Description

In the known devices for determining the curvature of boreholes with determining the deflection angle by marking the azgraf of the grid with the tip of a karashan sitting on the rod of the pilot, and determining the azimuth by photographing the position of the magnetic trelling, the inventor proposes on the other side of the moving belt with allogenic light on it. concentric circles for marking points on them with a pencil inserted into a manchee, put forward by a lever, periodically brought into action by a clockwork simultaneously with closure It indicates the current in the circuit and the photographic lamp positioned on the circuit of the magnetic needle on the photosensitive tape.

The drawing shows a vertical cut of the device.

A cylinder 11 is placed in a closed cylindrical shape of an I-box; in it, in a four-segment bearing 5 is fixed a tandem 4 with a special end attached with a spiral spring, which is inserted by a pencil b. The spinal spring is connected with the lever 7 with the clockwork, working simultaneously with the EK switch and the distributor 2 from the battery 12,

where pencil 6 is turned on, it is turned off from the chain and marks on a moving tape with concentric 5 dotted circles on it. The photosensitive paper is superimposed on the tape, on which, when marked on the ribbon with a pencil, the position of the magnetic arrow placed above the photosensitive paper of a compass 8, illuminated by an electric bulb .9 fed by current from a battery 12, is imprinted. The tape with photosensitive paper superimposed on it is wound on a roller 25 and pressed to it with a rubber roller 14; the free end of the tape, going under the compass, is put on the holes on the corresponding teeth of the wheel 3 and then is wound on the roller 10. On the axis of the gear wheel 8, which is set in rotation by the clock mechanism simultaneously by closing the chain, put the lever 7. In the cover and bottom of the box 1 the bolts are screwed on the nuts, with the clips, the ends of which are connected by hinges 18 with the rollers 15, which serve as guides during the descent and ascent of the device into the well. Between the lid and the bottom of the box and the sleeves of bolts placed coil springs 16, which are used to press the rollers 15 to the walls of the casing or well, with the upper

the upper cage bolt and the lower cage of the lower bolt are fixed to the bolts fixedly by means of through checks. The top bolt ends with a ring 17 to which a cable is attached to the well into the well.

To determine the curvature of the well, a device is lowered into it, the lowering of which must continue for three minutes, and at the desired depth keep it calmly for one minute, during which the distributor 2 closes the circuit. At the same time, the clockwork, the movement of the tape with the photosensitive paper and the pencil 6; at the same time, a lam of the point 9 of the compass 8 is ignited, and on the lower side of the ribbon, pencil 6 marks a point on one of the concentric circles, and on photosensitive paper, an imprint of the position of the magnetic arrow corresponding to the intended point is obtained in pencil. After a minute, the device is lowered into the well deeper or raised to the top, and you can make check marks during lifting. According to the obtained marked points on the tape and positions

fingerprints of a compass on light-emitting paper determines the location of the borehole in the vertical direction, as well as the azimuth "

The subject matter of the invention.

An instrument for determining the curvatures of boreholes, in which the determination of the deflection angle is made with a mark made on the grafling of the grid with the point on the rod of the ian cohort, and the definition of the azimuth by photographing a magnetic needle that differs from the bottom The sides of the moving sheet, on which the light of the stitching paper is laid, are applied to the end of the tricency circles for marking i points with the help of a pencil b, inserted in max 4, a lever 7 is used for extending, periodically WaWA mehank IOM TOI simultaneously with closure of the circuit, in which (p lamp included for the photographing position ma netic svetochuvstvitelns arrow on the tape.
