Testing method based on testing hardware system of full bit test

Abstract

The invention discloses a testing method based on a testing hardware system of a full bit test. The testing method includes the following steps: (a), first testing the bit pressure, the displacement and the torque of a bit through a pressure sensor, a displacement sensor and a torque sensor; (b), meanwhile testing the rotation speed of a swivel plate and the rotation speed of a cone through a swivel plate rotation speed sensor and a cone rotation speed sensor; (c), amplifying signals tested in the steps (a) and (b) through an amplifier, and collecting the signals through a data acquisition card; and (d), inputting the signals into a computer for analysis and processing. The testing method based on the testing hardware system of the full bit test can complete the test of bit performance diameters successfully, the test process time is short, the automatic degree is high, the extended functions are wide and the production cost is low.

Description

technical field [0001] The invention relates to a testing method based on a full drill bit test testing hardware 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-t...

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
