據油田技術5月4日消息，貝克休斯推出了一項新的海底井口技術，即MS-2環形密封件，通過減少鉆機行程，幫助降低整體井口安裝成本，從而節省大量的鉆機運營成本。新的集成密封解決方案已在全球推出，并在休斯敦2022年海上技術會議上展出。該解決方案已被北美和南美的多個客戶采用。

MS-2環形密封件是貝克休斯現有井口密封件MS-SN的最新技術開發，它增加了操作員對油井完整性的信心，并進一步延長了油井壽命。MS-2環形密封與現有的MS-800井口系統集成，有助于降低井的建設和干預成本，擴大干預選項，并確保在具有挑戰性條件下油井的完整性和安全性。

貝克休斯油田設備執行副總裁Neil Saunders表示：“我們不斷努力進行技術優化，并為我們的海底客戶提供最先進的解決方案。通過我們新的MS-2環形密封件，我們正在幫助改變海底市場，并正在開發能夠為海底客戶提供長期價值、可靠性和效率的優質技術?！?/p>

MS-2可以在一次起下鉆中安裝，帶有一個集成的鎖環，無需第二次行程即可立即鎖定高達200萬磅的力，從而提高了鉆機效率，節省了鉆機時間。MS-2還可以更輕松地進入油井，無需額外的鎖定裝置。它經過20000psi和200次負載循環的測試，確保了現場壽命可靠性并進一步證明了密封的完整性。

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.
