Compression-Expansion Cementing Segmented External Casing Packer
Hydraulic External Casing Pipe is an important down-hole cementing tool,mainly applied in complicated cementing project of oil and gas well to achieve the purpose of down-hole isolation and bridge plugging to improve and enhance cementing quality.
■ Simple operation avoids the trouble of changing the original technique
■ Extensive application scope is available for oil and gas wells with different conditions
■ The packer element automatically varies according to borehole diameter and down-hole pressure
■ Base pipe has a high strength with the same string drift
■ The packer can be coordinated with relative tools to implement various downhole works
