Abstract: As the super and most petroliferous basin in China, Songliao Basin has achieved strategic breakthroughs in the exploration and evaluation of Gulong shale oil, of which the potential and scale of resources remain unclear. Based on the extensive geochemical data including total organic carbon (TOC), rock pyrolysis, vitrinite reflectance and pressure-reserved core, in combination with logging and production data, a systematic evaluation was conducted on various types of shale oil, primarily in Qijia-Gulong sag. A classification scheme using organic matter maturity and reservoir type as key indicators was developed for shale oil in Songliao Basin. As a result, grading standards for shale oil were established based on the key parameters such as TOC content, oil content, effective porosity, and oil saturation. A shale oil resource evaluation method was created, involving the key technologies such as precise evaluation of oil content, light hydrocarbon recovery and calibration of recoverable coefficient. Based on dynamic production data, the geological resource potential of shale oil under current technological conditions was assessed, achieving the predictive analysis of resource recoverability. The comprehensive evaluation indicates that Qijia-Gulong sag contains medium- to high-maturity shale oil resources of 107.73×108t (including 42.08×108t of Class Ⅰ resources and 33.67×108t of Class Ⅱ resources), with technically recoverable resources exceeding 8×108t. Additionally, the geological resources of dissolved gas are estimated to be 1.75×1012m3, and the technically recoverable resources amount to 0.13×1012m3. The resource evaluation results suggest that the favorable shale oil resources in Songliao Basin are mainly distributed in Qijia-Gulong sag, as being the essential strategic replacement resource. With future advancements in development technologies, the recoverable potential of shale oil is expected to increase significantly.

摘要: 松辽盆地是中国已采出油气最多的大型超级盆地,古龙页岩油勘探评价已取得战略性突破,但资源潜力和规模尚不明确。基于古龙页岩的有机碳、岩石热解、镜质体反射率、保压岩心游离烃含量等大量地球化学分析数据,结合测井资料和生产数据,系统开展了以齐家—古龙凹陷为主的多类型页岩油的资源评价。建立了以有机质成熟度、储集类型等为核心指标的松辽盆地页岩油分类方案,制定了以总有机碳、含油量、有效孔隙度和含油饱和度等为核心参数的页岩油分级标准,形成了以含油量精细评价、游离烃恢复和可采系数标定等为核心技术的页岩油资源评价方法。基于生产动态数据,对页岩油的地质资源量进行了现有工艺技术条件下的技术可采资源潜力评估,实现了页岩油资源可利用性预测分析。综合评价认为:松辽盆地齐家—古龙凹陷中—高成熟页岩油的地质资源量为107.73×108t (其中,Ⅰ级地质资源量为42.08×108t,Ⅱ级地质资源量为33.67×108t),技术可采资源量超过8×108t;溶解气的地质资源量为1.75×1012m3,技术可采资源量为0.13×1012m3。资源评价结果显示,松辽盆地古龙页岩油的有利资源主要分布在齐家—古龙凹陷,是松辽盆地重要的战略接替资源,预计在未来随着开采技术升级,页岩油的可动用潜力将进一步增大。
