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。
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.
