- Abstract
With the decline of international crude oil price, the previous petroleum-based oil-displacing agent( NB-5034A) is difficult to be applied in oil field because of its high cost. To solve this problem, the low cost lignin-based self-emulsification oildisplacing agent was studied. First, according to the characteristics of Linpan heavy oil, the formula of lignin-based self-emulsification oil-displacing agent (NB-50PA) was optimized in the lab; then the effects of concentration, temperature, displacement velocity and mode, rock properties and oil viscosity on oil recovery were evaluated using simulation tests; the application conditions of NB-50PA for Linpan heavy oil were obtained. According to the field experiment, NB-50PA can increase the average recovery of Linpan heavy oil by 24.51%, and the cost is only 1/3 of the previous petroleum-based self-emulsification oil-displacing agent.
