Characters:
1. Designed for thermal production oil well.
2.Working temperature:370°C
3. Good performance of seal and compensation, can expand or shrink according to the temperature changing.
4. Easy operation and maintain
The packer comprises a compensation pipe, where in one end of the compensation pipe is mutually connected with an over, and a lower joint is connected at the other end of the compensation pipe; the packer is arranged on the compensation pipe. After installation, you can seal the space between the tubing string and the casing, so that high-temperature hot steam directly into the formation; prevent gas went on more parts, thereby protecting the well casing, improve the efficiency of steam injection.
