ANALYSIS OF RESERVOIR ROCKS BY TLC-FID AND ITS APPLICATIONS

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.
