Data acquiring system for well drill bit and acquiring recorder

Abstract

The invention belongs to the technical field of measuring of mechanical environments of well drill bits, and specifically relates to a data acquiring system for a well drill bit, an application method of the system and an acquiring recorder. The system comprises the acquiring recorder, a testing computer, a power supply system and a signal system; the acquiring recorder is used for converting a sensor signal and storing and sending the result data; the testing computer is used for setting the parameters of the acquiring recorder and acquiring data from the acquiring recorder; the power supply system is used for supplying power to the acquiring recorder; the signal system is used for providing a signal to the acquiring recorder; when in use, the debugging and calibration are carried out before mounting; the acquiring recorder comprises a multi-channel signal adapting module, an analog-digital converter, a storing unit, a power managing module, and a built-in communication management unit type control CPU. The system has the beneficial effects that the acquiring recorder is small, the reliability is improved, the application pertinence is improved, and the void in the measuring field fills.

Description

technical field [0001] The invention belongs to the technical field of drilling bit mechanical environment measurement, and in particular relates to a drilling bit data acquisition system. Background technique [0002] The drilling bit data acquisition system is installed in the drilling bit and is mainly used for measuring the mechanical environment during the working process of the drilling bit. Due to the harsh working environment of the drilling bit, it not only needs high-speed rotation, but also has high vibration, high impact and high temperature environment, which puts forward strict requirements on the environmental adaptability of the mechanical environment measurement equipment of the drilling bit. Secondly, due to the limited space of the drilling bit itself, the installation space provided for sensors and measuring equipment is very limited without affecting the structural strength of the drill bit itself. Furthermore, the working life of a drill bit is long, o...

Secondly, due to the limited space of the drilling bit itself, the installation space provided for sensors and measuring equipment is very limited without affecting the structural strength of the bit itself.

Furthermore, the working life of a drill bit is long, often several days, and the rotation of the drill bit makes power supply a difficult problem
