Usage

Infatable external casing packer is mainly applied to complicated engineering of well cementation,in order to achieving well-packing and bridge blinding.It also can be used to pack well permanently without well cementation.

Advantages

1.Simple operation,no need to change the orignal operating craft.

2.Better adaptability,being applicable to oil,water and well under various different condition.

3.Valve system can effectively protect and exactly control the tools to take setting safely.

4.The expansion coefficient of rubber barrel is large,so it can pack the big borehole.

5.Sealing assembly is consisted of several sealing units.It has bilateral sealing function,and good sealing performance.

6.It has high temperature resistant level,and can bear big differential pressure,with samll residual deformation.

7.It can be used  united with other well cementing tools to achieve well cementing under different  condition,in order to effectively solve the complicated problems of oil well and gas well cementing,eg:high pressure,low pressure,leakage,backwater,collapse and so on.
