摘      要：Comparative analyses of petroleum generation potential,reservoir volume,frackability,and oil mobility were conducted on 102 shale cores from the Dongpu *** show the shale has high organic matter contents composed of oil-prone type I and type II kerogens within the oil *** types of pores and fractures exist in the shale,with a porosity of up to 14.9%.The shale has high brittle mineral contents,extensive fractures,and high potential for oil mobility due to high seepage capacity and *** the petroleum generation potential of the shale at Well PS18-8 is relatively greater than that at Well PS18-1,oil content of the latter is greater due to the greater *** porosity and fracture density observed in Well PS18-1 are greater and more conducive to shale oil *** the shales in Wells PS18-1 and PS18-8 have similar brittle mineral contents,the former is more favorable for anthropogenic fracturing due to a higher preexisting fracture ***,the shale at Well PS18-1 has a higher seepage capacity and overpressure and therefore a higher oil *** fracture density and overpressure play key roles in shale oil enrichment.
