描述:
Downhole telemetry systems GKS with a hydraulic communication channel are designed for operational control of the drilling path of directional and horizontal oil and gas wells by continuously measuring the installation angle of the deflector, azimuth, zenith angle and natural radiation of gamma rocks.
概观:

GKS telemetry systems allow measurements of the following parameters during drilling:

  • Zenith angle
  • Azimuth angle
  • Deflector Position
  • Rocks gamma radiation
  • Bottom temperature
  • Generator revolutions
  • Vibration
  • The total magnetic field of the Earth
  • The total vector of the Earth's gravitational field

Permneftemashremont JSC produces GKS telemetry systems with a hydraulic communication channel of the following standard sizes:

203, 178, 108 mm.

Features

GKS telemetry systems have the following features:

  • Allow drilling with constant rotation of the drill string by the rotor,
  • They are batteryless, i.e. use a downhole generator operating from the movement of flushing fluid as a power source,
  • The design of the generator does not have mechanical seals, the oil is not consumed during the operation of the generator, there is no need to control the level and add oil in the drilling environment,
  • They have no operational limitations related to the depth and geological conditions of the wells.

Principle of operation

  • GKS telemetry system consists of a downhole tool, which is installed in the layout of the bottom of the drill string above the hydraulic downhole motor, and ground equipment,
  • The downhole tool consists of a pulsator, a downhole measuring unit and a generator. In the process of drilling, the downhole tool measures the navigation and geophysical parameters and, using a pulsator, converts them into pressure pulses that propagate through the fluid barrel in the drilling tool and are received by the pressure sensor on the manifold.
  • Ground equipment consists of a pressure sensor, a receiving device (interface device), a computer station, weight and depth sensors, and a driller monitor. On the surface of the Earth, the signal received by the pressure sensor on the manifold is sent to the receiving device, where it is amplified, filtered and decoded. The decoded information is sent to the driller’s monitor and to the operator’s computer and stored in memory in any convenient format for work.
  • The software package used to process the readings of the telemetry system performs information exchange, editing, linking measurement data to depth, visualization on the monitor in digital and graphic form.
