Abstract

The invention discloses a drilling parameter detector. The detector comprises a mainframe device, a sensing head device and an impact device. The mainframe device comprises a data processing module, a microprocessor and a display module. The sensing head device comprises a stress sensor (such as an acceleration transducer and the like) and an inertial navigation element. The impact device is an impact generator (such as a wooden hand hammer and the like) capable of generating high impact energy. The drilling parameter detector disclosed by the invention has a compact structure and is convenient to use. A required signal can be conveniently acquired by using the stress sensor and the inertial navigation element, so that the measurement and calculation of the depth of a drilled hole and the opening three-dimensional space stereoscopic azimuth angle of the drilled hole are realized by the microprocessor, and thus, the problems that in the prior art, the depth of the drilled hole is difficult to measure and the three-dimensional space opening angle (such as the inclination angle and the azimuth angle) of the drilled hole cannot be accurately measured are solved.

Description

technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a drilling parameter detector for measuring the depth of a drilling hole and the opening angle (inclination angle, azimuth angle) in the three-dimensional space of the drilling hole. Background technique [0002] During the drilling process, the drilling rig needs to detect its drilling parameters in order to grasp the drilling situation in time. At present, measurement-while-drilling technology is usually used for measurement, but this technology is mainly used on 1,000-meter drilling rigs with large diameter drill pipes and non-rotating drill pipes. and other characteristics, the existing technology cannot well meet the measurement requirements of the drilling parameters of this type of drilling rig. Therefore, it is necessary to design a drilling parameter detection device that can adapt to the characteristics of ordinary drilling rigs. Contents of the invention [0...
