如今,科学家与工程师们正在寻找各种制备纳米材料的方法,旨在充分利用纳米材料的优势性能,例如强度更高、重量更轻、光谱控制特性更强以及更好的化学反应活性。我希望了解一下纳米技术的应用。如何才能将纳米技术应用到当前的油气行业中,他会对生产效率产生什么影响?

纳米技术可以应用到任何方面,可以毫不夸张的说,能够限制纳米技术发展的只会是我们的想象力。可以想象出纳米技术在井控设备的智能零部件方面就有许多种应用方式,例如自恢复型闸板或者暴露到井眼中井控设备的表面反应性涂层,这些应用可以将设备的使用寿命大幅延长。
再比如纳米技术也可应用于液压设备的涂层,增强其防腐能力,并提高动密封的密封性能。纳米技术也可用于弹性材料,例如O型密封圈,它可以在压力和温度发生变化时改变自身特性从而防止液体漏失。总之,纳米技术的应用潜能是无限的。

目前石油行业内已经有许多纳米技术相关的研发应用工作正在进行。最近,我刚刚前读过一篇非常有意思的文章,讲的是人们研制出了一种可以生产薄膜和吸附剂的纳米管,来实现从石油中分离H2S 和 CO2的功能。休斯顿的莱斯大学正在研发一种纳米级陶粒支撑剂来替代传统的砂砾支撑剂,这种新型纳米级陶粒支撑剂能够有效地增大压裂半径。

Modumetal公司的Christina Lomasney曾发表过一篇关于将纳米材料应用到油气行业的文章。她在文章中提出了一种具有成本优势的纳米材料,这种材料通过提高抽油杆和其他井下设备的耐腐蚀能力和耐高温能力来降低油井的成本。此外,纳米材料应用到石油管材上,可以使其整体成本降低30%,并且更为轻薄的油管也提高了油井产量。
此外,文章中的其他内容也提到了可以将纳米技术用于微型传感装置进而来监控油藏情况,还研发出了一种可以对损坏部分进行检测并修复的“智能材料”,借助纳米技术的化学活性反应来预防支撑剂收到侵蚀。
Christina并不是唯一一个致力于将纳米技术应用到油气领域的人。我曾在2014年有幸采访过5名来自先进能源联盟的成员,该联盟是由来自30所大学的学者和来自世界上8家最大石油公司的专家所组成。先进能源联盟的主要工作是:使用电子传感器、化学反应制备的纳米材料和纳米尺度的造影剂来进行油气勘探工作、收集地质信息、绘制压裂缝网以及对注水开发情况进行监测。
Christina的文章中有一篇来自于叫做“Oceanit”工程公司的评论,这家公司开发的水泥能够检测井眼的完整性,一旦完整性受损,立即对作业人员发出警告。此外,他们还研发出了一种憎水性涂层,用以提高管道和井筒的抗腐蚀能力。
在同一篇文章中,堪萨斯大学三采项目实验室的主任Karen Peltier提出,纳米技术可用于制备表面活性剂涂层,该涂层可以在进入地层之前有效防止与外界发生化学反应。莱斯大学的Rafael Verduzco表示他们正努力研发耐高温的纳米颗粒表面活性剂和粘度增强剂。
一些应用可能在若干年后也会被淘汰,甚至有些设想可能永远无法实现。然而,我刚才谈到的这些人似乎都对将纳米技术应用到油气行业中充满热情。他们告诉我,先进能源联盟(AEC)正打算招募一批没有油气背景的纳米技术专家来为他们工作。

纳米技术可大幅提升润滑剂的性能。
Jason Johnson:
我同意Eric的观点,而且我希望能够进一步了解这方面的内容。我相信这会改变油气行业,润滑剂也同样如此。我也该做一下这方面的功课了。

纳米技术在降低成本以及增加产量方面具有很好的应用前景。

纳米技术可为油气行业提供一种涂层,这种涂层具有高结构强度、高防腐性能和高耐磨性能。Modumetal有限公司已经证实涂层应用到多种基材中后起到了很好的性能效果。
Len Bland:
我所在的Nano Gas Technologies公司,将纳米气泡运用到产出水中来进行原油分离并去除悬浮固体。我们在Permian盆地进行了现场试点,成功从采出水中分离出了所有7 mg/l以上的石油烃。
Ray Ozdemir:
新型纳米结构材料,例如金属-有机骨架结构物(MOFs)和多孔网络聚合物(PPNs),可用于气体的高容量储存或者具有高度选择性的气体分离。其中一个新兴的领域就是收集并储存火炬气,进而将废气转化为电能。火炬气可以储存在纳米结构材料中,由于这些材料储存容量大,其额定压力要远远低于压缩天然气的压力。
同传统的高比表面积材料相比,例如活性炭、沸石或者硅胶基质材料,纳米结构材料除了拥有高比表面积之外,能够有选择性的对指定气体进行收集。
金属-有机骨架结构物(MOFs)在空气和水中的耐久性较差,然而使用新型金属-有机骨架结构物(MOFs)的公司却很少遇到这些问题。这些都属于未来材料,并且许多专业化学公司正在积极地为此申请专利。如果想进一步了解这些材料的话,请谷歌搜索“MOFs & PPNs”或者同我联系,我非常乐意提供帮助。

Asked by Eric Medina :
Today’s scientists and engineers are finding a wide variety of ways to deliberately make materials at the nanoscale to take advantage of their enhanced properties such as higher strength, lighter weight, increased control of light spectrum, and greater chemical reactivity than their larger-scale counterparts. I want to know the applications for this technology. How can this technology apply to the current oil and gas technology and what efficiencies can become of this?
The answers:
Shaun Smithers:
The answer would appear to be almost any application – the limits would only be our imaginations! I for one could imagine numerous applications for the eventual use of this technology for smart components in well control equipment such as self-healing ram packers or well control equipment that have surfaces exposed to the well-bore coated in reactive coatings that could extend the life of the equipment far beyond its current limits. Or coatings on hydraulic equipment that are impervious to corrosion and have improved sealing capabilities with dynamic seals. Or elastomerics such as o-ring seals that can change properties when subjected to changes in pressure or temperature so that fluid leaks would be a thing of the past. There really is no limit to where this could go.
There is much R&D being conducted and funded for the application if Nanotechnology to the O&G industry. I recall reading a fascinating article very recently regarding research to produce membranes and adsorbents from nanotubes that could separate H2S and CO2 from oil. I believe Rice University right here in Houston is also conducting R&D on nanoparticles to create ceramic proppants as a replacement for sand proppants that would have the ability to push further into the reservoir. You may want to contact the Chemistry Dept. at Rice and ask who is heading this R&D up.
Greg Baehr:
Christina Lomasney of Modumetal Inc. has published an article on nanomaterials’ applications to oil and gas. Her piece argues that cost-competitive nanomaterials can improve well economics by allowing sucker rod strings and other downhole equipment to endure corrosive or high-temperature environments much longer. She adds that nanomaterials can reduce offshore OCTG costs as much as 30 percent and improve production by allowing operators to use lighter, thinner tubulars.
The remainder of her article looks at using tiny sensors to monitor reservoirs, creating ‘smart materials’ that can detect and repair damage, and deploying proppants that use nanochemical reactions to inhibit scale or corrosion.
Colter Cookson:
Christina is far from the only person advocating nanotechnology’s use in oil and gas. In 2014, I had the chance to interview five individuals with the Advanced Energy Consortium, a collaborative effort involving academics from 30 universities and professionals from eight of the world’s largest oil and gas companies. Much of AEC’s work focuses on using electronic sensors, chemically-reactive nanomaterials, and nanoscale contrast agents to determine where oil is, gather geological data, map fracture networks, and monitor waterfloods.
The article also includes comments from Oceanit, an engineering firm that has developed a cement capable of warning operators about wellbore integrity issues, as well as a water-repelling coating that can enhance the corrosion resistance of pipelines and downhole tubulars.
In the same article, Karen Peltier, the director of labs with the Tertiary Oil Recovery Program at the University of Kansas, discusses using nanotechnology to create coatings for surfactants that will keep them from reacting until they enter the formation. Rafael Verduzco of Rice University describes efforts to develop nanoparticle surfactants and viscosity enhancers that can withstand high temperatures.
Many of these applications may be years away, and some of them may never materialize. However, the people I talked to seemed passionate about applying nanotechnology to oil and gas. They also told me that the AEC is doing a great job of getting nanotechnology experts with no oil and gas background to work in the industry.
Mohand Melbouci:
Lubrication would be greatly enhanced with nanotech.
Jason Johnson:
I agree Eric. I would like to learn more. I believe it can change the industry in fluids technology, and lubricants also. Might have to take some classes on this.
Mark Van Velzor:
Interesting opportunities especially those that reduce cost and increase production.
Timm Burnett:
Nano technology can provide coatings that will provide structural strength, corrosion resistant and wear resistant properties for the oil and gas industry. Through Nano layering Modumetal Inc. has demonstrated that coatings applied to many different types of substrates can achieve higher levels of performance.

My company, Nano Gas Technologies, uses nano scale bubbles of gas in produced water to separate oil and remove suspended solids. We have a demonstration site in the Permian where we have recovered all but insignificant amounts (less than 7 mg/l) of TPH in the water.
Ray Ozdemir:
Novel nanostructured materials such as metal-organic frameworks (MOFs) and porous polymer networks (PPNs) can be used for high capacity gas storage and (highly selective) gas separation. One emerging area is flare gas capture and storage for waste-to-power conversion. Intermittent and continuous flare gas could be stored in nanostructured materials at significantly less pressures compared to CNG since these materials offer high storage capacities. Nanostructured means that they have high surface areas and they can be ‘designed’ to selectively capture targeted species unlike conventional high surface area materials like activated carbons, zeolites or silica-based materials. MOFs have suffered durability issues in air and water but there are few companies with novel MOFs which have overcome this problem. These are the materials of the future and a lot of specialty chemicals companies are actively patenting the IP space, just Google ‘MOFs and PPNs’ to learn more or contact me, I would be more than happy to help.
