Problems solved by technology

The current traditional method is to collect various parameter information at the surface drilling rig, water pump and other equipment and mud circulation system, and it is also impossible to collect the hole bottom temperature and hole inclination parameters near the drill bit during the drilling process
Due to the differences in the depth of the borehole, the trajectory of the hole body, the structure of the borehole and the performance of the mud, the drilling parameters collected on the surface cannot reflect the real drilling parameters at the bottom of the hole, which often leads to misjudgment and then leads to accidents in the hole or affects drilling. Improve efficiency

Abstract

The invention discloses an automatic monitoring device for a geological core drilling parameter hole bottom. The device comprises a measuring short section body, a power module and a hole bottom drilling parameter measuring module. The upper end of the measuring short section body is connected with a drill rod, the lower end of the measuring short section body is connected with a drill bit, the interior of the measuring short section body is hollow, and a measuring groove is formed in the outer wall of the measuring short section body. The hole bottom drilling parameter measuring module is sealed in the measuring groove and comprises at least one of a hole inclination module, a rotating speed module, a temperature module, a drilling pressure and torque module, an outer annulus pressure module and an inner annulus pressure module. The hole inclination module, the rotating speed module, the temperature module, the drilling pressure and torque module, the outer annulus pressure module and the inner annulus pressure module are used for measuring the hole inclination, the rotating speed, the hole bottom temperature, the hole bottom drilling pressure and drilling torque, the outer annulus pressure and the inner annulus pressure respectively. The power module is used for at least providing electric energy for the hole bottom drilling parameter measuring module. The automatic monitoring device achieves measurement of real drilling parameters at the drill bit.

Description

technical field [0001] The invention relates to the field of geological core drilling, in particular to an automatic monitoring device for geological core drilling parameters at the bottom of a hole. Background technique [0002] During the drilling process of geological drilling, it is necessary to monitor parameters such as drilling pressure, speed, torque, annular flushing fluid pressure, etc., so as to monitor the drilling status at the bottom of the hole in time. The current traditional method is to collect various parameter information at the surface drilling rig, water pump and other equipment and the mud circulation system, and it is also impossible to collect the temperature of the bottom of the hole near the drill bit and the parameters of the hole inclination during the drilling process. Due to the differences in the depth of the borehole, the trajectory of the hole body, the structure of the borehole and the performance of the mud, the drilling parameters collect...
