Characteristics
1,Simple construction operation do not change the original construction process
2,Good adaption could be easy used for a different conditions of oil gas and water wells
3,The valves system can effectively and accurately control tools to protect safety seats seal.
4,Greater expansion coefficient of rubber tube could seal larger diameter borehole packer
5,The seals assembly using multiple sets with two-way sealing function and good sealing effect
6,High temperature resistance ,good pressure undertake ,less residual deformation
7,Can be combined with other cementing tools used to achieve different situations of cementing , an effective solution to high pressure, low pressure leaks back to the water, collapse of complex oil and gas well cementing problems
EXPANDABLE CASING PACKER
