"Multi-factor controlling,four-factor entrapping and key-factor enrichment" of stratigraphic-lithologic reservoirs and exploration practice in Erlian Basin (IV)——Exploration practice

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 new accumulation 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.
