摘要
通常测量油水饱和度的方法是以水为基准来区分油水量的,而稠油油藏火烧驱油后岩心中含水较少,甚至几乎不含水。鉴于此,用石油醚做萃取剂,利用紫外分光光度法测定含油量,用氦孔隙度仪测定孔隙体积及孔隙度,建立针对稠油油藏的含油饱和度测定新方法,并将它们应用于实际的岩心分析中,能较好用评价火烧驱油的效果及火烧驱油模型的燃烧情况,为稠油油藏开发方案设计和开发效果评价提供完整的基础资料。
Given that the traditional way of measuring oil and water saturation is based on the measurement of water while there is no water left in the core of heavy oil reservoir after combustion drive, this paper has sought to find a new method to measure the oil saturation of heavy oil reservoir by adopting petroleum ether as the extractant, ultraviolet spectrophotometry to measure oil content and helium porometer to measure pore volume and porosity. During the practical core analysis, this method managed to correctly evaluate the results of combustion drive and the burning process of the model thus providing complete basic materials conducive to program designs of heavy oil reservoir exploration and evaluation of effects.
