The invention discloses a double-cylinder compression packer. The double-cylinder compression packer comprises a center
pipe. The center
pipe is sequentially sleeved with an upper connector, an upper
hydraulic cylinder, an upper
starter, an upper
piston, an upper impelling ring, an upper moving ring, an upper pressing ring, an upper rubber
barrel, a spacer ring, a lower rubber
barrel, a lower pressing ring, a lower moving ring, a lower impelling ring, a lower
piston, a lower
starter, a lower
hydraulic cylinder and a lower connector from top to bottom. Instant
impact force in the setting process of the compression packer is buffered by arranging end portion
copper rings and elastic steel rings at the two ends of the upper rubber
barrel and the two ends of the lower rubber barrel to prevent parts of the compression packer from being damaged by the instant
impact force so that sealing pressure of the upper rubber barrel and the lower rubber barrel on a casing
pipe is more even, and the service life of the compression packer is prolonged. Because a saw-tooth-shaped structure is arranged on the center pipe, the upper rubber barrel and the lower rubber barrel can be effectively prevented from wriggling in the working process. Rubber barrel frameworks are arranged on the upper rubber barrel and the lower rubber barrel in a sulfuration mode and are provided with saw-tooth-shaped structures, so that the upper rubber barrel and the lower rubber barrel are prevented from being damaged in the setting and sealing processes of the compression packer, and the elastic
restoring force of the upper rubber barrel and the elastic
restoring force of the lower rubber barrel are increased in the release process of the compression packer.
