胜利油田孤岛原油中有机硅化合物的发现及其石油地质意义

The Discovery of Organo Silicon Compounds in Gudao Crude oils from the Shengli Oilfield and Its Significance in the Petroleum Origin

采用溶剂萃取法从胜利油田孤岛原油中分离得到浓缩的含氧化合物，再用柱色谱分离得到有机硅及其它组分。用红外、电子能谱、气相色谱－质谱法分离鉴定了有机硅组分。鉴定出的有机硅化合物有硅Ｓｉ３－Ｓｉ７的甲基硅氧烷和Ｓｉ３－Ｓｉ５的环甲基硅氧烷以及三甲基硅的衍生物。资料表明：在高等和低等生物体中还不能肯定含有Ｓｉ－Ｃ键的有机化合物。因此，原油中有机硅化合物的发现是原油无机成因的一个证据。

The method of solvent extraction was employed to obtain concentrated oxygen containing compounds from the Gudao crude oil and they were then separated by column chromatography packed with silica to get organosilicon compounds and other fractions. The organosilicon compounds were separated and identified by IR electron spectrum and GC-MS method.
