摘要 加拿大阿尔伯达盆地油砂资源丰富,Athabasca矿区是盆地中最大的油砂矿区,含油层段为白垩系Mannville组,矿区的目的层为潮汐环境下典型的曲流水道沉积。由于油藏曾发生生物降解作用,油矿地层沥青油黏度可达1×104~100×104 mPa.s。油砂开发主要采用露天开采和钻井开采方法,属钻井开采法的SAGD技术的机理是通过向油藏注入高温蒸汽,使固体沥青油变为可流动的原油,流入采油井筒中而被采出。连续油层厚度、隔夹层和气水层的分布以及水平井段的有效长度影响蒸汽腔的扩展和注汽效率。除考虑孔隙度、泥质含量、含油饱和度和电阻率外,SAGD开采方式下油砂的有效厚度识别标准还考虑连续油砂层、隔夹层和气水层的分布。油砂储量级别的确定,取决于储量的地质落实程度、资料获取情况和开发方案。 There is abundance of oil sand resources in Alberta Basin, Canada, where the Athabasca area is the largest one. The oil-bearing intervals in Athabasca area are located in Cretaceous Mannville Group, and the objective formation is typical meandering channel deposit in the tidal environment. As a result of occurrence of biodegradation, the reservoir oil viscosity is up to 1 × 10^4 -100 × 10^4 mPa . s. The main methods to develop the oil sands are open pit mining and drilling mining. SAGD technology belongs to drilling mining, whose mechanism is to inject high-temperature steam into the reservoir, so that the solid crude turns into flowing oil which flows into the wellbore to be produced. The expansion of steam chamber and the steam injection efficiency could be affected by the continuous reservoir thickness, interbed, gas/ water layer distribution and the net pay length in horizontal section. In addition to porosity, shale content, oil saturation and resistivity, the recognition standard of net pay thickness for SAGD technology should al- so consider the situation about continuous reservoir, interbed and gas/water layer distribution. The oil sands reserve classification is determined by the reliability degree of geological background, the data acqui- sition and the development plan.
