Abstract:

This text elaborates the technique problems of automatic north-finding gyroscope survey for super-deep geological drilling in the condition of high temperature of 280℃ and depth of 8000m. New low power and high temperature resistance electric components, integrate circuits and heat insulation material are adopted; and the techniques of high temperature welding, sealing, high temperature resistance and automatic north-finding gyroscopic survey are used to develop the borehole inclinometer which can not only ensure the quality and safety of the borehole in high temperature and high pressure environment and search out the related technologies for inclination survey.
