Description

Technical Field

[0001] The invention relates to a torsion impact tool test system in the field of downhole power drilling tool test systems. Background Art

[0002] Torsional impact tools are a type of downhole impact power drilling tools. They were developed by the Drilling Technology Research Institute of Sinopec Shengli Petroleum Engineering Co., Ltd. in China in 2010. As the performance of this series of tools needs to be verified step by step, the existing downhole tool experiment and test system cannot meet the test requirements of torsional impact performance parameters. Therefore, a test system is specially developed for torsional impact tools to gradually realize the serialization of SL torsional impact products.

[0003] At present, the downhole tool test system can only test pressure and flow rate. In actual work, the torsion impact tool has no displacement relative to the drill bit, so it is necessary to simulate the frequency and force of the circumferential impact applied by the torsion impact tool to the drilled formation through the PDC drill bit. However, the existing downhole tool test system cannot meet the requirements of real-time and accurate measurement of the performance parameters of the torsion impact tool under different media and different flow rates, including flow rate, pressure drop, impact frequency, impact force and vibration.
