威德福國(guó)際公司周四報(bào)道稱(chēng)，該公司已與埃尼公司簽署了一份為期四年的獨(dú)家合同，為其提供配備無(wú)線電頻率識(shí)別的井下套管隔離閥。

威德福在發(fā)給鉆井的電子郵件中指出，該合同要求在關(guān)鍵的埃尼井中部署至少30個(gè)無(wú)臍帶井下部署閥(NU-DDV)。

威德福鉆井、評(píng)估和干預(yù)部門(mén)總裁Dean Bell表示:“該合同與威瑟福德和埃尼公司從開(kāi)始到結(jié)束鉆井和完井過(guò)程中持續(xù)改善作業(yè)安全和環(huán)境性能的努力是一致的?！?/span>

威德福表示，在管理壓力鉆井(MPD)和欠平衡鉆井(UBD)應(yīng)用中，配備射頻識(shí)別設(shè)備(RFID)的閥門(mén)通過(guò)在起下鉆過(guò)程中機(jī)械地將儲(chǔ)層與地面隔離，從而提高了過(guò)程安全性，并且無(wú)需壓井。此外，該公司還聲稱(chēng)，這種閥門(mén)減少了外部控制線和夾緊操作，縮短了安裝時(shí)間，將人員從紅區(qū)撤離，消除了抽油效果，并縮短了脫扣時(shí)間，從而提高了系統(tǒng)的可靠性。

貝爾繼續(xù)說(shuō)道:“該獎(jiǎng)項(xiàng)是與埃尼公司兩年研發(fā)合作的成果，該公司推出了一款帶RFID的井下套管隔離閥?！薄拔覀兊哪繕?biāo)是開(kāi)發(fā)一種創(chuàng)新的解決方案，能夠提供一種獨(dú)立的井下安全防護(hù)層，作為現(xiàn)有常規(guī)防護(hù)層的補(bǔ)充，確保在下鉆時(shí)控制不合理的地層涌入?！?/span>

Weatherford Secures Four-year Eni Contract

Weatherford International reported Thursday that it has signed an exclusive four-year contract with Eni S.p.A. for radio frequency identification-equipped downhole casing isolation valves.

The contract calls for at least 30 Non-Umbilical Downhole Deployment Valves (NU-DDV) that will be deployed in critical Eni wells, Weatherford noted in a written statement emailed to Rigzone.

“This contract aligns with both the Weatherford and Eni pursuit of continuous improvement in operational safety and environmental performance across the start-to-finish drilling and completion process,” remarked Dean Bell, Weatherford’s president for drilling, evaluation and intervention.

Deployed during managed pressure drilling (MPD) and underbalanced drilling (UBD) applications, the radio frequency identification device (RFID)-enabled valve enhances process safety by mechanically isolating the surface from the reservoir during tripping and eliminates the need to kill the well, Weatherford stated. Also, the company contends the valve boosts system reliability by eliminating external control line and clamping operations, cuts installation time, removes personnel from the red zone, eliminates swabbing effects and reduces tripping time.

“This award is the result of two years of research and development collaboration with Eni to launch a downhole casing isolation valve with RFID,” continued Bell. “The goal was to develop an innovative solution capable of providing an independent downhole safety barrier to supplement the conventional barriers already in place, assuring control of unwarranted formation influx while tripping.”
