With the continuous growth of global demand for oil and gas, offshore oil and gas exploration and exploitation have gradually expanded to deep-sea, far-sea and complex geological conditions. In this process, ensuring the safety, efficiency and reliability of drilling and extraction has become a crucial task. As a high-precision measurement tool, the inclinometer has been widely applied in the detection of the levelness of blowout preventers (BOP) in offshore drilling and the attitude monitoring of oil pumping units in recent years, providing strong support for the safe production and intelligent management of the oil and gas industry.
