Purpose of the development: Designed for continuous monitoring and recording of process parameters of the process of drilling for the purpose of operational control and optimal drilling, trouble-free wiring directional wells.

Recommended application field: Use cases: 1. Provision of directional and horizontal sections of oil and gas wells industrial hydraulic motors. 2. Ensuring the project well profile, load optimization on the bit, evaluation of the degree of wear. 3. Correct design profile on real geophysical data that is obtained during drilling (EMWD mode). 4. The use of electromagnetic communication channel cable line; 5. Use in normal mode, the logging tool (for example, high-precision inclinometer) in the open hole, or inclinometer mode, discharged (LWD mode).

Technical characteristic: Zenith angle from 0 ° - 180 ° ± 0.1 °. The azimuth angle from 0 ° - 360 ° ± 0.5 °. Sighting angle from 0 ° - 360 ° ± 0.5 °. Vibration Level 0 - 50g ± 0.1g. Axial load 0 - 25ts ± 0.1ts. Torque 0 - 1000kgs · m · m ± 50kgs. The electrical resistivity of 0.2 - 100 ohm · m ± 10%. Gamma radiation 2 - 50mkR / hr ± 10%. The temperature of 10 ° - 90 ° C ± 0.5 ° C. Max. rpm electric turbines 400 - 600 rev / min ± 10%. Consistent signal reception without repeater with a conventional whip antenna - at depths of up to 2.5-3.0 km. Good reception from great depths (4.0 - 4.5 km) by using a downhole repeater.

Advantages over analogues: Horizontal wells allow an increase in oil and gas production from 2 to 10 times compared with the vertical wells. It is shown that the profile of the well may be determined in real time without stopping to conduct ordinary control measurements inclinometers.

The development stage readiness: Tested experimental exploitation order

Technical and economic effect: Estimated value of the telemetry system with information processing facilities and its operation and maintenance costs amount to about 120 thousand. euros for the complex, several times less than the cost of construction and commissioning of at least one vertical well.

Description of the development:
()
Solenoid link provides transmission of information when the mud pumps are not running, or when drilling is carried out by blowing air or drilling fluid is used when the oil-based. The composition of the lethal TV system: The wellbore portion (shuttle dipole) and the surface portion (antenna, transceiver, software and computer system) interconnected electro potentially cable-free communication channel. The non-volatile boat taken by physical sensors, microprocessor module, power equipment (batteries) and a transceiver unit. The basic model of lethal TeleSystems has a length of 6000 mm and a diameter of 172 mm, it allows for a well with a minimum radius of action in the cavity 75 - 100 m, the drill provides a maximum rate of 4-5 degrees of curvature set at 10 m.
