  • The amount of shale oil and its characterization are key issues in the study of shale oil. At present, many scholars use a variety of methods to evaluate the amount of shale oil, and use the calculated amount of hydrocarbons to analyze its influencing factors; however, there is lack of detailed research on the storage space for shale-oil and it's influencing factors. In view of this issue, gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS), soxhlet extraction (SE), field-emission scanning electron microscopy (FE-SEM), low-temperature nitrogen adsorption (LTNA), high-pressure mercury intrusion (HPMI), and X-ray diffraction (XRD) were used to analyze and compare samples from two wells located in different deposition locations. The unconventional Well BYY2 and BX7s were drilled in the depocenter and distal area of the Qianjiang Formation, respectively. Controlled by differences in the organic matter type and sedimentary environment, the organic matter in Well BYY2, which was found to be characterized by laminar shale, mainly originated from aquatic algae. The results showed that as the total organic carbon (TOC) content increased, the amount of shale-oil in the pores increased. Shale-oil was mostly stored in mesopores and macropores that had been preserved by dolomite minerals of a biogenic origin and also occurred in pores sized 5–200 nm and > 1 μm. Dolomite minerals of a biogenic origin and clay minerals contributed to the occurrence of shale-oil. In comparison, the organic matter in Well BX7 has been greatly influenced by terrestrial organic matter. Pores in the massive mudstones from Well BX7 were determined to be mainly mesopores preserved by clay minerals and quartz, and the shale-oil was mostly stored within the pores of < 40 nm. When the TOC content was ~2.5 wt.%, the generated shale-oil reached saturation. Clay minerals contributed to the occurrence of shale-oil, whereas quartz only contributed to the occurrence of shale-oil in macropores.
