MARGIN: auto 0cm" class=MsoNormal>man’,’serif’" lang=EN-US>Based on the composition and concentration variations of nitrogen compounds in the studied oil samples as well as the maturity indexes of saturated and aromatic biomarkers, the authors investigated the oil migration direction of 1st structural belt of Nanpu sag. The results show that the distribution and composition characteristics can obviously indicate oil fractionation effects. Due to weak fractionation, biomarker varies slowly between near-by wells; in contrast, due to strong fractionation and relatively insignificant influence of maturity, data of nitrogen compounds change significantly, which is favorable for the judgment of hydrocarbon migration. mas-microsoft-com:office:office" />
