| 摘 要： | 大庆长垣在20世纪80年代以前伴生气中基本不含H2S,90年代以后发现油田伴生气中含有H2S,到2002年H2S含量已超过200 m g/m3(总外输),腐蚀油气管道的现象时有发生。对取自大庆长垣的8个样品(H2S气体和FeS粉末)进行了硫同位素分析,结果显示3δ4S值在+12.73‰~+16.10‰之间,认为H2S成因与生物作用关系不大,其很可能是松辽盆地基底石炭―二叠系中硫酸盐热化学还原作用(TSR)所生成。

| Abstract: | There was no H_2S in the associated gas of Daqing placanticline before the 80s of last century.By the middle of 90s,the content of H_2S in the associated gas was detected.At the year of 2002,the content of H_2S reached 200 mg/m~3 and many oil pipes were eroded.By analyzing the 8 samples(H_2S gas and FeS powder) collected from Daqing placanticline,the values of δ~34S of 8 samples vary at the range of +12.73‰～+16.10‰.The isotope feature of this H_2S is quite different compare with the H_2S which generated by ... |
