摘要
本方法主要采用毛细柱上烃类凝聚新技术,其要点以色谱仪进样器的石英内衬管为样品管,利用控温的气化室(250℃)及载气将岩样中的C_5—C_(35)残余烃逐出,在毛细柱头上凝聚.然后程序升温进行色谱分析.试验证明,本方法提供的谱图和数据,对判别油、气、水层具有实际意义,同时本方法还可进行原油C_5—C_(35)全烃分析.
In the study, the new technique of hydrocarbon condensation on capillary column was mainly applied, with the quartz inner tube of the injector in chromatographic analyser as sample tube. Residual hydrocarbon C6-C35 in rock samples were expelled by carrier gas in pneumatolytic chamber at con-trolled temperature ( 250 ℃ ), which condensated on the head of capillary column, and then programme temperature started for chromatographic anal-ysis. Tests show that the chromatographs and data obtained by the method are practical in identifying oil, gas, and water formations. Meanwhile the method would be used in whole hydroearbon ( C_5-C_35 ) analysis.
