描述:
The KORVET bottom-hole telesystem with a hydraulic communication channel is designed for measurements during drilling in order to control the direction of drilling and lithological breakdown of the well section.
概观:

The telesystem includes

  • bottom hole
  • ground panel
  • scorer board

Main advantages

1. The CORVET system uses a reliable rotational pulsator with a positive pressure pulse. This type of pulsator has been available for over 7 years. At the moment, about a thousand pulsators have been released that work around the world. The design of the pulsator virtually eliminates blocking or jamming of the valve. A positive impulse rotary pulsator is one of the most resistant to mud additives to combat absorption.

2. The CORVET design makes it possible to use the same borehole assembly in arrangements of various diameters. This allows a more rational use of the existing equipment park. The KORVET design provides for an arbitrary sequence of downhole modules in the system, which allows the installation of battery and instrument modules depending on conditions and tasks.

3. The supplier provides personnel training and equipment supply for the organization of service centers at the Customer for regular maintenance of systems. Equipment repair and complex maintenance are carried out in the manufacturer's service center in Tyumen. The service center has a warehouse of spare parts and consumables.

4. The cost of the system is 30-50% lower than that of foreign counterparts.

terms of Use

The KORVET system provides measurements at upper environmental values in the range of research up to 120 ° С at hydrostatic pressure up to 80 MPa.

Diameters

The outer diameters of the KORVET downhole telesystem : 89 mm (3.5``), 120 mm (4.75 ''), 171 mm (6.75 '') and above.

Outside diameter of a downhole tool with a pulsator: 48 mm.

In systems of different diameters, the same downhole tool and a pulsator with a diameter of 48 mm are used.
To install a device with a pulsator in a system of a different diameter, it is necessary to exchange only the following elements for the corresponding ones:

  • non-magnetic pipe with pulsator housing
  • downhole tool centralizer rubber
  • pulsator rotary valve.

Mud flow rate
