如今,科學家與工程師們正在尋找各種制備納米材料的方法,旨在充分利用納米材料的優勢性能,例如強度更高、重量更輕、光譜控制特性更強以及更好的化學反應活性。我希望了解一下納米技術的應用。如何才能將納米技術應用到當前的油氣行業中,他會對生產效率產生什么影響?
看看下面這些人的回答

納米技術可以應用到任何方面,可以毫不夸張的說,能夠限制納米技術發展的只會是我們的想象力??梢韵胂蟪黾{米技術在井控設備的智能零部件方面就有許多種應用方式,例如自恢復型閘板或者暴露到井眼中井控設備的表面反應性涂層,這些應用可以將設備的使用壽命大幅延長。
再比如納米技術也可應用于液壓設備的涂層,增強其防腐能力,并提高動密封的密封性能。納米技術也可用于彈性材料,例如O型密封圈,它可以在壓力和溫度發生變化時改變自身特性從而防止液體漏失??傊?,納米技術的應用潛能是無限的。

目前石油行業內已經有許多納米技術相關的研發應用工作正在進行。最近,我剛剛前讀過一篇非常有意思的文章,講的是人們研制出了一種可以生產薄膜和吸附劑的納米管,來實現從石油中分離H2S 和 CO2的功能。休斯頓的萊斯大學正在研發一種納米級陶粒支撐劑來替代傳統的砂礫支撐劑,這種新型納米級陶粒支撐劑能夠有效地增大壓裂半徑。

Modumetal公司的Christina Lomasney曾發表過一篇關于將納米材料應用到油氣行業的文章。她在文章中提出了一種具有成本優勢的納米材料,這種材料通過提高抽油桿和其他井下設備的耐腐蝕能力和耐高溫能力來降低油井的成本。此外,納米材料應用到石油管材上,可以使其整體成本降低30%,并且更為輕薄的油管也提高了油井產量。
此外,文章中的其他內容也提到了可以將納米技術用于微型傳感裝置進而來監控油藏情況,還研發出了一種可以對損壞部分進行檢測并修復的“智能材料”,借助納米技術的化學活性反應來預防支撐劑收到侵蝕。
Christina并不是唯一一個致力于將納米技術應用到油氣領域的人。我曾在2014年有幸采訪過5名來自先進能源聯盟的成員,該聯盟是由來自30所大學的學者和來自世界上8家最大石油公司的專家所組成。先進能源聯盟的主要工作是:使用電子傳感器、化學反應制備的納米材料和納米尺度的造影劑來進行油氣勘探工作、收集地質信息、繪制壓裂縫網以及對注水開發情況進行監測。
Christina的文章中有一篇來自于叫做“Oceanit”工程公司的評論,這家公司開發的水泥能夠檢測井眼的完整性,一旦完整性受損,立即對作業人員發出警告。此外,他們還研發出了一種憎水性涂層,用以提高管道和井筒的抗腐蝕能力。
在同一篇文章中,堪薩斯大學三采項目實驗室的主任Karen Peltier提出,納米技術可用于制備表面活性劑涂層,該涂層可以在進入地層之前有效防止與外界發生化學反應。萊斯大學的Rafael Verduzco表示他們正努力研發耐高溫的納米顆粒表面活性劑和粘度增強劑。
一些應用可能在若干年后也會被淘汰,甚至有些設想可能永遠無法實現。然而,我剛才談到的這些人似乎都對將納米技術應用到油氣行業中充滿熱情。他們告訴我,先進能源聯盟(AEC)正打算招募一批沒有油氣背景的納米技術專家來為他們工作。

納米技術可大幅提升潤滑劑的性能。
Jason Johnson:
我同意Eric的觀點,而且我希望能夠進一步了解這方面的內容。我相信這會改變油氣行業,潤滑劑也同樣如此。我也該做一下這方面的功課了。

納米技術在降低成本以及增加產量方面具有很好的應用前景。
Timm Burnett:石油圈原創www.h29736.cn
納米技術可為油氣行業提供一種涂層,這種涂層具有高結構強度、高防腐性能和高耐磨性能。Modumetal有限公司已經證實涂層應用到多種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,將納米氣泡運用到產出水中來進行原油分離并去除懸浮固體。我們在Permian盆地進行了現場試點,成功從采出水中分離出了所有7 mg/l以上的石油烴。
Ray Ozdemir:
新型納米結構材料,例如金屬-有機骨架結構物(MOFs)和多孔網絡聚合物(PPNs),可用于氣體的高容量儲存或者具有高度選擇性的氣體分離。其中一個新興的領域就是收集并儲存火炬氣,進而將廢氣轉化為電能?;鹁鏆饪梢詢Υ嬖诩{米結構材料中,由于這些材料儲存容量大,其額定壓力要遠遠低于壓縮天然氣的壓力。
同傳統的高比表面積材料相比,例如活性炭、沸石或者硅膠基質材料,納米結構材料除了擁有高比表面積之外,能夠有選擇性的對指定氣體進行收集。
金屬-有機骨架結構物(MOFs)在空氣和水中的耐久性較差,然而使用新型金屬-有機骨架結構物(MOFs)的公司卻很少遇到這些問題。這些都屬于未來材料,并且許多專業化學公司正在積極地為此申請專利。如果想進一步了解這些材料的話,請谷歌搜索“MOFs & PPNs”或者同我聯系,我非常樂意提供幫助。

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.
