    Description

    Annulus Casing Packer (ACP) is an inflatable packer assembly designed to be made-up and run in a casing string or liner and inflated in cased or open hole. Its function is to pack off the annulus between the casing or liner being run and the open hole or a previously set string of pipe. Once inflated, the ACP provides an impermeable annular seal in vertical, high angle or horizontal applications.

    Hydraulic expansion type 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

    Features

    1. Continuous one 一 piece mandrel
    2. Identical specifications to casing
    3. H2S and CO2 resistant
    4. Easily replaceable valve components
    5. Easily re-pinned
    6. Available in special clearance
    7. Available in high temperature

    Applications

    Hydraulic inflation Packer is mainly used for oil and gas well cementing operation for all kinds of down hole isolation .It plays an important role to improve the quality of well cementing operation. The tool is not only easy to be operated but also can be used to oil and gas wells with many kinds of down hole conditions. Inflatable element varies with hole diameter and down hole differential pressure automatically. Valve system can make ECP set i the perfect position safely.It’s confirmed that External Casing Packer is an important tool for well completion

    It is an important well completion tool. It’s mainly used in complex oil, gas or water well completion 

    constructions to realize downhole packing or plugging and improve quality of well completion.
