【摘要】：致密油是目前中国比较现实的非常规油气资源,但致密油评估最终可采储量、可采系数和油气资源丰度等关键参数还没有系统的取值标准,尚需要借鉴国外成熟区关键参数。通过对西加拿大阿尔伯塔盆地Dodsland油田Viking组致密油刻度区进行解剖,开展了油气成藏条件和成藏特征研究,采用蒙特卡洛法与EUR法评价了其致密油资源量与最终可采资源量,在此基础上,确定了可采系数和油气资源丰度。结果表明,Dodsland油田Viking组致密油资源量为5.39×10~8t,可采资源量为0.79×10~8t;依据刻度区解剖结果,地质资源丰度为37.799×10~4t/km~2,可采资源丰度为5.565×10~4t/km~2;Dodsland油田Viking组致密可采系数为14.7%。通过详细解剖Dodsland油田Viking组致密储层油气地质特征,建立了油气地质条件基础参数体系。
[Abstract]:Dense oil is a relatively realistic unconventional oil and gas resource in China at present. However, there is no systematic criterion for evaluating the key parameters such as final recoverable reserves, recoverable coefficient and abundance of oil and gas resources in China. It is also necessary to draw lessons from the key parameters of foreign mature areas. By dissecting the dense oil scale area of Viking formation in Dodsland Oilfield in Alberta Basin, western Canada, the oil and gas accumulation conditions and characteristics are studied. The dense oil resources and the final recoverable resources were evaluated by Monte Carlo method and EUR method. The recoverable coefficient and abundance of oil and gas resources are determined. The results show that the dense oil resources and recoverable resources of Viking formation are 5.39 脳 10 ~ (8) t and 0.79 脳 10 ~ (8) t respectively. The abundance of geological resources is 37.799 脳 10 ~ (4) t / km ~ (-2), and the abundance of recoverable resources is 5.565 脳 10 ~ (4) t / kg ~ (-2) d ~ (dodsland) in Dodsland oilfield. The compactness and recovery coefficient of Viking formation in Dodsland oilfield is 14.70.The basic parameter system of oil and gas geological conditions is established by anatomizing the oil and gas geological characteristics of Viking formation in Dodsland oilfield.
