Abstract
To improve the performance of the cone bit bearing seal, experimental study and simulation analysis of seal failure were carried out, and optimization of the seal was conducted. Results show that d...
Highlights
Cone bit is the main rock-breaking tool in oil and gas drilling engineering, whose performance and service life directly affect the quality of the well, the drilling efficiency, and the drilling cost
The average compression ratio of the moving rubber ring is more than 27% and the ratio of the static rubber ring is more than 31%
We evaluated the performance of the optimized seal structure by investigating the wear of the metal rings of original seals and optimized seals
Summary
Cone bit is the main rock-breaking tool in oil and gas drilling engineering, whose performance and service life directly affect the quality of the well, the drilling efficiency, and the drilling cost. Keywords Cone bit bearing seal, failure analysis, optimization, FEM, contact pressure distribution, average compression ratio, wear A comparative investigation of the original seal and the optimized seal was conducted on contact pressure distribution, average compression ratio of rubber rings, and wear of metal rings.
