Selection And Correction Of Key Parameters In Quantitative Evaluation Of Shale Oil Resources

With core sampling of different depth of different lithology,and the displacement of the sample before and after the NMR experiment,combined with the thermal parameters of samples before and after extraction,the establishment of pyrolysis parameters and NMR spectra of T₁-T₂,we can determine the shale oil moving limit.A logging evaluation model of shale in the Qijia Gulong depression and Longhupao depression of the Qingshankou formation in the Songliao basin is established to characterize the heterogeneity of the area.Using the source rock samples of The Qingshankou formation in different burial depth?different evolution degree?will get us experimental analysis,residual compensation coefficient,residual oil hydrocarbon evaluation parameters to determine the area,and finally get us the corrected parameters of oil.Combine the volume method with the correction rate parameter,we can calcule the shale oil resouces and movable oil resources amout of effective layer of Qing 23 and Qing 1 foramation,meanwhile we can predict that the shale oil favorable distributing area of the Qing 1 formation is from the Yingshen 1 well?as the center?,outwards a transition to Ha 1 well,Gu 14 well,Gu 11 well and Gu 501 well,and movable oil resources volume near the maximum distribution can reach 3.6×10⁵t;and the shale oil of the Qing 23formaion has favorable areas of distribution in the central part of the Longhupao depression,near the west of Gulong depression,and the northern part of the Gulong depression,meanwhile movable oil resources volume near the Gu 692 well has the maximum amount up to 8.2×10⁵t.
