Short summary

This paper developed a drilling trajectory measuring instrumentation (DTMI) based on the interference fiber-optic gyro (FOG), which can work continuously, for 4 h, in an environment where the ambient temperature does not exceed 270 °C and the pressure does not exceed 120 MPa in an ultra-deep borehole. The DTMI has the characteristic of anti-electromagnetic interference; therefore，this DTMI has great potential in the promotion and development of geological drilling technology.
