Material selection of gas-well wellhead assembly and application in high-sulfur gas-well

摘要

For natural gas well, material selection of gas-well wellhead assembly is an important factor of gas production system life. In order to ensure the long-term development of gas wells, this paper mainly introduces the material selection of gas-well wellhead assembly, proposes the optimization idea and technique of gas-well wellhead assembly. By taking W well as an example, this paper optimizes the material selection of gas-well wellhead assembly for W well. For application, the optimal materials of gas-well wellhead assembly in W well have good performance of corrosion resistance.
