控压固井 (MPC) 已广泛应用于安装控压钻井 (MPD) 设备的钻井平台。这一发展源于作业者对 MPD 技术初始应用范围的挑战，该技术不仅适用于在狭窄的作业窗口内钻井（在许多情况下需要使用静态欠平衡泥浆重量），还适用于起下钻、测井、取芯和下套管，随后进行固井，并确保后续井段或仅仅是良好坐封的生产管柱所需的隔离。本文提供了深水钻井作业中主要和补救性 MPC 的规划和实施示例。
该项目在墨西哥湾钻探四口井，水深约5900英尺，总平均深度31000英尺（实测深度），采用第八代船型钻井平台进行钻探。
Managed pressure cementing (MPC) has been used in many applications where managed pressure drilling (MPD) equipment is installed on the rig. This development has been a consequence of operators challenging the initial scope of using MPD technology not only for drilling through a narrow operating window, in many cases by using a statically underbalanced mud weight, but also for tripping, logging, coring, and running casing, followed by cementing and guaranteeing the isolation required for a subsequent successful hole section or simply a well-set production tubular. The complete paper provides examples for planning and execution of primary and remedial MPC in deepwater drilling operations.
This project consisted of drilling four wells in the Gulf of Mexico with a water depth of approximately 5,900 ft and a total average depth of 31,000 ft measured depth. The wells were drilled with an eighth-generation ship-shaped drilling unit.
