The 664WCY series pipeline crossing packer integrates the pipeline crossing channel into the retrievable packer, and controls the hydraulic sleeve, measuring instruments or injection of chemicals in the lower wellbore through the safety channel of the packer pipeline. The packer can be unsealed by lifting the oil pipe.

This series of packers is directly connected to the production casing through threads, and the packer is lowered to the required depth, and a predetermined pressure is applied to shear the pin to set the packer. The bidirectional anchoring slip design can resist the forces from both the upper and lower directions, effectively preventing the packer from moving up.

Features:

• Simple and robust modular design
• The slip-rubber sleeve - slip structure is separated from the high-pressure environment, reducing three-dimensional stress
• The crossing pipeline and the packer body are fully metal sealed
• Adding an auxiliary piston option, the setting pressure is lower, and more operational flexibility in underbalanced completion
• The setting piston is located below the rubber cartridge, which is beneficial to the final well protection
