API Casing Packers

Main Technical Features

● Casing Packer (casing external packer) uses hydraulic expansion type structure, mainly be used

in the complex wells'(oil, gas,water) completion project, to achieve down hole packer and

bridging and in favor of improvement of the quality of completion. The practice proved that this

tool have characters of easy operation, wide adaptability, it has a very important position in the

completion project.

● Hydraulic expansion packer mainly consists of valve system joint assembly、rubber barrel、

central tube、casing sub. The valve system is divided into axial valve system and radial valve

system. Radial valve system is composed of a set of three valves
