We provide an oil well thermal recovery packer with simple structure, good sealing effect, safety and reliability, and high steam injection effect.The packer isolates the annulus from the production conduit for high-temperature steam injection, cyclic steam stimulation, and geothermal production wells.
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.
