研究硫化氢(H2S)成因对于治理油气成藏具有重要意义.H2S有 3 类成因,具体为含硫有机化合物热裂解成因、硫酸盐热化学还原成因和生物成因.结果表明,钻井液中携带大量硫酸盐还原菌和硫酸盐是油田H2S的主要成因,含硫有机物热裂解是油田H2S的次要成因.
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.
