该文从环境温度、环境湿度、色谱棒的活性、点样量、样品损失及校正因子等影响因素出发,讨论了各种影响因素对分析结果的影响.选定仪器条件,并严格控制环境温度、湿度及色谱棒活性,采用校正因子法进行定量,结果表明该实验相对标准偏差均小于5%,证实了TLC-FID棒状薄层色谱的可行性;通过与校正样品对比,计算出岩样中的抽提物含量(T值).同时,将此技术用于塔里木盆地塔河油田某口井的有机地化描述,根据T值讨论了储层流体的族组成变化,并准确地确定了该油藏现今的油水界面.

Environmental temperature,humidity,chromatobar activity,quantity of samples,loss of sample and correction factors have influenced on analysis results.Under fixed instrument condition,if environmental temperature,humidity and chromatobar activity were controlled and correction factors were used,the analysis results showed that relative deviation is less than 5%.This has proved TLC FID's feasibility.Comparing with correction samples,the content of the extractives in rocks was calculated.When this technique was applied to describe the geochemistry of oil reservoir of Tahe oilfield,the changes of group composition of fluids were discussed and present oil water contact was determined.
