The testing experiment device comprises long straight steel pipes, an installing disk A, an installing disk B, and an installing disk C. The central positions of the installing disk A, the installing disk B, and the installing disk C are provided with assembling holes. The periphery of each disk on the outer side of the assembling hole is uniformly provided with steel pipe holes. The installing disk A, the installing disk B, and the installing disk C are connected with each other through long straight steel pipes passing through the steel pipe holes. The testing experiment device is simple in structure, and convenient in use. The device effectively solves problems of applying drilling pressure on the hydroscillator in an existing laboratory. Compared with carrying out experiments by using a hydraulic analog device, the device is simple and feasible, and is characterized by effectively controlling cost. The device provides important experiment basis for structure optimization of the hydroscillator and optimization of parameters of field service.

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...

During the development of hydraulic oscillators, it is usually necessary to test their performance under different WOB conditions. Most of the existing tests use hydraulic simulation devices for testing. Most hydraulic simulation devices have complex structures and errors in test data. Insufficient, therefore, it is necessary to develop a simple structure, can design and simulate different weight-on-bit working conditions, test key parameters such as tool frequency, displacement and vibration impact force, so as to analyze the parameters of hydraulic oscillator structure optimization and field service through test data analysis The optimization of the experimental device that provides important experimental basis
