概述
Ensure a quality cement job and protect sensitive formations with theMPAS™机械包装器from Baker Hughes. A primary cementing and zone isolation packer, the MPas packer uses a noninflatable packing element run as an integral part of the casing string to provide a robust, permanent seal between the casing and wellbore.
保证包装工的寿命
The MPas mechanical packer has an elastomeric element with composite structure, which is set mechanically by shifting a balance sleeve. This allows wellbore hydrostatic pressure to act against an atmospheric chamber and apply a setting force to the noninflatable element. The element is then mechanically locked, which eliminates the requirement of the wellbore fluid to maintain the set.
Wellbore静水压力将继续在包装工的整个寿命中对元素施加固定力，这将补偿任何地层运动，并将允许随时施加额外的设置力。如果适用，可以通过使用杯子工具施加额外的压力或向整个外壳绳施加压力来实现其他设置力。
MPA包装器通常在屏幕，开槽外壳或砾石包装的截面之间的衬里字符串中运行，以隔离生产间隔。您还可以使用包装器与舞台胶结设备结合使用打开孔完成的开孔/衬里环。对于需要阶段胶结的深井，MPAS包装器可以保护下区域免受长列水泥的高差压力。
