曙一区超稠油间歇蒸汽吞吐技术探讨

Intermittent cyclic steam stimulation in super heavy oil producer of Shul area

针对曙一区超稠油井进入高周期后产量递减、成本上升的矛盾,提出用间歇吞吐技术改善高周期蒸汽吞吐效果。通过对吞吐机理和现场实际资料统计的分析,对这项技术实施的条件及效果进行了探讨,结果表明,该项技术在高周期井实施效果较好,具有较好的推广前景。

After super heavy oil producers in Shul area entered latter cycles of steam stimulation, oil production decreased , costs increased. Intermittent cyclic steam stimulation was put forward to improve the effectiveness of steam stimulation in latter cycles. Through analyzing steam stimulation mechanism and field data, this paper discusses the operation conditions and effectiveness of this method. Good result has been achieved after applying this technique in producers during latter cycles. This technique has a bright future of spreading.
