SU106949A1 - Device for measuring the azimuth and angle of boreholes - Google Patents

Description

In exploration drilling, which is one of the main types of mineral exploration, accurate knowledge of the azimuth and angle of inclination of boreholes is a prerequisite for conducting the drilling process with the least technical complications, as well as for correctly determining the true power of minerals.

The proposed device, designed to solve these problems, refers to a known type of device that provides the ability to measure the azimuth and angle of inclination of boreholes with the help of two pad systems equipped with points for fixing their position on the paper diagram by puncturing it with periodic pinching diagrams to the points made by the core of an electromagnet, the winding of which is powered by electrical impulses;

The peculiarity of the proposed device is that, with the complete provision of multiple recording of the positions of waders on the below diagrams, the needle holder is securely fixed on the master with the possibility of sequential movement along the radius of the diagram with the help of a gear rack to the ratchet mechanism that engages when pressing the electromagnet core before each puncture of the chart.

FIG. 1 depicts a general view of the proposed device; FIG. 2 - the node, denoted by the letter A in FIG. one; FIG. 3 is a circuit diagram of the device.

A rod 2 is fastened to the string of drill pipes / (fig. 1), on which there is a cut-out under the plug to zero forming risks. The rod is rigidly connected to the sealing plug 3, the spherical surface of which is pressed by the nut 4 to the conical undercut of the device body. To the plug 3 there are rigidly Kpqpits cylinder 5 with two bushings 6, in which there are ballons shippiki 7, frames 8 of the node, measuring the slope of the well and placed in cylinder 5.

The paper disk 16 is mounted on the back side of the frame. There are also locks of the initial (zero) position of the paper. Before starting the measurements, the master’s carriage with the needle is manually pushed in the lowest position. common arresting frame of the power pluy / 5, United through the rack 19, the bar 20 and the rod 21 with the wheel 22 electromagnet 23.

The armature 22 of the electromagnet 23 is also connected to the plate 24 and with the rods 25, to which the arresting cylinder 26 is attached. On the rods 25 there are coil springs, which during the course of the cortex are compressed and store the energy necessary for arresting the moving elements of the device. A cylinder 27 is attached to the body of the electromagnet 23, and to it a cylinder 2L, of which the details of the element accommodate, measure its first azimuth.

The azimuth measurement is also based on the principle of using a gravitational zero ground. The sensitive element is a horizontal horizon 29, fixed on axis 30, and is broken; aypus is free at the moment of measurement in podchnik 31. From one end, the horizontal 29 has a load 32, on the other end, a ratchet lever 33 with a toothed rack:} of the carriage 34, which has the lyvibi 35 holder, which is itself. . The paper disk 36 is pressed by the table 37 to the protrusion of the cylinder 2, on which there is a clamp zero. generated in the form of risks. The mechanism for moving the carriage-needle holder is shown separately in FIG. 2 (node A). The same 10 mechanism has the same mechanism.

A cylinder 39 is mounted to the hub 38 of the cylinder 28, in which a relay switching circuit is mounted, consisting of two relays 40a and 406, an electrolytic capacitor 41, a clock switch 40 with a switch 43 in rubber damping 44. Even lower, the frame 45 of the power supply unit is attached dry elements 46. The case is closed from the bottom by a stopper 47 with a tip 48. instead of which a boyle pipe can be screwed.

Before starting work, new paper discs 36 and 16 are inserted, movable carriages are installed in the initial position, the duration of the time interval between successive measurements (5, 10, 15 or 20 minutes) is set on the switch 43, the hands of the clock switch 42 are set

so that the time before the start of the measurement is sufficient for the descent of the Ustronstape to a predetermined depth. Thereafter, the device is sealed and descent and a well is made. At the right time, the clock running synchronously with the clock mechanism of the switch 42 and at the right time (at the right depth) descends stops for 1.5-2 minutes to measure at a given point, etc., until the end of the measurements.

G1ri1niialnaya electrical circuit of the device shown in Fig, 3,

When the contact is closed, the clock switch 42 closes the relay circuit 40a, which supplies the electromagnet / 5 of the frame 5 of the measuring angle assembly and closes the circuit of the relay 406, which supplies power to the electromagnet 23.

After breaking the value of the relay 40a by the switch 42, the electromagnet 15 is deprived first, and then the electromagnet 23, since the capacitor 41, switched on, locks the relay 406, supports the excitation of the electromagnet 23. This is done so that and then there was a general arrest, which eliminates the possibility of knocking down the tattern and the vyèche: enn error;

Corners are counted after the instrument is lifted and paper discs are removed on a special protractor with a division value not lower than 0.1 °. Disks are laid on the protractor board ;, the corners formed by the initial (zero) mark and puncture points are centered and then passed all decreasing radii. The design of the protractor is elementary simple and therefore its description is not given here.
