【摘要】 页岩油储量评价方法尚未形成行业规范，古龙页岩油地质储量估算方法未见报道。通过分析松辽盆地古龙页岩油藏的特殊性，以烃源岩成熟度、有机碳含量、储层孔隙度、原油密度、黏度、压力系数6个参数评价古龙页岩地质条件，建立了以容积法结合开发箱体概念的古龙页岩油藏储量计算方法。结果表明：古龙页岩以泥级为主，黏土含量高、含油性好、资源前景好；以6个参数评价古龙页岩地质条件有利于含油，且易于流动高产；分别对容积法的计算参数进行了阐述，并针对古龙页岩油藏进行了参数的定量表征；以开发箱体概念将古龙页岩油层纵向划分为上箱体、中箱体、下箱体，下箱体物性最好，压力系数高、应力差小、脆性指数相对低，是储量估算最优层段；应用容积法计算古龙凹陷A1区块青一段Q₁—Q₄油层地质储量为12.68×10⁸t，新增含油面积1 413.2 km²。研究成果为古龙页岩油高效开发提供了有力的依据。更多还原

【Abstract】 Reserves estimation method for shale oil has not formed industry standards,and relevant estimation method for OOIP of Gulong shale oil has not yet been issued. Through analysis on specific characteristics of Gulong shale oil reservoir in Songliao Basin,6 parameters including source rock maturity,organic carbon content,reservoir porosity,oil density,oil viscosity and pressure coefficient are used to evaluate geological conditions of Gulong shale and to establish reserves calculation method combining volumetric method and development compartment concept. The results show that Gulong shale is mainly clay-sized,with high clay content,high oil-bearing property and much resource potential. 6 parameters evaluated geological conditions of Gulong shale are favorable for oil-bearing and oil mobility for high production. Calculation parameters of volumetric method are respectively illustrated,and reservoir parameters of Gulong shale oil reservoir are quantitatively characterized. Development compartment concept is applied to divide Gulong shale oil reservoir into upper,middle and lower compartments,among which lower compartment has the best property,highest pressure coefficient,less stress different and low brittleness index,being optimal interval for OOIP estimation. Volumetric method calculated OOIP of Q₁-Q₄ layers of Member Qing-1 in Block A1 in Gulong Sag is 12.68×10⁸t,with increased oil-bearing area of 1 413.2 km². The research provides reliable evidence for efficient development of Gulong shale oil.更多还原
