1. Application
RTTS is a mechanical slip packer, mainly applied to formation testing in high temperature and pressure, oil extraction, water injection, water exploration, plugging, squeezing acidification, fracturing and so on.


2. Structure and Principle
RTTS packer consists of hydraulic anchor, rubber barrel, slip holder, slip, slip bracket, reversing friction block, outer central pipe, inner central pipe, upper joint and so on.
RTTS mechanical slip packer is supported by unidirectional slip. It's set by pulling, turning and lowering. Released by pulling the column.


3. Characteristics
1) The rubber barrel is above the slip in order to avoid covering by sand.
2) Simple structure and easy to operate.
