Perm Researchers Develop Tool for Continuous Directional Drilling
The team designed a stabilization platform that enables continuous drilling of directional wells.
Researchers at Perm National Research Polytechnic University have developed a stabilization platform for continuous drilling of directional oil wells. The system significantly speeds up drilling operations by reducing equipment downtime.
Conventional directional drilling faces a persistent challenge: vibrations cause drilling equipment to shift, reducing the accuracy of optical gyroscopes. As a result, drilling must be paused periodically so the navigation system can be checked.
The new device addresses this problem through active stabilization of the navigation platform. Installed inside the drill pipe, it is equipped with gyroscopes and accelerometers. If the sensors detect that the drill string has shifted, a motor automatically rotates the platform in the opposite direction, maintaining a stable stream of navigation data.
The researchers say the technology could reduce drilling time by about 15%. It is suitable for both onshore and offshore drilling operations.
