The principle and purpose of High Pressure Steel Injection Packer

High Pressure Steel Injection Packer is your good choice.Refers to downhole tools that have elastic sealing elements to isolate the annular space between various sizes of tubing strings and the wellbore and between the tubing strings, and isolate the pay zone, to control the production (injection) of fluid and protect the casing. In oil production engineering, the packer is used for stratification. The packer is designed with an oil production channel. During setting, the piston sleeve moves up and the oil production channel is opened; after setting, the upper pressure acts on the balance piston, pushing the rubber cylinder upwards, The unsealing pin is protected from shearing force; when unsealing, the unsealing pin is cut by the friction force between the rubber cylinder and the casing, the piston sleeve goes down, and the oil production channel is closed. Advantages: 　　 reduces the water blocking construction process of the oil well packer, can easily 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. With the in-depth understanding of oil layers, it is imperative to tap the potential of thick oil layers, and at the same time, higher requirements are put forward for downhole packers.High Pressure Steel Injection Packer is your good choice.
