Problems solved by technology

[0007] The functions of these drill bit test equipment are not perfect, and the control of the entire test process is realized by manual operation of the operation console equipped with various controls. , poor flexibility, large limitations of extended functions, susceptible to external interference, acquisition signals contain a lot of noise and high hardware costs, etc.
With the increase of oil drilling depth and the complexity of formation rocks, the research work of designing and developing drill bits according to the characteristics of different formation rocks is more urgent, and the importance of drill bit test and testing is more prominent. To the requirements of the high performance drill pilot test

Abstract

The invention discloses a test system of full gauge drilling bit rock breaking. The test system of the full gauge drilling bit rock breaking is mainly formed by a drilling bit test rack (1), a lower turnplate (2), a measuring connector (3) and a displacement sensor (4), wherein the lower turnplate (2) is arranged below the drilling bit test rack (1), the measuring connector (3) is installed on the drilling bit test rack (1), the drilling bit test rack (1) is connected with a driving device, and the measuring connector (3) and the displacement sensor (4) are both connected with an identical measuring and control device. The rate of penetration and the broken shaft bottom of different rock breaking of the drilling bit under a certain parameter condition are mainly detected, and characteristics of the rock breaking with the drilling bit can be reflected simply and really.

Description

technical field [0001] The invention relates to a full drill bit rock breaking test system. 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 vertical press-in test, ...
