Downhole telemetry system with hydraulic communication channel LHE630N

 

Features and benefits.

  • Wireless/Wired communication system equipment on the ground.

  • Power supply modules downhole TeleSystems is carried out by means of a block of lithium battery.

  • The design of bottom-hole telemetry MWD allows the connection of additional modules of gamma-logging, the unit of the lithium batteries.

 

Operating conditions.

  • The sand content in the solution is 1.0 %.

  • The allowable diameter of the solid fraction in solution is 2 mm.

  • The viscosity of the drilling mud ≤140.0 sec.

  • The drilling mud density ≤1.7 g/cm3
