Abstract

The invention discloses a composite rubber sleeve packer comprising a core tube, an axial compression device and a rubber sleeve component, wherein the axial compression device and the rubber sleeve component are sleeved on the core tube, and the rubber sleeve component is composed of a pressure expanding rubber sleeve and liquid expanding rubber sleeves. The composite rubber sleeve packer has the advantages of rapid setting and long setting time.

Description

technical field [0001] The invention relates to the technical field of downhole tools used to seal off annulus during well cementing and completion, stimulation operations or oil recovery construction in the petroleum industry, in particular to a composite rubber cartridge packer. Background technique [0002] The packer in the prior art achieves setting by extruding a packing rubber cylinder in a hydraulic or mechanical compression manner. This type of packer has been widely used in the fields of petroleum solid completion, oil recovery, and production stimulation. One of the advantages of the packer is that the setting speed is fast, and one of the disadvantages is that sealing failure is prone to occur during long-term downhole operation. [0003] In view of this, the inventor actively researched and innovated, and finally invented a composite rubber cartridge packer with a novel structure to solve the problems in the prior art and make it more practical.
