石油设备网讯 据今日油价网站3月11日消息 英国陆上石油天然气工业集团（UKOOG）周一在一份报告中称，如果英国在页岩气储量上开展水力压裂技术，到20世纪30年代初，几乎可以消除净天然气进口。
在英国Cuadrilla公司最近的流量测试数据公布后，该集团修改了其对潜在份额天然气产量的估计。Cuadrilla去年在英格兰恢复了水力压裂作业，这是七年来的首次。
根据UKOOG的说法，Cuadrilla公司在兰开夏郡Preston New Road(PNR)现场的初始流量测试“扩大至整个页岩层，所有阶段都进行有效地水力压裂，这能够增加以前对岩层产量的估计。
UKOOG估计，在全国范围内推出100台含40个侧翼的水力压裂设备（共4000个侧翼），将使英国的年产量在20世纪30年代初达到近1400亿立方英尺的峰值，相当于3500万户家庭的用气量，超过英国的总用气量。该行业组织称，该国的天然气净进口量在20世纪30年代初几乎可以消除，每年将国际收支平衡提高约104亿美元（80亿英镑）。
目前，英国的天然气产量足以满足44%的需求，而47%的天然气是通过挪威和欧洲的管道进口的，另外9%则是液化天然气。
由于北海的产量预计在未来几年和几十年内会下降，估计表明英国将越来越依赖天然气进口。
然而，英国的水力压裂受到了环保人士的强烈反对，英国有严格的震颤限制规定，如果里氏震级为0.50级或更高的微地震事件发生，需要暂停作业。
Cuadrilla上个月称，在英格兰西北部的压裂现场进行的初步流量测试表明，该地区有一个储量丰富、可采天然气的高质量储层，同时它还要求放宽震颤界限的规定，以便进行适当的评估，但该公司不得不多次停止运营，因为测量值高于临界值的微地震事件需要停止作业。

Fracking Could Help UK Eliminate Gas imports By 2030s
If the UK were to roll out fracking at its shale gas reserves, it could nearly eliminate its net gas imports by the early 2030s, industry group United Kingdom onshore Oil and Gas (UKOOG) said in a report on Monday.
The group has revised up its estimates for potential share gas production, after the recent flow test data from UK company Cuadrilla, which resumed fracking in Englandlast year for the first time in seven years.
According to UKOOG, the initial flow test at Cuadrilla’s Preston New Road (PNR) site in Lancashire “scaled up for a full-length lateral with all stages effectively hydraulically fractured, allows us to increase our previous estimates of production from each lateral.”
UKOOG has estimated that a national roll-out of 100 pads of 40 laterals (4,000 laterals in total) would lead to the UK’s annual production peaking at almost 1,400 bcf in the early 2030s, which is equivalent to the gas use of 35 million homes, more than the UK total. The country’s net gas imports could be almost eliminated in the early 2030s, improving the balance of payments by around US$10.4 billion (£8 billion) a year, the industry group said.
At present, the UK currently produces enough gas to meet 44 percent of its needs, while it imports 47 percent of its gas via pipelines from Norway and Europe, and another 9 percent in the form of liquefied natural gas (LNG).
As production in the North Sea is expected to decline over the coming years and decades, estimates point to the UK becoming increasingly dependent on natural gas imports.
Fracking in the UK, however, is met with fierce opposition from environmentalists, and the UK has strict tremor limits regulations that require pausing operations in case of micro seismic events of 0.50 on the Richter scale or higher.
Cuadrilla said last month that initial flow tests at its fracking site in northwest England showed a rich reservoir with high-quality recoverable natural gas, while it also called for the rules on tremor limits to be eased so proper appraisals could be made. The company has had to stop operations multiple times, due to micro seismic events measuring above the threshold requiring a halt.
