Analysis of Genesis of Hydrogen Sulfide in a Bohai Oilfield
The genesis of hydrogen sulfide is of great significance for studying oil and gas reservoir formation and hydrogen sulfide treatment.There are three types of genesises of hydrogen sulfide,namely thermal cracking of sulfur-containing organic compounds、thermochemical reduction of sulfates and biogenesis.The results indicate that the large amount of SRB and sulfate carried in the drilling fluid is the main cause of H2S generation in oil fields,while the thermal cracking of sulfur-containing organic compounds is a secondary cause.
