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5.39×108 t,可采资源量为0.79×108 t;依据刻度区解剖结果,地质资源丰度为37.799×104 t/km2,可采资源丰度为5.565×104 t/km2;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: Tight oil is considered a realistically superior, unconventional oil and gas resource. However, systematic standards regarding various key parameters of tight oil such as estimated ultimate recovery (EUR), recoverable coefficient, and oil-gas resource abundance have not yet been effectively established in China. Standard values from mature tight oil calibration areas in other countries are often used as reference. This study conducts an in-depth analysis on a tight oil calibration area of the Viking Formation at Dodsland Field located in the Alberta Basin in western Canada in order to examine the oil-gas reservoir conditions and characteristics. The tight oil reserves and ultimate recovery of Viking Formation are evaluated using the Monte Carlo method and the EUR method, based on which the recoverable coefficient and oil-gas resource abundance are also determined. The results have shown that: 1) the tight oil reserves of the Viking Formation at Dodsland Field are 5.39×108 t, of which the recoverable reserves are 0.79×108 t; 2) according to the study results of the calibration area, the geological resource abundance is evaluated to be 37.799×104 t/km2, of which the recoverable resource abundance is 5.565×104 t/km2, and 3) the recoverable coefficient of the evaluation area is 14.7%. Based on the analysis of oil-gas geological characteristics of the tight reservoir at Viking Formation, a basic parameter system featuring tight oil-gas geological conditions can be constructed.

Key words: estimated ultimate recovery, recoverable coefficient, oil-gas resource abundance, tight oil, Monte-Carlo method
