The measuring device uses five three-winding IR – ZI025, 3I050, 3I075, 3I125, 3I200 probes. All probes consist of a common receiver winding, a single measuring path, and operate at the same frequency (100 kHz). The active and reactive components of the assumed conductivity for each probe are recorded simultaneously. The probes are housed inside a non-conducting glass-plastic container.

The device performs rapid analysis of the presence of hydrocarbons in the reservoir layers, including terrigenous sections. The induction logging method makes it possible to conduct research without galvanic contact between the probe and the environment.

The device consists of two sections. The upper electronics, housed in a steel housing, consist of a low-voltage source to measure the density of the electronic elements of the cavernamer and the shoe. The engine is installed in the section to open and close the levers. A removable cushion is installed in the lower section of the device to measure density and store the shoe. The potentiometer of the cavernamer placed in this section is to measure the distance between the upper areas of the pillows.

The Weber IN well inclinometer is designed to be operated as part of the Weberlog toolkit and determines the orientation of the well as a module.

Orientation is determined by three parameters: bending angle, azimuth and rotation of the device relative to the apical plane.

A three-axis accelerometer and a three-axis ferro-probe magnetometer were used as sensors in the inclinometer.

In addition, the inclinometer contains a detector that detects the natural gamma radiation of the layers, and the signals received from it improve the processing of inclinometric data.

The principle of measurement is the vector of the gravitations Ax, Ay and Az and Fx, Fy and Fz. software processing of initial data of the Earth’s magnetic field vectors and calculation of orientation.

Due to the sensitivity of the magnetometer installed in the device to the magnetic field, the body and internal parts of the device are made of non-magnetic materials.

In addition, the design of the inclinometer allows other devices to be connected from the top or bottom during the measurement.

The compensated neutron device performs density logging using a pair of neutron detectors, consisting of small and large distance detectors, to compensate for the irregular shapes of the well. The curve, calculated on the basis of data from small and large detectors, records existing lithological effects.

Small and large detectors of the compensated neutron device use LI: l type crystals measuring 4.45 cm X 5.08 cm. The information obtained through the crystals exists in the form of light pulses, which are transmitted to the FEU crystals, converted into electrical impulses, and amplified to the necessary fluidity to enable data processing. The signal is transmitted from the detector junction at a pulse amplitude of 400-500 mV with a pulse width of 5 ms.

The signal from the detector is transmitted to the discriminator at lower levels. The discriminator input pulses operate in the range of a few millivolts to a thousand millivolts and consist of a tunnel-type diode circuit. To ensure operation in a set of devices. Input levels from 400mV to 500mV are used.

The gamma logging module provides continuous measurement of exposure dose (EDG) exposure dose during gamma irradiation of existing natural radioactivity in mining rocks.

The module is used during drilling in oil and gas wells filled with any washing solution. The device is fed through a vein and is designed as a transient module.

During the development of the device, vibration-resistant, the latest model was used in scintillation detectors.

The device is up to 7000 meters long, can be operated alone with a single-core logging cable or in sets with Weber EK76, Weber 5 IK76 devices. The device can work with any digital logging station.

The Weber QR well device detects gamma radiation signals from oil wells. The device provides the necessary research materials for operation in drilling, exploration and production wells. The Weber QR device is placed on top of the assembly when operated in a set of well tools.

The standard operating mode of the Weber QR well device is to transmit pulse signals with a logging cable. When connected to a set of devices, it is desirable to transmit signals in the form of direct current. In this case, the multivibrator replaces the measuring module and signal frequencies by forming a linear module with direct current signals.

When transmitting overhead DC signals via cable, the Weber QR device is supplied with alternating current power via wires 4 and 6 from above. Thus, the telemetry adapter becomes a DICT CURRENT SIGNAL output.

Operated by a digital telemetry system with a ground logging station, the Rₓₒ dual side logging module operates and determines the coordinated Rₓₒ gamma radiation. The transmission system is designed to control a set of devices with seven wires. An additional advantage of the system is flawless data processing, eliminating external influences on the cable during logging.

The configuration used allows the digital transmitter to operate on 10 channels simultaneously. Additional ducts allow continuous control of the voltage at the end of the cable coupling to keep the supply condition in the well stable. Because it is sensitive to temperature changes, the detectors are housed in a Dewar container.
