【摘要】 氢气流量、扫描速度和色谱棒活度影响样品的分析结果及重复性。选择分析条件是成败的关键。氢气流量（Ｌ）值选用１８０ｍｌ／ｍｉｎ，扫描速度３０ｓ／次，并控制环境湿度与温度保持色谱棒活性的稳定，以及针对不同类型的原油选取不同的校对因子值，结果表明相对偏差均低于１０％，证实ＴＬＣ－ＦＩＤ棒色谱分析的可行性。将此技术应用于塔中四号构造油藏的有机地化描述，发现了储层内的富沥青层（推测是古油水旱面的遗迹），并准确地确定了该油藏的现今油水界面。更多还原

【Abstract】 Hydrogen flow rate, scan speed and chromatobar activity have influence on repeatabilityof sample analysis results. When hydrogen flow rate (L) is 180ml per min, scan speed is 30seach time, then control humidity and temperature to certain condition, and keep the activityof the chromatobar, choose different correction factor values according to different crudeoils. The analysis results show that relative deviation is less than 10%. This has proved thefeasibility of TLC-FID chromatobar analysis. The authors applide this technique in describing the geochemistry of Tazhong-4 structural oil reservoir, discovered a bitumne--rich layer inthe reservoir, and determined the present oil-water boundary of the reservoir.更多还原
