Abstract

The invention relates to a rotary scraping single-tooth experimental device. The rotary scraping single-tooth experimental device includes an axial feed mechanism, a telescopic mechanism, an angle adjustment mechanism and a rock turning mechanism, and a PDC is installed on the angle adjustment mechanism. Single tooth, the angle adjustment mechanism is used to adjust the angle of the PDC single tooth, the axial feed mechanism drives the axial movement of the PDC single tooth, and the telescopic mechanism drives the radial movement of the PDC single tooth. component, the rotary component drives the rock fixture to rotate. The control system includes a PLC controller, and the power drive components in the axial feed mechanism, telescopic mechanism and rock turning mechanism are all associated with the PLC controller. The rotary scraping single-tooth experimental device can measure the influence of different parameters on PDC single-tooth rock breaking, and the adjustment accuracy of the angle is extremely high. In addition, the structure is simple and easy to use.

Description

technical field [0001] The invention relates to a rotary scraping and cutting single-tooth experimental device, which belongs to the technical field of simulated drilling experiments for oil and gas development. Background technique [0002] The exploitation of oil and natural gas is not easy. Oil and natural gas are mainly stored underground. To exploit oil and natural gas, drilling systems must be relied upon. The drill bit is the basic part of the drilling system, and the drill teeth on the drill bit are the basic part of the drill bit. Most drilling operations use the drill bit to drill the wellbore from the ground to the oil and natural gas storage. The difficult step is how to break the rock in the drilling path. In the ground, some rocks have high hardness, such as siliceous rocks, reaching a hardness of 7. If such rocks are encountered during drilling, the drill bit is easily worn or even broken, and other hardness rocks will also cause different degrees of wear on ...
