稠油在水蒸汽作用下组成变化研究
STUDY ON COMPOSITION CHANGES OF HEAVY OILS UNDER STEAM TREATMENT
摘要
Abstract
The aquathermolysis reaction of heavy oils obtained from Liaohe oil fields in China is studied at 240?℃.The results show that Liaohe heavy oils have been undergone visbreaking during the process. After treatment with steam, the viscosity of the heavy oil is reduced by 28%～42% and the amount of the saturate and aroomatic hydrocarbons is increased. The gas partition chromatography (GPC) results indicate that after reaction the accumulated amount of carbon numbers less than C25 is 50.97% in comparison with 17.93% before reaction. The results provided the basis data for recovery heavy oil by in-situ catalytic method in production heavy oil in oilfields.关键词
