Abstract:

Based on four typical examples of successful exploration for stratigraphic-lithologic reservoirs in Erlian Basin, the research on the accumulation mechanism of “Multi-factor controlling, four-factor entrapping and key-factor enrichment”of stratigraphic-lithologic reservoirs is deepened, and newaccumulation models of stratigraphic-lithologic reservoirs are established. The result shows that petroleum exploration has made a significant breakthrough. Four stratigraphic-lithologic reservoir blocks with reserves of 30 to 50 million tons have been discovered successively in Bayindulan Sag,Wuliyasitai Sag, Jiergalangtu Sag and Saihantala Sag.

Key words: high resolution sequence stratigraphy, base level cycle, salt lake deposit, sandbodies distribution;Zhongshi Oilfield
