Application and classification of packers

Packer is a special tool used to pack oil, gas and water layers in downhole casing or open hole. Through external force, it shortens the length and enlarges the diameter of the rubber tube, seals the oil and the annular space, separates the oil (gas, water) layers above and below the packer, so as to realize the layered test of oil and water wells, layered oil recovery, Layered water injection, layered transformation and sealing of water layers.
1. Classification of packers
According to the different working principles of packers, packers are divided into four types: self-sealing, compression, expansion and combined.
Second, the numbering method of the packer
It is arranged in sequence according to packer classification code, fixing method, setting method, unsealing method, rigid body outer diameter, performance code, design unit code, working temperature and pressure.
The design unit code uses the first two Chinese pinyin letters representing the design unit. The design unit starts with the capital letter C for the oil production plant, and the Arabic numerals represent the oil production plant.
The temperature unit is °C, and the pressure unit is MPa. High Pressure Steel Injection Packer is your good choice.
