Problems solved by technology
[0002] In the prior art, borehole inclinometers have been widely used in coal fields and petroleum geological exploration. They are generally composed of ground control instruments and downhole probes. Most of them are connected by cables to transmit signals, so they can only measure vertical holes; However, in coal mines, the method of using built-in cables in drill pipes for signal transmission requires high technical requirements and high costs.

The invention relates to a cable-free borehole clinometer and a synchronous inclinometry method thereof based on a synchronization technology. A synchronous machine and a probe tube provided by the invention are connected by a communication line, the borehole clinometer is synchronized through a synchronization key arranged in a keyboard circuit of the synchronous machine in the measurement process, the synchronous machine and the probe tube are enabled to start sampling synchronously according to a preset time interval, and then the communication line of the probe tube is disconnected, the probe tube is fed to a borehole for collecting and storing signals from sensors, the synchronous machine operating synchronous with the probe tube is used for recording and storing the validity of each measurement point, after the measurement is finished, data collected by the probe tube is transmitted to the synchronous machine through the communication line, and the synchronous machine calculates the valid measurement points and displays the dip angle and the azimuth angle of each measurement point. According to the invention, an inclinometry cable and computer configuration are reduced, and the convenience is brought for the carrying and use; and as the synchronization technology is adopted, no cables are needed in the measurement process, and the cable-free borehole clinometer and the synchronous inclinometry method can be used for measuring various boreholes such as pitch-up, downdip, horizontal and vertical boreholes without cables.
Description
technical field [0001] The invention belongs to the field of geological exploration instruments, and in particular relates to a cableless drilling inclinometer based on synchronous technology and a synchronous inclinometer method thereof. Background technique [0002] In the prior art, borehole inclinometers have been widely used in coal fields and petroleum geological exploration. They are generally composed of ground control instruments and downhole probes. Most of them are connected by cables to transmit signals, so they can only measure vertical holes; However, in coal mines, the method of using built-in cables in drill pipes for signal transmission has high technical requirements and high costs. Contents of the invention [0003] The technical problem solved by the present invention is to provide a cableless drilling inclinometer based on synchronous technology, which is low in cost, reliable in performance, easy to use, and can measure drilling in any direction such ...
