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。
In view of the contradiction between the decrease of production and the increase of cost after the super-heavy oil well of Shu-1 area enters the high cycle, it is proposed that the intermittent throughput technology be used to improve the high cycle steam throughput. Through the analysis of the throughput mechanism and the actual statistics of the site, the conditions and effects of this technology are discussed. The results show that the technology is effective in high period wells and has a good promotion prospect.
