Abstract:

The gas production wellhead equipment is the key equipment of oil and natural gas field development. It is a direct bearing on the safety & environmental protection and protection for resource of oil and natural gas field to test the performance of the gas seal, to inspect and control its quality. This paper summarized the hydrostatic pressure seal test and gas seal pressure test to the wellhead, the paper focused on the discussion of the issues, such as how to set up high-pressure gas test device, how to perform hydrostatic test and high-pressure gas test and how to improve gas sealing performance of high-pressure wellborn equipment in combination with the situation of development of super high-pressure gas test devices.

Key words: gas production wellhead, gas sealing, divide, equipment, testing
