Description

Technical Field

[0001] This utility model relates to the field of test adapter box technology, specifically a test adapter box for rotary guide M30 bus online testing. Background Technology

[0002] In the field of electronic testing in petroleum engineering, the electrical connection between downhole measurement equipment and surface systems faces the challenge of multi-standard compatibility. Existing technologies use customized adapter solutions, which require the combined use of SP3T coaxial connectors, Harting Han series heavy-duty connectors, and circular connectors, resulting in three major structural defects in the testing system.

[0003] 1. Standard fragmentation problem: The mixed connection of LCP control unit, pulser and M30 bus requires 3 independent adapters, with an overall volume of 2.5L.

[0004] 2. Test Intervention Obstacles: In the traditional solution, the generator output is directly connected to the downhole tool. When it is necessary to test the no-load characteristics of the M30 bus, the pulse generator connection must be disconnected, resulting in a test interruption time of ≥15 minutes.

[0005] 3. Lack of status monitoring: Existing connectors lack real-time diagnostic functions. When simulating downhole working conditions, a certain type of laboratory adapter has a contact failure rate as high as 23%, and it is impossible to quickly locate the fault channel through LED status indicators.
