摘要:

随着国际原油价格的下降,前期研制的石油基自乳化驱油剂(NB-5034A)因为成本问题,难以继续在实际生产中应用。针对这一问题,开展了低成本木质素基自乳化驱油剂的研究。首先针对临盘稠油特点,优化得到了合适的木质素基自乳化驱油剂配方(NB-50PA);然后通过物模实验,研究了驱油剂浓度、实验温度、驱替速度与方式、岩心性质和稠油黏度等因素对采收率的影响,评估了NB-50PA的使用条件。现场试验表明,NB-50PA可使临盘稠油的平均采收率提高24.51%,并且成本仅为前期研制的石油基自乳化驱油剂的1/3。

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 oil-displacing 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.

Key words: Linpan heavy oil, lignin-based, self-emulsification, oil-displacing agent, field experiment
