摘要

There widely exists oil and gas accumulation of migratory with multiplied characteristics in Bozhong region. Located in southwest of Bozhong Depression region and west Bonan of raised region, the geochemical analysis of BZ26-2-1 crude oil samples of Guantao Formation showed that a double characteristics between degradable and non-degradable for crude oil existed in the region: complete distribution of normal paraffins series of high abundance, abundant 25-norhopane series was measured by GC/MS analysis with high absolute concentration. So, the phenomena proved that the crude oil of Guantao Formation was infused twice at least.
