On the one hand, it is an urgent need for China’s energy extraction, and on the other, it is a monopoly of foreign key technologies for small-diameter gyro continuous inclinometers. “Starting the development of a small-diameter gyro inclinometer!†At the beginning of 2015, space inertia was carefully considered and made this important decision.
For more than 30 years in the petroleum equipment manufacturing industry, we have independently developed products such as continuous inclinometers, wireless inclinometers, gyro inclinometers, and other companies that fill a number of technological gaps and develop small gyro inclinometers. Isn’t ceremonially handy?
The answer is not the case. Yue Bujiang, chief engineer of Aerospace Inertial Co., Ltd. explained in detail the difficulty. The small-gauge gyroscope continuous inclinometer is an advanced continuous-track parameter continuous measurement system with high accuracy, reliable use, simple assembly and wide application range. The difference from the existing products is mainly reflected in the miniaturization of the product's external dimensions - the external diameter is reduced from Φ89mm to Φ48mm. In this series of technical problems brought about by the reduction, the core sensor technology is second to none.
With the accumulation of heavy inertia in the field of inertial technology, the technological progress of 33 gyro sensors in the China Aerospace Science and Industry Third Institute has laid a solid foundation for the development of the product. While guaranteeing high reliability and high accuracy of sensor data acquisition, 33 successful implementations have been achieved. The miniaturization of the sensor. The success of this development also further supported the R&D structure of space inertia “One Axis and Two Wingsâ€. The “One Axis†is a Rotational Guidance System, and the “Two Wings†are a MWD measurement system and a high-temperature wireless LWD inclinometer system. Nowadays, with the small-diameter gyro inclinometer “Diamond Drillâ€, spaceflight inertia has turned its attention to the new “porcelain workâ€.
In recent years, the environmental protection situation in China has become increasingly severe. The demand for unconventional clean energy represented by natural gas and shale gas is very urgent. At present, the domestic similar products cannot perform related operations in horizontal wells and high inclination wells, but the small-caliber gyro inclinometer developed by space inertia can be used for horizontal well measurement. Aerospace inertia will actively seek related market opportunities in the future and further expand the scope of application of the product.

China successfully developed a small-caliber gyro inclinometer to fill the domestic gap
[China Instrument Network Instrument R&D] Recently, the small-diameter gyro continuous inclinometer independently developed by China Aerospace Science and Industry Inertial Technology Co., Ltd. (hereinafter referred to as space inertia) has successfully passed customer acceptance in Jianghan Oilfield. This is the first time that the gyro inclinometer has realized the continuous measurement of small boreholes in China. This product is also the first set of self-developed small gyro inclinometers that can realize autonomous north seeking and continuous measurement. It fills the domestic technological gap and represents the domestic The highest level of gyro inclinometer field. As China's onshore oilfields enter the middle and late stages of development, the application of small-borehole drilling and sidetracking of old wells has become more and more widely used. Although the inertial gyro continuous inclinometer technology is at the leading position in China, it has been limited by the size of sensors and cannot meet the needs of slim borehole measurement. In China, gyro inclinometers that can be used to measure small boreholes can only perform point measurement. It takes a long time to measure the well trajectory, and the integrity of the measured data is limited.
