Description

technical field [0001] The invention relates to a testing device for a hydraulic power unit, in particular to a testing device for a hydraulic power unit of a rotary steerable tool, and belongs to the field of petroleum drilling engineering. Background technique [0002] The rotary steerable drilling system is an important drilling tool for complex structure wells such as horizontal wells, directional wells, and extended-reach wells. The rotary steerable drilling system reduces the underpressure phenomenon by rotating the casing or most of the casing, and the very short part does not rotate, so as to realize the construction of deeper and longer horizontal wells and directional wells. In recent years, the rotary steerable drilling system has gradually become a popular steerable drilling technology and one of the key technologies for efficient drilling. The hydraulic power unit in the rotary steerable drilling system is the bias mechanism of the steering system and the only ...

AI Technical Summary

Problems solved by technology

[0003] At present, the hydraulic power unit of the rotary steerable drilling system lacks system life and safety tests. The hydraulic power unit has an arc-shaped structure and is in a rotating state when working, so it is difficult to test

If the hydraulic power unit cannot be accurately tested, there will be no data support during use, and failure of high-pressure seals, hydraulic components, etc. will easily occur, resulting in failure of the hydraulic power unit, which will affect the failure of the entire rotary steerable drilling system, and affect the construction progress and effect.
