中国已探明石油可采储量约62亿吨,其中已累计采出34.6亿吨,剩余27.4亿吨。按目前的采油量计算,可供开采17年。在新增探明石油储量中低渗透和稠油等低品位储量比例逐年升高,未动用储量中大部分为难采储量,已开发油田总体进入高含水、高采出阶段,产量总递减已成明显趋势。稠油是世界经济发展的重要能源,目前国内对稠油的开采已具有多种成熟的工艺,因此,中原油田也必须加快向稠油开采进军的步伐。 China has proven about 6.2 billion tons of oil recoverable reserves, of which 3.46 billion tons have been mined and the remaining 2.74 billion tons. Calculated at the current amount of oil production, mining for 17 years. In the newly-added proven oil reserves, the proportion of low-grade reserves such as low-permeability and heavy oil increased year by year with most of the unused reserves being recoverable reserves. The developed oilfields generally entered the stage of high water cut and high production and the total output decline had become Obvious trend Heavy oil is an important energy source in the world economic development. At present, the exploitation of heavy oil in China has a variety of mature technologies. Therefore, the Zhongyuan Oilfield must speed up the pace of heavy oil exploitation.
