Petroleum Resource Constitute Of Erlian Basin And Its Exploration Potential Analysis

In this paper, a resource constitute predicting model suitable for Erlian basin is established on the basis comprehensive analysis on information acquired during the exploration in Erlian basin. It is shown from quantitative evaluation results that provable oil reserve is finally 891.79 million tons and remaining reserves 657.78 million tons. From analysis on remaining resource constitute,87 reservoirs are of over 2 million tons and totally 455.53 million tons. Resource constitute of low exploring areas is quantitatively predicted by using quantitative relation models which is established through analyzing the correlativity between resource controlling parameters and geologic parameters of hydrocarbon migrating-accumulating unites. And the prediction model of proved reserves rising tendency is also established. And from its analysis results, incremental proved oil reserves in Erlian basin will be 54 million,52 million,51 million, 49 million and 47 million tons every five years from 2008 through 2032. It is indicated from comparison and analysis that lithological reservoirs in Erlian basin are characterized by formation at the early stage, multiple affluxion pathways, favorable preserve conditions and extensive distribution and they are currently the most favorable exploration targets. This paper analyzes forming conditions of buried-hill reservoirs and gas reservoirs in Erlian basin and illustrates their exploration potential.
