SU16095A1 - Apparatus for detecting borehole deviations - Google Patents

Description

The deviation of boreholes is meant to be determined by the proposed apparatus, when mediating two balls, included in an electric stump with a galvanometer and immersed in a conductor, the first current, when

than by the divergence of the balls when the whole apparatus deviates, the magnitude of the borehole deviation is judged. : In the drawing of FIG. 1, the apparatus is shown in longitudinal section; FIG. 2 and 3 are the connections of the apparatus.

The device consists of vessel 1, made of insulating material and inserted into frame 2. Inside the vessel, on the tips, the lever 10 is rotated by the counterweight. G one rtorona to the lever. a rod is attached, 4 with a flange 7. The stem of the VU connected to another conductor and also equipped with niapH 8, movably secured at the points x iH may deviate in the plane of the hatch 10. Thus, the distance between the balloons depends on the angle of inclination of the device. As this distance changes, the resistance of the electrolyte in which the balls are immersed changes. The balls 7 and 8 by means of insulated conductors through u 3 are connected by a "rope, on which the apparatus is lowered into

"Well at a certain depth, include

in the circuit of the current n, notice the slugging of the galvanometer's heated stick. Then, turn off the device a, (Fig. 2), which is in the well, and turn on an identical device 5, which is on the surface instead, giving it an inclination angle that the galvanometer. gave the old show. This angle of inclination will be the angle of curvature of the well at a given depth. The rheostat is used so that the observation can always be entered in, within the scope of the reading of the galvanometer.

According to FIG. In place of the upper apparatus, a milliammeter is included, previously graded in degrees of deflection angles. At the same time, corrections (temperature, etc.) should be introduced in the instrument readings.

The subject of the patent. .

An apparatus for determining the deviation of boreholes, lowered onto a rope, having inside two isolated gaps, forming a circuit with a galvanometer connected to it, characterized by the use of fluid in a connected vessel 1 with conductive fluid. one conductor of the rod 4 with the ball 7 rigidly fixed on the rotating on

the tips of the lever 10 with a counterweight, and a movably mounted on the tips of the rod 5 connected to another conductor, also equipped with a ball 8 at the end, by the deviation of which from the ball 7 judging the deviation of the borehole; deviation, arrows galvanometer corresponding to the divergence of the balls.
