Comparison of Ordos and Foreign Similar Basins and Prediction for Mesozoic Oil Reserves in Ordos Basin
详细信息   
摘要
West Siberia,Paris and Illinois basins were chosen to do comparison with Ordos Basin.The Ordos Basin is a cratonic basin that was developed above aulacogen base,so it has good tectonic basis for accumulating abundant oil and gas resources.Besides continental sedimentation,limited distribution of source rocks and complex trap types,all the other geologic conditions of Mesozoic Ordos Basin are similar to those of the three foreign basins.The results of basins comparison and calculation show that the Mesozoic Ordos Basin can possess proved oil reserves as 17.21 × 108t(based on West Siberia Basin),22.67 ×108t(based on Paris Basin) and 24.40 × 108t(based on Illinois Basin),indicating that the Mesozoic Ordos Basin has great oil resource potential and exploration prospect.
