Abstract

Based on the analysis of the enrichment factors for stratigraphic-lithologic reservoirs found in Erlian Basin, the enrichment of the stratigraphic-lithologic reservoirs is considered to be controlled by three main factors, including abundant oil sources, high quality sand body traps and main confluent passageway. Abundant oil sources are the background for the enrichment; high quality sand body traps which spread broadly are the key point for the enrichment; and the main confluent passageway is the best way for enrichment of the stratigraphiclithologic reservoirs.
