A Study On The Comprehensive Utilization Of Heavy Crude Oil Of Daqing Peripheral Oilfields

The object of this thesis is to roundly analyse the heavy oil of Heidi temple heavy oil exploitationtechnology limited company, which is joint-stock of nanyuan stock company and Daqing oil field liabilitycompany. We discussed that the production project of making use of heavy oil to yield asphaltum andSurfactants and probe into the heavy oilof Daqing Peripheral Oilfields, whether or not it suit to produce theasphaltum and Surfactants, we studied the production technology of the asphaltum and Surfactants.After the analysis of the heavy oil, it indicates that the heavy oil has lofty saturation and low aromacomponent and asphaltum, lofty wax and low extended performance. Daqing Peripheral Oilfields aredifficult to pass routine process technology, which is accord with roadway and asphaltum products of ourcountry ministry of communications standard. According to the solvent pulling off asphaltumexperimentation, it can find that the heavy oil contains much asphaltum component. So the heavy oil ofDaqing Peripheral Oilfields don not adapt to produce the asphaltum and Surfactants. However, it can makeit turn into raw materical of reducing viscidity and retarding coking.According to the characteristics of Daqing Peripheral heavy oil, we empolder bright oil and confirm thattechnology project and technologycondition of bright oil, diesel oil and fuel oil.
