The Brass Injection Packers are also a kind of packer, which reduces the water blocking construction process of the oil well packer, can conveniently realize the snubbing and no blowout operation, and can withstand high pressure in both directions and has a long service life. The cup packer commonly used in oil fields is self-sealing. The outer diameter of the cup is larger than the inner diameter of the casing, and the seal of the packer is achieved by the interference fit of the cup and the casing. The resistance is large when going down the well, and the cup is easy to wear and scratch, thus losing the sealing performance. With the in-depth understanding of oil layers, it is imperative to tap the potential of thick oil layers. At the same time, higher requirements are put forward for downhole packers.

The above is the specific function and description of the brass injection packer.
