Description

In the apparatus related to the known devices for determining the curvature of the drills, scaling the electrically conductive liquid by measuring the curvature by closing the electrical circuit, turning on one of the contacts located around the inner circumference of the apparatus, and transferring signals to the surface when the circuit is closed under the influence of a change in the level of the electrically conducting fluid , the inventor places in the upper part of the cylindrical apparatus a system of insulated wires: horizontal annular, each connected separately by thin wires with zolirovannym wire cable connected with the other end gradusopokazatelem and cartridges for bulbs and vertical wires Zholobov separately placed in the cylinder, the lower ends of which terminate at a lower horizontal ring. The upper ends of the vertical electric wires are connected to the cable connected to the electric compass cartridges, powered as well as the temperature indicator from the current source connected by a wire to an electrically conductive liquid.

The schematic drawing shows the proposed apparatus with its attachment to a temperature indicator and a compass.

The proposed apparatus consists of a non-conductive hollow vertical ribbed cylinder A, the lower end of which is provided with a conical bottom and a and the vertical end is closed with a conical cover b. On the outer side, cylinder A. is provided with four ears, two at the top and bottom, serving to attach the cylinder to the shank. An electrically conducting fluid d is poured into a cylinder to a certain level, and a system is installed above it, electrical conductors from horizontal rings e and vertical-g; The first electric wires are located on the inner side of the cylinder in a strictly defined order, so that each ring e, when tilted, shows a deviation of 1 °. The number of rings must be at least sixty five to obtain a measurement of the deflection angle of 65-70 °. Rings e are connected by thin insulated wires 3, twisted into one rope, with a telephone cable s consisting of 65-70 insulated wires. The cable length and corresponds to the depth of the measured well. The other end of each wire 3 is connected to a temperature indicator And, on which for each deviation of 1 ° a cartridge is installed for an electric bulb and connected to a current source K. Vertical wires are placed in each groove of cylinder A every 5 ° around the circumference, and their lower ends are set at the level of the lower horizontal colled e, so that the liquid g is simultaneously / in contact with the vertical wires and the lower ring g; The upper ends of the wires are connected: they are not connected to the wires of the telephone cable Y /, the other ends of the wires of which are connected to the cartridges H for jtia bulbs: electrically open A, from which all the bulbs go to the source K. K Liquid is connected to the source. " PM of the current To the wire n passing through the lower end of the cylinder A, the degree of deviation I and the compass M are installed on the free surface. The operation of the apparatus is as follows. An apparatus on the measured rod or anathe is lowered into the borehole, and when the direction changes, the apparatus changes its position in it, as a result of which the fluid d is in contact with the corresponding inclination of both the horizontal and vertical wires corresponding to the inclination ; And (tilt) and on the I OM pass M (azimuth) rejected.

According to the inventor, on the basis of the indications of the degree of inclination and compass deviation possible,. Do not remove the device from the borehole, make a diagram of the direction of the recessed well.

The subject matter of the invention.

A device for determining the curvature of burrow squas; 11n with application for closing the current: Electro; (Noah fluid, characterized in that in the upper part of the cylinder is placed a system of mutually insulated wires: horizontal ring e, each connected separately with thin wires h to the insulated wires of the cable and the other end of which is centered with the degree indicator on which the cartridges K are placed by the number of electrical wires , and vertical wires, placed in each chute of cylinder A, the lower end of which is at a height of lower; it has an electric ring e, and the upper ends of the vertical wires jristoed to the isolate ovannym cable wire A, and summed to cartridges elektrokompasa M fed, shock, as well as gradusopokazatel // K from electricity source connected to the electrically conductive fluid conductor n.
