The Y111 series packer can be used in processes such as layered oil testing, oil recovery, water plugging, and acidification. It is a mechanical packer that uses the tail pipe or slip packer as a support point to lower the pipe column for sealing. When lowering the pipe column, the upper joint and the center pipe are compressed downwards to seal the packer and seal the annular space of the oil ring. The unsealing is achieved by lifting the pipe column.

Features/Advantages

Short size and simple structure

Easy to operate, no need to rotate the pipe column

Used in low-pressure environments, with low cost

Normal working temperature and pressure: 120 ℃/35MPa
