据油田技术5月4日消息，贝克休斯推出了一项新的海底井口技术，即MS-2环形密封件，通过减少钻机行程，帮助降低整体井口安装成本，从而节省大量的钻机运营成本。新的集成密封解决方案已在全球推出，并在休斯敦2022年海上技术会议上展出。该解决方案已被北美和南美的多个客户采用。
MS-2环形密封件是贝克休斯现有井口密封件MS-SN的最新技术开发，它增加了操作员对油井完整性的信心，并进一步延长了油井寿命。MS-2环形密封与现有的MS-800井口系统集成，有助于降低井的建设和干预成本，扩大干预选项，并确保在具有挑战性条件下油井的完整性和安全性。
贝克休斯油田设备执行副总裁Neil Saunders表示：“我们不断努力进行技术优化，并为我们的海底客户提供最先进的解决方案。通过我们新的MS-2环形密封件，我们正在帮助改变海底市场，并正在开发能够为海底客户提供长期价值、可靠性和效率的优质技术。”
MS-2可以在一次起下钻中安装，带有一个集成的锁环，无需第二次行程即可立即锁定高达200万磅的力，从而提高了钻机效率，节省了钻机时间。MS-2还可以更轻松地进入油井，无需额外的锁定装置。它经过20000psi和200次负载循环的测试，确保了现场寿命可靠性并进一步证明了密封的完整性。

Baker Hughes launches new subsea wellhead technology
Baker Hughes has launched a new subsea wellhead technology, the MS-2 Annulus Seal, to save substantial operational rig costs by helping lower overall wellhead installation costs due to reduced rig trips. The new integrated sealing solution, globally launched and exhibited at the 2022 Offshore Technology Conference in Houston, has already been adopted by multiple customers in North and South America.
The MS-2 Annulus Seal is the latest technological development to Baker Hughes’ existing wellhead seal, the MS-SN, which brings increased operator confidence in well integrity and further extends well life. The MS-2 Annulus Seal integrates with the existing MS-800 wellhead system and helps to lower the cost of well construction and intervention, expands intervention options, and ensures security and confidence of well integrity in challenging conditions.
Neil Saunders, executive vice president of Oilfield Equipment at Baker Hughes said: “We constantly strive for technological optimisation and delivering the most advanced solutions to our subsea customers. Through our new MS-2 Annulus Seal, we are helping to transform the subsea market and are developing quality technology that delivers long-term value, reliability and efficiencies for subsea customers.”
The MS-2 can be installed in a single trip, with an integrated lock ring that results in improved rig efficiency by providing immediate lockdown of up to 2 million pounds of force without the need for a second trip, saving rig time. The MS-2 also provides easier access to wells, with no need for supplemental lockdown devices. It is tested to 20,000 psi, and to 200 load cycles ensuring life-of-field reliability and further demonstrating the seal integrity.
