Southwest Research Institute (SwRI) will open a new testing facility in April, offering standard corrosion testing for oil and gas clients. Located on the Institute’s San Antonio, Texas, campus, the facility will be used primarily to test the sulfide stress cracking resistance of carbon steel alloys for oil wells and offshore drilling applications.

西南研究院（SwRI）將于4月開設一個新的測試設施，為石油和天然氣客戶提供標準的腐蝕測試。該設施位于德克薩斯州 圣安東尼奧的校園研究所內，主要用于測試碳鋼合金在油井和海上鉆井應用中的抗硫化物應力開裂性。

“Previously, our laboratory work has been predominantly fit-for-purpose testing,” Elizabeth Trillo, one of the leaders of the project, said. “Those tests simulate an environment with specific solutions, temperatures, and pressures to evaluate materials used in specific drilling environments and determine whether they can withstand those conditions. Every test is different, but our specialty is catering to the client’s end-use need.”

該項目負責人之一Elizabeth Trillo表示：“以前，我們的實驗室工作主要是針對特定用途的測試。這些測試模擬特定環境中的溶液、溫度和壓力，以評估特定鉆井環境中使用的材料，并確定它們是否能在這些條件下使用。每項測試都是不同的，但我們專注于滿足客戶的最終用途需求。”

The goal of the facility is to provide cost-effective standardized testing as a part of SwRI’s comprehensive oil and gas sour corrosion testing portfolio.

作為SwRI綜合油氣酸腐蝕測試組合的一部分，該設施的最終目標是提供具有成本效益的標準化測試。

“Few industries operate under such harsh conditions,” Trillo said. “For this facility, we’ll mainly be looking at carbon steel materials used as casings in downhole drilling applications with high hydrogen sulfide levels.”

Trillo說：“很少有行業在如此高危的條件下從事測試工作，對于這一設施，我們將主要關注用作套管的碳鋼材料在高硫化氫環境下的井下鉆井應用。”

In drilling, the casing is a large pipe inserted into the earth to protect the equipment and support the wellstream. It is usually held in place with cement and endures massive amounts of pressure, high temperatures, and corrosive liquids. To withstand this environment, durable, lasting materials are necessary.

在鉆井過程中，套管是一根插入地下的大管子，用來保護設備和支撐井筒。通常用水泥加固，以承受巨大的壓力、高溫和腐蝕性液體。為了適應這種環境，必須選取一種耐用、持久的材料。

The National Association of Corrosion Engineers (NACE International) has developed particular tests and standards for materials used in the oil and gas industry. NACE standard test methodTM0177“Laboratory Testing of Metals for Resistance to Sulfide Stress Cracking and Stress Corrosion Cracking in H2S Environments” is widely used to qualify material performance in oilfield environments.

美國國家腐蝕工程師協會(NACE International)為石油和天然氣工業中使用的材料制定了特殊的測試和標準。NACE標準試驗方法TM0177《金屬在H2S環境中抗硫化物應力開裂和應力腐蝕開裂的實驗室試驗的標準測試方法》被廣泛用于評價油田環境中的材料性能。

“We’ve typically designed new test methods that give us flexibility and control over individual environmental parameters,” said James Dante, manager of SwRI’s Environmental Performance of Materials Section. “This new facility will provide us with the ability to perform repetitiveTM0177, NACE Atesting in a cost-effective and repeatable manner while providing our clients with the same level of service they have experienced with more complex testing.”

SwRI材料環境性能部門經理James Dante說:“我們經常設計新的測試方法，使得能夠靈活地控制各個環境參數。這個新設施將使我們能夠以經濟有效和可重復的方式重復執行TM0177，NACE A中的測試，同時為我們的客戶提供他們在更復雜環境測試中所得到的相同服務水平。”

SwRI is in the final stages of building the laboratory, which is dedicated to theNACE Astandard test method inTM017The facility will house multiple test cells allowing triplicate samples to be run on different materials. The proof ring cell assemblies are all housed within a customized glove box with nitrogen flow to ensure oxygen levels stay below 10 parts per billion.

SwRI實驗室正處于建設的最后階段，該實驗室致力于推動TM0177中的NACE A標準測試方法。該設施將包含多個測試單元，能夠一式三份地對不同材料進行測試。防爆環單元組件全部安裝在帶有氮氣流的定制手套箱內，以確保氧氣水平保持在十億分之十以下。

“Previously, a sample would be grouped with several others and might fail early on in a 30-day test,” Senior Engineering Technologist Steve Clay said. “That could be challenging, because there was no way to initiate new tests without disturbing the other samples still under test. One of the benefits of this new facility is we’re able to test samples in isolated test cells giving us the ability to change samples without disturbing other samples still under test.”

高級工程技術專家史蒂夫克萊說：“以前，一份樣本會與其他幾個樣本分組，并且可能在測試的前30天就已失敗。因為沒有辦法在不干擾其他仍在測試中的樣本的情況下啟動新的測試，此問題成為了一項挑戰。而新設備的好處之一是我們能夠在隔離的測試單元中測試樣品，并且能夠在不干擾仍在測試的其他樣品的情況下更換失敗樣品。“

As a matter of standard practice, the team will provide photographs of any cracks that occur during testing and will also report online environmental testing conditions including temperature and oxygen content.

作為行業標準，該團隊將會提供測試期間出現的任何應力開裂的照片以及包含溫度和氧含量等因素的在線測試報告。

（總結：高含硫環境測試一直是一項極度危險的測試工作，美國西南研究院新設施的建立無疑又推動了其在該領域內的領先地位，相比，我國在此技術方向仍然存在巨大的差距，還需加大技術引進及創新。）
