稠油具有以下几个方面的特点,一是其胶质沥青含有量较高;二是其在油层中有着较高的粘度;三是其流动阻力大,有时会难以流动。这些特点使得稠油的开采不能使用常规的开采技术,否则,难以获得较好的经济效益。后来,研究发现,其粘度会随着温度的升高而快速下降,从而可以增强很大的流动性,因此,自二十世纪伊始,国内外的石油企业开始越来越多地使用热力采油方法。本文论述了目前采用的较为成熟的稠油热采技术。
Heavy oil has the following characteristics: First, its high content of gummy bitumen; Second, it has a high viscosity in the reservoir; Third, the flow resistance, and sometimes difficult to flow. These features make the exploitation of heavy oil can not use the conventional mining technology, otherwise, it is difficult to get better economic benefits. Later, the study found that its viscosity drops rapidly with increasing temperature, which can enhance the great mobility, therefore, from the beginning of the twentieth century, domestic and foreign oil companies began to use more and more heat recovery method . This article discusses the more mature heavy oil thermal recovery technology currently used.
