井筒防蜡技术的研究

Study on the Paraffin Inhibition Technology of Well Bore

井筒防蜡技术不仅直接影响油井的采收率和抗负荷能力,而且对油田的稳定生产也有重要的影响。简要介绍了井筒的结蜡机理及其主要影响因素,此外,分别从物理、化学及生物技术等角度系统阐述了典型防蜡技术的方法以及优缺点,在此基础上,探讨了防蜡技术的最新研究进展并指出了今后的发展趋势。

The paraffin inhibition technology of well bore not only affects the recovery ratio and the load capacity of the oil well, but also has an important influence on the stable production of oil field. In this paper, mechanism and main influence factors of well bore wax precipitation were briefly introduced. In addition, typical paraffin inhibition technologies as well as their advantages and disadvantages were systematically analyzed from physical, chemical and biological technology aspects. On the basis of this, the latest research progress of the paraffin inhibition technology was discussed, and the future development direction of the paraffin inhibition technology was pointed out.
