| 摘 要： | 胜利油田稠油及超稠油开采主要以蒸汽吞吐为主，不同油田均存在注汽压力高、注汽干度低、吞吐后采收率低等现象，而油水之间的界面张力是影响开发的主要因素。针对这一问题，应用由胜利原料油制备出具有复杂结构的阴离子石油磺酸盐体系，提高了稠油油藏开采效果。通过确定磺酸盐体系的构成，以及对其成品耐温抗盐性能评价，表明该磺酸盐体系能够较好适应单家寺油田的开发需要，耐温抗盐性能均能达到生产要求。通过高温岩心驱替实验得出石油磺酸盐体系能够有效降低注蒸汽压力和岩心采收率。单家寺油田现场试验5口井，平均增油量8．5t·d^-1，油汽比上升0.311，效果较好。 |

| Abstract: | Steam stimulation is the key development method of heavy oil and super-heavy oil development in Shengli Oilfield.Yet the disadvantages of such a method is obvious with high steam injecting pressure,low steam volume fraction,low recovery efficiency after the stimulation.The interfacial tension between oil and water is the key influencing factor that affects the recovery efficiency.The mahogany sulfonate made from stock oil of Shengli Oilfield is applied to the EOR operation of heavy oil reservoir,which is a ... |
