摘要：

稠油热采对完井设计提出了特殊的要求.结合渤海某稠油油田的实践经验,指出了稠油热采完井设计的技术热点,建立了热采井井筒温度剖面分析模型和生产管柱热载荷伸长量的计算方法.分析了不同注热温度和油管保温措施对注热效果的影响,对注热造成的油管,筛管伸长进行了评估,为完井管柱设计采取相关的技术措施提供定量参考.通过算例表明采用保温措施能大大改善注热效果,尤其是在注热温度较高的情况下,保温措施能显著降低沿程热量损失;采用具有低传热保温效果的管柱,可以缓解伸长量增加对井口预留空间的需求.

Abstract:

Completion design for thermal recovery heavy oil well is different from that for normal well. According to experiences on development of heavy oil well in Bohai Bay, key technical poitns of completion design for thermal recovery heavy oil well are summarized, and analysis models of wellbore temperature profiles and working string thermal load are established. Effects of thermal injection and thermal extension of working string are evaluated, including sensitivity analysis on injection temperature and insulation measures. The results of an example shows that insulation measures can considerably lower the thermal loss along the path and the demand of reserved space in wellhead, especially at high injection temperature.

Key words: thermal recovery of heavy oil, well completion design, sand control, temperature profile, thermal load
