摘要

本文讨论了小断块稠油井实际生产中存在的问题,并对现场已经采用的工频电热杆、三芯加热电缆及化学降粘剂井筒稠油降粘技术进行了适应性分析。最后结合稠油井具体情况提出了今后井筒降粘可采取的技术措施。

Abstract

This paper discusses the existing problems in the production of viscous oil wells in craven fault oilfield,gives a suitability analysis to the viscosity-reduction techniques used in viscous oil wells such as power frequency electrothermal rod,three-core heating cable and chemical viscosity-reducing agent,and then presents the adoptable technical measures for the viscosity-reduction of viscous oil in combination with concrete conditions of high-viscosity wells.
