Implication

Field tests demonstrate significant improvements in sealing performance in shale oil wells, indicating the effectiveness of temperature-sensitive lost circulation material.

Key Points

The activated temperature-sensitive lost circulation material improved sealing performance significantly.
In field tests, the success rate of plugging increased from 32% to 82.5% with temperature-sensitive lost circulation material.
The prepared material shows compatibility with local saltwater-based drilling fluid, enhancing drilling cycle efficiency.
Testing showed that particle size could expand significantly under high temperature and pressure, enhancing sealing capability.
