“…(3) The triaxial gyroscope (fiber-optic gyroscope) is a precise optical sensor that has high requirements for vibration electrical resistance. However, the working conditions during trenchless construction are extremely complex and harsh where the requirements for vibration electrical resistance cannot be guaranteed (4) Temperature drift in a triaxial gyroscope is large and is still an unsolved problem, though a number of researchers have carried out studies of algorithms to treat temperature drift [8][9][10] (5) Due to the Faraday magneto-optic effect, the polarization plane of the light in the triaxial gyroscope will rotate [11]. As a result, the gyroscope can still be affected by electromagnetic interference.…”

Trenchless technology is a type of construction that requires pipelines to be laid in a subsurface horizontal hole drilled by a trenchless drilling rig. To prevent drilling accidents during construction, the drilling trajectory needs to be controlled in real time according to the value of the tool face angle. However, existing tool face angle sensors cannot precisely control a trenchless drilling course due to a number of limitations such as low resolution, large temperature drift, and high requirements for accurate installation. In this regard, this paper presented a new tool face angle sensor based on the change in electrical resistance value. The tests mainly include four aspects, namely, accuracy, repeatability, resolution, and temperature drift. Numbers of tests showed that the measurement error was ±6 degrees, the repeatability was 2.54%, the minimum resolution was 6 degrees, and the temperature drift had no effect during the temperature changes from 0 to 80 degrees, which proved that the sensor is applicable for practical trenchless working conditions.

Abstract. The working environment in hot dry rock boreholes, encountered in deep geothermal investigation drilling, and ultra-deep geological drilling (up to 5000 m), is very difficult at the present stage. We have developed a drilling trajectory measuring instrumentation (DTMI), which is based on the interference fiber optic gyro (FOG). This can work continuously, for 4 hours, in an environment where the ambient temperature does not exceed 270 °C and the pressure does not exceed 120 MPa. The DTMI is mainly divided into three parts: an external confining tube, a metal vacuum flask, and a FOG measurement probe. Here we focus on the mechanical design, strength, and pressure field simulation analysis for the external tube, the structural design and temperature field simulation analysis for the vacuum flask, and the FOG Shupe error analysis and compensation in the temperature field. Finally, through the engineering applications of SK-2 east borehole of the China Continental Scientific Drilling Project (CCSD) and the geothermal well of Xingreguan-2, the data measurements of the drilling trajectory were used to analyze the stability of the DTMI. The instrument realizes long-duration, high stability, work in the process of making trajectory measurements in an ultra-deep hole. The instrument has the characteristic of anti-electromagnetic interference, and enables work to be carried out in the blind-zone of existing technologies and instrumentation. Therefore, DTMI has great potential in the promotion and development of geological drilling technology.

“…By means of discrete calibration method, these parameters can be acquired roughly with the aid of rotation gimbals in RINS. 16,17 However, the inertial components of RINS are susceptible to the environment, such as ambient temperature, 18,19 magnetic field, 20 and vibration. 21 Even through the conventional calibration method, an overall calibrated system is still influenced by calibration errors.…”

Rotational inertial navigation system can significantly improve the navigation accuracy by rotating the inertial measurement unit about gimbals periodically. The precise calibration for installation errors and scale factor errors in rotational inertial navigation system can contribute to better navigation performance further. Especially in application requiring excellent azimuth precision, the horizontal rotation modulation will be badly required to modulate the vertical sensors’ errors as periodic variation, which can make inhibiting effect on the navigation errors. However, it also enlarges the impact of specific errors, which contains gyro’s scale factor error and the installation errors of inertial components. To meet the requirement of navigation precision, this paper has made error analysis and established mathematical model for a proposed horizontal rotation modulation in dual-axis rotational inertial navigation system. The crucial error parameters can be calibrated based on the measurements of attitude and velocity output without additional equipment. The results of experiment performed in an actual system demonstrate that navigation accuracy has been improved significantly, fully illustrating the significance and necessity of the calibration for specific errors in the horizontal rotation modulation.
