Although the mechanical pulse generating device can bear higher temperature, the mechanical pulse generating device has higher cost, complex maintenance and higher assembly precision, and common equipment can not meet the maintenance requirement. The metal piston type solves the problems of high temperature environment and complex maintenance thereof, but has low transmission efficiency. For the situation, the pulse generating device is developed by long-time design, research and development and repeated verification of our company, and is called a magnet type double-balance pulse generating device. The pulse generator has stronger general performance than the existing pulse generator, and meets the drilling requirements of more types. The measuring instrument has smaller mechanical structure size and is also suitable for various requirements of drilling from large well bore to small well bore. The measuring instrument can normally work under the condition of high temperature under the well, and the high temperature resistance can reach 200 ℃. The working pressure can reach 150MPa. The instrument can be salvaged, and part of water conservancy accessories can be replaced on site, so that the installation is convenient. Compared with the existing pulse generating device, the magnet type double-balance pulse generating device has stronger applicability and high-frequency transmission rate, and can be connected with other composite inclinometry and detection equipment thereof in a hanging manner, thereby greatly facilitating the use requirements of drilling clients.
