休斯顿–  Dril-Quip 为巴西桑托斯盆地近海 Aram 区块的 Petrobras 勘探项目安装了 18 3/4 英寸 BigBore IIe，这是其最新的海底井口系统。

水深2,002米。

据 Dril-Quip 称，该系统的密封技术符合最新的巴西国家石油公司标准。它的设计目的是通过无需钻井或生产锁定装置来降低成本，从而限制与钻井相关的起下钻次数。

该技术已经过超过 9000 万次弯曲循环的疲劳测试，具有 2 MMlb 的气密吊架锁定能力，可抵抗热负荷和压力负荷。

BigBore IIe 的压力容量为 15,000 psi/27 英寸 (SS15) 和 20,000 psi/30 英寸。(SS20)，并且可以提供传统配置文件或公司的 DXe 锁定配置文件。

16英寸和18英寸套管、套管悬挂器和密封组件均可穿过21英寸外径钻井隔水管、18-3/4英寸防喷器组和井口外壳。

HOUSTON — Dril-Quip has installed an 18 ¾-inch BigBore IIe, its newest subsea wellhead system, for the Petrobras Exploratory project in the Aram Block in the Santos Basin offshore Brazil.

Water depth is 2,002 m.

According to Dril-Quip, the system’s sealing technology is qualified to the latest Petrobras standards. It is designed to reduce costs through dispensing with the need for drilling or production lockdown devices, which in turn limits the number of trips associated with drilling the well.

The technology has been fatigue tested to more than 90 million bending cycles with 2 MMlb of gas-tight hanger lockdown capacity to resist thermal and pressure loads.

BigBore IIe comes in pressure capacities of 15,000 psi/27-inch (SS15) and 20,000 psi/30-in. (SS20), and it can be supplied with legacy profiles or the company’s DXe locking profile.

Both 16-inch and 18-inch casing, casing hangers and seal assemblies can pass through the 21-inch OD drilling riser, 18-3/4-inch BOP stack and the wellhead housing.
