Application researches on the CDJZ heavy oil viscosity reducer in Jilin Oilfield

In this paper,it is reported that in light of the characteristic of heavy oil in Jilin oilfield,the application researches of CDJZ heavy oil viscosity reducer have been carried out in the experimental room and the field test. The results shown that the maximum reducing rate could obtain up to 99%,the picking oil rate could raise markedly,thus it could decrease greatly the producing cost and obtain a good economic and society benefits. In addition,the reducing viscosity mechanism was also discussed preliminarily
