概述
OurPremier™Packer是一种液压设置的大孔可移动的生产包装器，将永久包装器的性能与可检索的包装器的便利性结合在一起。V0评级的包装工有助于将生产管固定在井中，并防止气体迁移到环。安装V0评级的包装器有助于维持良好的控制，为人们和环境提供保护。
The Premier packer is ideally suited for big-bore completions and multizone, stacked-packer completions. Its retrieving options offer new alternatives to high-intervention-cost applications, and can attain up to API 11D1/ISO 14310 V0-H requirements for high performance. It can be configured for liner-top isolation, monobore completions, stacked single-selective completions, and interventionless deepwater or extended-reach completions.
The Premier packer’s modular design allows it to be threaded directly to the production string or connected with an anchor seal assembly, which provides the option of removing the tubing without retrieving the packer. One-trip setting is accomplished by pressuring up against a plugging device below the packer.
Retrieval on the production string is accomplished by cutting the mandrel with a chemical or mechanical cutting tool. Shift-to-release and shear release options also are available for medium service applications.
