Description

technical field [0001] The invention relates to an all-drill bit test hardware system and a test method thereof. Background technique [0002] In oil drilling, the drill bit is the main tool for breaking formation rocks, and it is an important means to increase the speed of penetration and reduce drilling costs in oil drilling engineering. In order to improve the rock-breaking efficiency of the drill bit and reduce the cost, it is necessary to design and select a drill bit suitable for the formation characteristics for different drilling formations. At present, the main methods of researching the rock-breaking efficiency of drill bits at home and abroad include field tests and laboratory tests. Field tests are the application of drill bits designed for different formations in the field, and then modify the design and reprocess, so that the development of a characteristic bit requires a period of time. Long and high cost; the main indoor test methods include single-tooth ver...
