China is a broad territory, and natural gas in different regions has great differences in the aspects of water content, sulfur content, particulate matters, air source pressure and the like. This presents great difficulties in sampling natural gas from the wellhead, particularly for high sulfur-containing gas reservoirs where the fluid is in equilibrium with elemental sulfur under the conditions of the original gas reservoir, and the saturation of sulfur in the fluid changes with changes in temperature and pressure. When the temperature and pressure are lowered, elemental sulfur is precipitated and ice-like hydrates and polysulfides are formed. Since sampling of the high sulfur-containing gas reservoir necessarily involves changes in fluid temperature and pressure, overcoming the above problems and obtaining a representative gas sample in the sampling process becomes a key and difficult point for sampling the wellhead of the high sulfur-containing gas reservoir.
Natural gas is a gaseous fossil fuel consisting primarily of methane. It is mainly found in oil fields and natural gas fields, and also in coal seams in small quantities.
