Analysis of micro-infrared spectrum of unity oil and gas inclusions

摘要

Viewing from analysis result of inclusions from three wells, it can be seen that, hydrocarbon reservoir characteristics belong to the first and second stage, dominated by the last stage. Infilling oil and gas are medium or light oil. There is little difference in methene and methyl ratio of the oil inclusions with light yellow fluorescent and the oil inclusions with yellow green fluorescent, showing that inclusions compositional maturity basically agree. It is a good analysis method to test the composition of unity oil and gas inclusions with micro-infrared spectrum, oil and gas reservoir forming stage and oil and gas inclusions maturity can be well divided. In the further investigation, attention should be put on how to remove the influence of shoulder-like absorbing peak to the peak area.
