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 ...
