JARI Through Bit Logging System, combined with high-speed cable communication, the downhole wireless communication, repeatedly hanging detachment and slim logging tool storage technology, solves logging problems of the horizontal wells and high angle wells with significant advantages of safety and timeliness, compared to the conventional drill pipe conveying, wet joint of connection and other horizontal well logging. The system has been applied in Daqing and Xinjiang oil fields and goes through the identification of the national Ministry of Science and Technology.

System Composition

• 57mm slim logging tools including conventional logging tools (acoustic, electric, and radioactive logging tools) and array induction imaging instruments.
• Hanger, battery sub, flexible sub and other through bit logging supporting tools.
• Logging surface system& software.
