use of more powerful guide masts, and hence an increase in metal consumption.

Therefore, the inventive self-propelled drilling rig provides a reduction in metal consumption and the ability to use standard drill pipes, twice the length of the stroke of the movable rotator.

Self-propelled hydraulic installation works as follows (see figure 2).

Pos. 1. The drill string is clamped by the pipe holder 8. The movable rotator 6 with the driving rod 9 in the upper position. A standard drill pipe (3 m) 12 is mounted on the drill string and screwed onto it manually. The movable rotator b with the driving rod 9 is lowered onto the drill string with the drill pipe 12 installed, screwing by the rotator occurs.

Pos. 2. The pipe holder 8 is unclenched, the cartridge 13 is clamped. Drilling takes place over the entire course of the rotator (approximately the L length of the drill pipe). The rotator moves down the lead 9.

Pos. Z. The tube holder 8 is clamped, the cartridge 13 is unclenched. The rise of the rotator 6 along the driving rod 9 to the gland 7 up.

Pos. 4. The pipe holder 8 is unclenched, the cartridge 13 is clamped. Drilling takes place along the entire length of the drill pipe (the remaining length of the drill pipe).

Pos. Z. The tube holder 8 is clamped, the cartridge 13 is clamped. Unscrewing the rotator 6 of the drive rod 9 from the drill pipe.

Pos. 6. The pipe holder 8 is clamped. The cartridge is clamped. Raising the driving rod 9 for the entire course of the rotator 6.

Pos. 7. The tube holder 8 is clamped, the cartridge is unclenched. Lifting the drive rod 9 with a winch 11.

Pos. 8. The tube holder 8 is clamped, the cartridge is clamped. The space has been prepared for the installation of the next standard drill pipe.

Pos. 9. The following drill pipe is installed on the drill string. Next, the operations are repeated, (see pos.1).

Thus, the proposed self-propelled hydroficated installation provides a reduction in metal consumption and the ability to use standard drill pipes, twice the length of the stroke of the movable rotator.
