发明名称 HIGH PRESSURE/HIGH TEMPERATURE PACKER SEAL
摘要 A packer device includes an elastomeric packer element which is seated upon an inner sleeve that surrounds a central inner mandrel. The inner sleeve and the inner mandrel are oriented at an angle of departure with respect to the central axis of the tool, thereby providing a ramp assembly which helps to set the packer device. An anchor ring and a retaining ring are located on opposite axial sides of the packer element and contact the surrounding tubular member.
