Instruments for measuring the azimuth of the curvature of boreholes, made in the form of a chamber lowered into the well, containing a light source suspended on a gimbal and a photocell connected to an electrical measuring circuit are already known. Also known are devices for measuring the azimuth of the curvature of wells, equipped with a magic L / C.

In the device described here, the measurement of the azimuth and curvature of the drilled wells, in contrast to izzestzgyh devices, is attached to a screen mounted on a magnetic arrow with a radial and, like that gap, located between the light source and the photocell, the photosensitivity and surface strength of which is graped spirals.

FIG. I shows the device in longitudinal section; in fig. 2 is the same section on YES; on f; g. 3-photoe.psmscht device.

The device consists of a brass chamber 7, which is connected tightly to the apparatus, the angle of rotation of which is necessary to determine. In the cover of the chamber, the cap 2 is mounted with a gimbal, in which light source 3 is enclosed, a photocell 4 and a magnetic needle 5 with a screen: M 6. The upper part of the cap 2 has a spherical shape and is provided with holes for cardan supports.

The cap is hung on two-cores, cc;) scheduling in the cardan's ring 8, which, in turn, is suspended on two cores, wipcheped in 1; after the suspension 9. The hook of the suspension 9 is inserted into the recess of the chamber lid and fixed in it clip) th cat. m on the thread. Due to the presence of two pairs of cores perpendicular to the centerline of one pair to the centerline, the other axis of the cap is always installed vertically when the instrument is tilted in any direction. Inside the cap is placed an electric lamp 5, screwed on the thread in the cap as in the cartridge, which gives

JV 60920- - 2 - contact with the earth. The second contact of the bulb is connected to a flexible conductor connected by a second end to an input rod. The cap 2 from the spherical head at the top transforms into a cone in the middle part and ends at the bottom with a cylindrical part. Below in kolpzchsk enters photocell 4 in bakelite frame. The photocell has the form of a round disk. The needle 10 is fastened in the center of the photocell plate. The needle is supported by a magnetic needle 5. Magnetic arrow. A square bar is made of a material with high magnetic properties (steel). Into the hole of the bar is inserted in the brass rim of onor from solid agate stone. From the bottom to the magnetic needle, a single mini screen 6 is placed with a narrow radial gap 12 (Fig. 3).

The photocell 4 has a sensitized pszernogt 13 limited by the circumference and the helix (Fig. 4). The photocell is oriented on the cover. The magnetic arrow is always set in the direction of NS, and therefore the slot 12 of the screen 6 is also always in the same position relative to the countries of the world. In different relative positions of the photocell 4 and the screen 6 clicks) 12 opens the light flux sensitive surface 13 of different area. The relative rotation angle is determined by the magnitude of the electromotive force excited in the photocell.

The photoelectric 4 electrodes connect one to the ground and the other to

All parts of the device are made of non-magnetic material (except magnetic needle). The instrument must be removed at least 0.5 meters from the magnetic bodies.
