Abstract

The invention relates to a rotary scraping single-tooth experimental device, the rotary scraping single-tooth experimental device comprises an axial feeding mechanism, a telescoping mechanism, an angle adjusting mechanism and a rock slewing mechanism, the angle adjusting mechanism is provided with a PDC single tooth, the angle adjusting mechanism is used for adjusting the angle of the PDC single tooth, the axial feeding mechanism drives the axial movement of the PDC single tooth, and the rock slewing mechanism drives the axial movement of the PDC single tooth. The telescopic mechanism drives the PDC single tooth to move in the radial direction, the rock rotating mechanism comprises a rock clamp and a rotating assembly, and the rotating assembly drives the rock clamp to rotate. The control system comprises a PLC (Programmable Logic Controller); and power driving parts in the axial feeding mechanism, the telescopic mechanism and the rock slewing mechanism are all associated with the PLC. The rotary scraping and cutting single-tooth experimental device can measure the influence of different parameters on PDC single-tooth rock breaking, the angle adjusting precision is extremely high, and in addition, the rotary scraping and cutting single-tooth experimental device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a rotary scraping single-tooth experimental device, which belongs to the technical field of oil and gas development simulation drilling experiments. Background technique [0002] The extraction of oil and natural gas is not easy. Oil and natural gas are mainly stored underground. To extract oil and natural gas, you must rely on the drilling system. The drill bit is the basic component of the drilling system, and the drill teeth on the drill bit are the basic components of the drill bit. Most drilling operations use the drill bit to drill the wellbore from the ground to the oil and gas storage. This process, the most The difficult step is how to break the rock in the drilling path. In the ground, some rocks have very high hardness, such as siliceous rock, which reaches a hardness of 7. If such rocks are encountered during drilling, the drill bit is easily worn or even broken. Rocks of other hardness will also cause different de...
