摘要
Abstract
Tahe light oil,catalytic cracking diesel,polymethoxy-dimethyl ether,and homemade agent SW-1 were used to dilute and reduce the viscosity of Tahe super heavy oil.The viscosity reduction effect of different dilute media was evaluated.The production process was put forward for green super heavy oil to dilute and reduce viscosity.The viscosity reduction effect of SW-1 super heavy oil was investigated.The results indicate that the effectiveness of the four dilute media in reducing the viscosity of Tahe super heavy oil is ranked as follows:home made agent SW-1＞polyoxymethylene-di methyl ethers＞light cycle oil＞Tahe light oil;SW-1 can be fully recovered in the water phase,and its recovery rate in the oil phase can reach 99.50％when the dilution ratio is 0.070;under the conditions of a single well liquid production rate of 100 m3/d and a 30％(w)water content of super heavy oil,the super heavy oil production can be increased by 62.61％using SW-1 for dilution and viscosity reduction,thus replacing 13 290.6 t/a of Tahe light oil.This significantly improves the super heavy oil production and economic benefits of the oilfield,providing a new technical approach for the green and efficient dilution and extraction of heavy oil.关键词
