石油设备网讯 据世界能源网2019年3月25日休斯顿报道，挪威能源研究咨询公司雷斯塔能源（Rystad Energy）日前在一份报告中说，美国本土陆上水平再压裂市场在最近几年里出现了蓬勃发展，在过去10年里，水平再压裂作业每年都在增加。
根据雷斯塔能源公司公布的最新统计数据，美国在2009年只有不到10口井实施了重新压裂作业，但这个数字到2018年激增至550多口井。
美国2018年重新压裂井的新统计数据仍处于初步阶段，一些报告显示，美国去年第四季度的压裂作业出现了延迟。然而，雷斯塔能源公司的初步分析揭示了一些关于重新压裂状态的全新见解。
其中一个关键结论是，尽管美国重新压裂井的数量有所增加，但是与原始完井市场相比，水平重新压裂市场的相对规模在2016年经济衰退时期达到了5.3%的峰值，而去年下降到了3.8%。
许多业内专家认为，由于重新压裂技术仍然相对不成熟，这种下降趋势可能会持续下去，与加密井钻井相比，其结果的可预测性更低。由于这种技术障碍，降低间隔子井项目往往优先于母井重新压裂。

US Re-fracking Balloons to 550 Wells
The horizontal re-frac market within the US onshore scene has boomed in the recent years, with the number of horizontal re-frac jobs increasing every year over the last 10 years, said a report.
According to Rystad Energy, the energy research and business intelligence company, in 2009, fewer than 10 wells were re-fracked, but in 2018 that number ballooned to more than 550 wells.
New 2018 data is still preliminary amid some reporting delays for frac jobs in the fourth quarter of 2018. However Rystad Energy’s initial analysis reveals some interesting insights regarding the state of re-fracking.
One key takeaway is that, despite an increase in the number of re-fracked wells, the relative size of the horizontal re-frac market, compared to the original completion market, peaked during the downturn in 2016 at 5.3%, and declined to 3.8% last year.
Many industry experts argue that this decline may persist, as re-frac technologies remain relatively immature, delivering less predictable results compared to infill well drilling. Because of this technological barrier, down-spacing child projects are often prioritized over parent well re-fracs.
