| 英文摘要 | Oil mobility is essential for the evaluation of shale oil resources, yet there has been limited research conducted on the oil mobility of low-to medium-maturity lacustrine shale. This study integrates multiple methodologies such as organic geochemistry, mineralogy, oil-kerogen adsorption-swelling experiments, and in-situ conversion pro-cess (ICP) models to evaluate the mobility and potential for shale oil in the lacustrine shale of the Yanchang Formation in the Yaoqu 1 (YQ1) well situated in the southeastern region of the Ordos Basin. The Chang 7 shales are categorized as highly favorable source rocks, nonetheless, the oil contained within these layers predomi-nantly exists in an adsorbed-swelling state, resulting in limited mobility as indicated by the oil saturation index, a modified oversaturation index, and production index. Therefore, the utilization of existing conventional tech-niques for shale oil exploitation is not viable for the Chang 7 shale characterized by low to medium maturity in the study area. Nevertheless, during the ICP, the quantity and mobility of oil within the Chang 7 shales exhibit a substantial increase as temperature rises. Moreover, once the Chang 7 type II shales reach a maturity level of around 0.91%Ro, they demonstrate noteworthy prospects for shale oil production. The findings of this study serve as a valuable reference for guiding the advancement of in-situ conversion process technology in the study area, while also offering substantial evidence for addressing the intricate challenge of crude oil mobility in low-to medium-maturity lacustrine shale reservoirs. |
