摘　　要：随着中轻质常规油资源的消耗，如何有效、经济地开采和利用非常规的重质油和沥青资源日益受到了人们的重视。本文首先对新疆超稠油的基本性质进行分析，然后考察其在50℃和常压的条件下，甲苯和汽油的掺入对超稠油降粘效果的影响，综合考虑稀油成本、减粘效果等因素，选择适当的掺油方式和比例混合掺入甲苯和汽油，并测试混合油的主要指标，以探索利用该超稠油制备船用燃料油的可能性。结果表明，掺入甲苯能够显著降低超稠油的粘度，而掺入汽油的降粘效果远不及掺入甲苯。在同样的掺稀比例下，先加甲苯后加汽油的降粘效果更好。通过采用混合掺入稀油（汽油和甲苯）对新疆超稠油进行降粘，所得混合油可达到180#和380#船用燃料油的大部分指标要求，具有一定的利润空间。With the gradual depletion of conventional light and medium oil resources, more attention has been focused on how to effectively and economically recover and utilize tremendous unconventional heavy oil and bitumen reserves. In this study the basic properties of a kind of super heavy oil from xinjiang （china） were determined firstly.Then the viscosity reduction experiments by blending toluene and gasoline were carried out at 50℃ and under the atmospheric pressure. Taking the cost of diluting solvents and the efficiency of reduction in viscosity into account,toluene and gasoline were mixed by an appropriate sequence and proportion to reduce the viscosity. The main indexes were tested to explore the possibility of producing fuel for ships from the super heavy oil by the blending diluting solvents technology. The results showed that the viscosity could be reduced remarkably by blending toluene,and the reduction in viscosity caused by blending gasoline was far from that caused by blending toluene. It was indicated that the sequence of blending different diluting solvents had an influence on viscosity reduction. Under the same proportion, blending toluene first and then gasoline was propitious to reduce the viscosity. By the application of blending diluting solvents technology, the viscosity of the super heavy oil was efficiently reduced and almost all the indexes of the obtained oil could meet the requirements of 180# and 380# fuel for ships, which might bring a biggish profits when being applied for commercial purpose.
