AI Technical Summary
In deep well oil reservoir development, packers suffer severe wear of the sealing rings due to bidirectional expansion and contraction deformation of the downhole tubing and gravel intrusion, affecting sealing life and production progress, resulting in high maintenance frequency and high costs.
A bidirectional compensator for deep wells is designed, which uses components such as graphite sealing rings, barrier cloth, elastic strips and guide ring frames to form a physical barrier to block sand and gravel. The reciprocating drive component drives the limit ring to rotate, achieving self-cleaning, reducing the wear of the sealing ring, and simplifying the maintenance process.
It effectively prevents sand and gravel from entering the sealing area, reduces the wear rate of the sealing ring, extends the seal life, reduces maintenance frequency and cost, and simplifies the maintenance process.
