Double Sealing Packer

1. Application

Double sealing packer is a kind of hydraulic compressive packer,which is sealed by pipe pressure and released by pulling the pipe. According to site requirement which is needed to seal interlayer and extract lower layer, some technical improvements have been done. It can succeed by adjusting part dimension according to different layer’s situation.

Double sealing is mainly used for oil extraction, mechanical plugging and other constructions.

2. Structure & Work Principle

Double sealing packer is composed of gas channel, sealing assembly and setting blocking mechanism.

When sealing, fluid pushes the cylinder go up, drives lock tube and barrel seat up to compress the barrel to make it radically deformed. At the same time, slip ring enters sawtooth and lock the barrel to make the casing annulus sealed by packer.

3. Characteristics

1) There’re air inlets in lock tube, so the bottom air can ascend from the annulus to interlayer and gain the aim of extraction.

2) It can be designed and adjusting by interlayer thickness to construction. The Max interlayer is 6m.
