The hydraulic-magnetic driving borehole cleaning tool magnetic torque testapparatus comprises a magnetic driving assembly, a brake assembly, a pressure measuring assembly, a front supporting plate, a front supporting plate, a rear supporting plate and an experiment table, wherein the magnetic driving assembly is installed between the front supporting plate and the rear supporting plate by virtue of a rotating shaft; the magnetic driving assembly comprises an inner magnetic shaft and an outer magnetic shaft, the two magnetic shafts are coaxially arranged, the inner magnetic shaft is integrally formed by a rotating cylinder and a rotating shaft, the outer wall of therotating cylinder is uniformly provided with outer bar-shaped key slots along the axial direction, an inner permanent magnet is embedded into the outer bar-shaped key slot, and two ends of the rotating cylinder are respectively provided with an inner magnet protection sleeve; the front end of the rotating shaft is provided with a rotating round bar; and the inner wall of the outer magnetic shaft is uniformly provided with inner bar-shaped key slots along the axial direction, the outer permanent is embedded into the inner bar-shaped key slot, and two ends of the outer permanent are respectivelyprovided with an outer magnet protection sleeve. By adopting the hydraulic-magnetic driving borehole cleaning tool magnetic torque test apparatus and test method, the torque test method is simplified, and the torque measuring precision can be improved.

Description

Technical field: [0001] The present invention relates to a novel hydraulic-magnetic transmission wellbore cleaning tool in the drilling process of oil and gas wells, in particular to a hydraulic-magnetic transmission wellbore cleaning tool magnetic torque testing device and testing method. Background technique: [0002] At present, well types such as high-inclination wells, horizontal wells, and extended-reach wells are often used in offshore oil and gas exploitation to increase the drainage area of ​​the wellbore and maximize the production of a single well. Due to the existence of the build-up section (the curved well section whose inclination angle increases from 0° to 90°) and the horizontal well section in these well types, the cuttings are not easily carried out of the wellbore by the drilling fluid under the action of the gravity component, and cuttings appear. Phenomenon of accumulation, forming a bed of cuttings. If the thickness of the sedimentary cuttings bed in ...
