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。
This paper discusses the problems existing in the actual production of heavy oil wells in small fault blocks and analyzes the adaptability of the heavy oil viscosity reduction technology of power frequency electric heating rod, three-core heating cable and chemical viscosity reducer well that have been used in the field. Finally, combined with the specific conditions of heavy oil wells put forward in the future wellbore viscosity reduction can take technical measures.
