我国稠油资源储量大,重油沥青资源分布广泛,为满足工农业生产对能源日益增长的需求,稠油日益引起各国的重视。密度大、凝点高、粘度大、流动困难是我国稠油资源的突出特点。因此,降低稠油粘度,改善其流动性是解决稠油开采、集输和炼制问题的关键。 China has a large reserves of heavy oil resources and a wide distribution of heavy oil bitumen resources. In order to meet the growing demand for energy from industrial and agricultural production, heavy oil increasingly attracts the attention of all countries. High density, high freezing point, viscosity, flow problems are prominent features of heavy oil resources in China. Therefore, to reduce the viscosity of heavy oil and improve its fluidity is the key to solve the problem of heavy oil recovery, gas gathering and refining.
