Description

technical field [0001] The invention relates to a performance testing experimental device, in particular to a hydraulic oscillator performance testing experimental device simulating different drill pressure working conditions. Background technique [0002] During the drilling process of horizontal wells, the drilling tool will produce large friction and back pressure in the well section with large borehole curvature, or in the too long horizontal section, which cannot effectively apply the pressure on bit. Large frictional resistance and supporting pressure not only seriously affect the ROP of horizontal wells, but also easily cause complex downhole accidents such as sticking. In order to prevent the occurrence of the above-mentioned problems, hydraulic oscillators are usually installed on the drilling tools during the current horizontal well drilling process. The hydraulic oscillator changes the static friction of the drilling tool downhole into dynamic friction through pr...
