Background

In the process of developing and exploiting crude oil, most oil fields contain hydrogen sulfide to a certain extent, the hydrogen sulfide has great harm to human life health, and the hydrogen sulfide also has serious influence on the oil field environment and production equipment.

Except controlling the production of hydrogen sulfide on the source, make hydrogen sulfide not produce or control its concentration in certain within range, can also adopt airtight gathering process flow through strengthening the technological process management, reduce and reveal the risk point.

With the development of oil fields containing hydrogen sulfide, the premise of safety production is to discover the generation and leakage of hydrogen sulfide in time. In the production and operation process, the wellhead position is the first position where liquid in the shaft is in contact with the atmosphere, and the hydrogen sulfide gas in the shaft is diffused into the atmosphere at the first time at the wellhead position, so that the wellhead position is the key position for detecting the hydrogen sulfide gas.

Therefore, a hydrogen sulfide gas detection sampler for an oil extraction wellhead needs to be researched and solved.
