MPas mechanical packer

Ensure a quality cement job and protect sensitive formations with theMPas™ mechanical packerfrom 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.

Assured sealing for the life of the packer

海洋保护区机械封隔器有一个弹性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 hydrostatic pressure will continue to apply a setting force on the element throughout the life of the packer, which will compensate for any formation movement and will allow for additional setting force to be applied at any time. Additional setting force can be attained by applying additional pressure with a cup tool or by applying pressure to the entire casing string, if applicable.

The MPas packer is normally run in the liner string between screens, slotted casing, or gravel packed sections as a means to isolate production intervals. You can also use the packer to isolate the open hole/liner annulus in openhole completions in conjunction with stage cementing equipment. And for your deep wells requiring stage cementing, the MPas packer can protect lower zones from the high differential pressure of a long column of cement.
