en.Wedoany.com Reported - Perm National Research Polytechnic University (PNIPU) in Russia has developed a device for continuous drilling of inclined oil wells, claimed to be the world's first solution of its kind.

When drilling inclined wells, the drill string experiences severe vibrations due to the impact of the drill bit, causing optical gyroscopes to lose accuracy and requiring drilling to be paused for data calibration. University experts note that such downtime can account for up to 15% of total drilling time.

PNIPU experts have designed a gyroscope stabilization method and built a corresponding stabilization platform. The platform, equipped with a gyroscope and accelerometer, is mounted on the motor housing inside the drill pipe. When sensors detect that the drill string has started rotating, the motor rotates the platform in the opposite direction at the same speed, keeping it stationary, thereby enabling uninterrupted operation under rotating drill string drilling conditions.

The research team states that the device is suitable for various types of inclined wells both on land and offshore. Using this platform can save 4-5 days per well, while drilling an inclined well typically takes about a month. For a project, the savings can amount to tens of millions of rubles.
