    An arrangement for guiding a drill crown or bit (8) (FIG. 4) in a given drilling path comprises an outer guide tube (7) in which a shaft (6) is rotatably arranged. The shaft is driven by a drive means (5) connected to one end of the shaft, while the bit (8) is mounted for rotation on and guided by the other end of said shaft. The axis of rotation (9) of the bit forms an angle ( alpha ) with the central axis (10) of the guide tube, said tube being non-rotatably, but axially displaceably connected to an axially feeding device through intermediate means (11).

    (5) DEVICE FOR DRILLING DIRECTED WELLS
    one
    The invention relates to drilling equipment, devices for drilling directional wells in hard rock.
    A device for drilling directional wells is known, consisting of a chisel, a non-rotating guide pipe, a flexible shaft connected in the upper part with driving means, and in the lower part with a chisel C13.
    The specified device has a complex structure and limited drilling.
    The closest technical solution to the invention is a device for drilling directional squalls, including a bit or bit; a non-rotating guide tube, located in its internal cavity, is a flexible shaft, on the outer surface of which there are supports, two of which are at the ends of the flexible shaft, and one, eccentric, between them, the flexible shaft is connected in the upper part with driving means, and at the bottom with a chrome chuck 2.
    The disadvantage of this device
    5 is that during the drilling of hard rocks, the radial forces acting on the drill bit cause deformation of the flexible drive shaft, which in turn makes it difficult to guide the well along a predetermined trajectory.
    The purpose of the invention is to improve the accuracy of wiring curved sections of the trunk when drilling hard rock. This goal is achieved by
    16 that the supports mounted at the ends of the flexible shaft are placed coaxially with the guide tube, and the bit or bit is connected through the lower support of the flexible shaft with the guide tube.
    20 In FIG. 1 schematically shows a device for drilling directional wells; in fig. 2 - wellbore, the trajectory of which deviated from the straight line; in fig. 3 device for

    25 of directional wells drilled down into a curved well; in FIG. C a curved well. The device consists of a guide tube composed of lower 1 and upper tubes.

    2. In the inner cavity of these pipes there is a flexible shaft 3 connected in the lower part with a crown k through the sleeve 5 and in the upper part with drill pipes 6 through the sleeve 7. Bearings, two of which are ball bearings 8 and 9) mounted along the ends of the flexible shaft, coaxially with the guide tube and one eccentric sliding bearing 10 in the interval between them. The crown is connected to the lower pipe 1 through the sleeve 5 and the bearing 8, while the axis of rotation of the crown 11 forms an angle A with the central axis of the guide pipe 12. Angle d is 0.11, 5 °, and other values are possible. The upper end of the Uruba rail is fixed and in its present form there is a attachment of the driving means 13 to the feed. When drilling with conventional shells, the trajectory of the borehole 1 may deviate from the straight design line 15 (see Fig. 2). The device is lowered into a curved well, orienting its plane of action, passing through axes 11 and 12, relative to the curvature of the wellbore and starting to drill (see Fig. 3. The axis of rotation of the crown is constantly supported in a given direction with Fig. k). The guide tube is inserted either onto the surface or has means in contact with the wall of the trunk preventing it from rotating. After drilling the part H of the trunk, the design direction 15 is done and further wiring work I I is carried out with the usual Projectiles with directional bore trajectory deviating from the straight line when drilling section 1A, again use the device for drilling directional wells. the borehole and thus increases the efficiency of drilling operations. The invention Apparatus for drilling directional wells, including a bit or crown, non-rotating guide pipe, located in its interior The cavity of the flexible shaft, on the outer surface of which there are supports, two of which are at the end of the flexible shaft, and one is eccentric, in the interval between them, the flexible shaft is connected in the upper part with driving means, and in the lower part with a chisel or crown, characterized in that, in order to increase the accuracy of wiring curved sections of the barrel when drilling hard rocks, the supports installed at the ends of the flexible shaft are placed coaxially with the guide tube, and the bit or crown (through the lower support of the flexible shaft with the guide tube).
