The core component of the north-seeking instrument is a gyroscope. Currently, the gyros used in most underground north-seeking systems at home and abroad are fiber-optic gyroscopes, liquid floating velocity integrating gyroscopes, dynamically adjustable gyroscopes, mechanical gyroscopes, etc.
The disadvantages of fiber optic gyroscopes are that they are expensive and have poor environmental adaptability. Without the installation of a high-efficiency thermos bottle, it is difficult to meet the measurement requirements of a well depth of 4000m, and the volume increases with the accuracy, making it difficult to meet the requirements of ordinary standard casing wells and drill pipes. and application requirements for small well diameters.
The liquid floating speed integrating gyro has good seismic resistance and small size, but it requires long-term work preparation and has poor temperature drift suppression ability, and generally works at a constant temperature.
Compared with the frame gyro, the accuracy of the dynamically tuned gyro has been greatly improved, but its resistance to shock and vibration is poor.
The north seeker based on mechanical gyroscope is relatively mature and has the advantages of high accuracy and low temperature drift. However, its shortcomings are also obvious, such as low reliability, limited dynamic range, and poor environmental adaptability.
Micro-electromechanical system (MEMS) inertial sensor is an inertial sensor developed based on MEMS technology. Due to its small size, light weight, low power consumption, mass production, low cost, and high reliability, it a series of traditional inertial sensors do not have the same advantages and are widely used in aviation, aerospace, navigation, meteorology, geology, automotive industry, industrial monitoring, robots, consumer electronics and other fields. With the development and needs of modern science and technology, MEMS gyroscope measurement accuracy requirements are getting higher and higher. Its performance continues to improve and its cost continues to decrease. It will become the main inertial device in the dual-use inertial technology market. North seekers based on MEMS gyroscopes therefore have a broad application market.
