Saint-Gobain Seals has been selected by a major U.S.油和气公司有资格的荧光素®sealing solutions and polymer materials to enhance oil recovery for an ultra-high pressure field in the Gulf of Mexico, contributing chemical compatibility tests with requirements for 20,000 psi pressure (20K) valve qualification. Purpose of the testing will assess the suitability of non-metallic sealing materials in specific stimulation hydrofluoric acid fluid mixtures representative of the composition commonly used in the Gulf area.
Offshore production in the Gulf accounts for 17 percent of total U.S. crude oil output, according to the U.S. Energy Information Administration, and major offshore producers include Shell, Anadarko, BP and Chevron. Saint-Gobain Seals was asked to partner on the Gulf project due to their decades of experience in designing engineered sealing systems such asOmniSeal®spring-energized sealsfor临界阀茎and heavy R&D investment such as theirKontich实验室扩展, related to high pressure and high temperature (HPHT) conditions where pressure rating is greater than 15,000 psi and/or temperature rating is greater than 350°F (177°C).
测试程序包括老化材料样品和在20,000 PSI压力下的氢氟酸混合物中完整的密封堆组成，并在300°F（149°C）的温度下进行160小时。进行了物质的物理特性测量，以说明暴露前后负载下的拉伸，硬度，质量，密度，体积和变形的变化。官方通行证和失败标准至少基于NORSOK M-710版，第3版标准，该标准定义了关键的非金属密封，座椅和备用材料，以永久使用，包括井完成，包括井完成，亚博网站下载X-MAS树，控制系统和阀门以及关键气体系统中的顶部阀。
Carried out by a third party laboratory, the complete immersion test campaign resulted in the confirmation of each of the four Saint-Gobain Seals’ Fluoroloy® materials meeting the requirements of NORSOK M-710, edition 3 standard after hydrofluoric acid fluid exposure up to 300°F (149°C) temperature. In addition to these polymer materials being qualified in high pressure, high temperature and corrosive conditions, the measured physical properties after exposure will help to build degraded material models to conduct design assessment simulation on custom-designed seal stacks using Saint-Gobain Seals’ internal finite element analysis capabilities. Their Fluoroloy®as well as theirMeldin®亚博网站下载have also beenapproved for API 6A specification（ISO 10423，附录F.1.13.5.2）与酸（FF/HH）电阻有关。
Aside from Fluoroloy®经过评估的化合物，根据相同的程序，以应对阀供应商使用的硬件，根据相同的程序将几组圣菜密封件的定制密封堆栈老化。该项目的选定的Topside和Subsea 20,000 PSI阀供应商将对STEM窃取模型中的老年密封堆栈进行周期性测试。模拟测试应符合API 6A，附件F，设计验证测试的测试程序。模拟测试的一个关键好处是在阀供应商开始在实际阀门上开始完整的API 6A PR2资格之前预验证。
预计墨西哥湾的生产预计将在2019年达到创纪录的水平，这是由于壳牌股份（Shell Appomatox）等几个项目的推动。此外，根据分析师韦斯特伍德（Westwood）的说法，今年有90个潜在的深水最终投资决策继续改善前景。BP最近对亚特兰蒂斯第三阶段发展的最终投资决定以及雪佛龙锚定超高压力领域的预期最终投资决定来说明这一点。随着这种增长，需要新技术，例如密封解决方案，特别是针对近期开发探索的高压水库。
