DRH packer is a hydraulic setting completion packer that can be used alone or in combination with multiple packers, especially suitable for high angle wells or horizontal wells where mechanical and cable setting packers are not suitable for drilling. As a means of cross plugging or layered oil production, two or more packers can be used for one-time sealing or sequentially sealing according to design requirements. This packer has the characteristics of safe and convenient setting and unsealing operations, high construction success rate, good sealing effect after setting, and long sealing time, and is suitable for wells containing hydrogen sulfide. The upper part of the packer is designed with a hydraulic anchor structure that can withstand positive and negative pressure differentials; The sealing force and unsealing force can be adjusted as needed, ensuring safe operation and easy lifting.

Features/Advantages

Can be sealed in any level of casing

Suitable for use in high angle and horizontal wells

The sealing method is hydraulic sealing, which does not require rotating the pipe column and can be lifted up to release the seal, making it easy to operate

Good sealing performance, using a three section rubber cylinder sealing system with two different hardness levels

● Can withstand a large pressure difference, capable of withstanding a bidirectional pressure difference of 70MPa (10000psi)

The unique ratchet locking ring device will lock and maintain the sealing force, ensuring long-lasting and effective sealing

Conventional rubber cylinders and seals are recommended to be suitable for temperatures below 148 ℃ (300 ° F), and can be customized for higher temperatures
