What kind of packer industry does the Brass Injection Packers belong to? what is the purpose
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.
- Classification of packers
According to the different working principles of packers, packers are divided into four types: self-sealing, compression, expansion and combined.
- Numbering method of 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 adopts 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.
(1) Y341—114—X—C4—90/15 type packer, which means that the packer is compression type, fixed suspension, hydraulic setting, lifting and releasing pipe string unsealing, the maximum outer diameter of the steel body is 114mm, Washable well packer for water injection well. The design unit is the Fourth Oil Production Plant. The working temperature is 90℃ and the working pressure is 15MPa.
(2) Y341—114—D—CY—90/15 type packer, which means that the packer is compression type, fixed suspension, hydraulic setting, lifting and releasing pipe string unsealing, the maximum outer diameter of the steel body is 114mm, The water plugging packer for oil wells is designed by the Oil Production Technology Research Institute, with a working temperature of 90℃ and a working pressure of 15MPa.
