Filtration system and method for a packer

摘要

Filtration systems, methods and/or apparatuses for use on a packer system are provided. Filtration assemblies and/or filters may prevent mud, gravel, and/or other solids from clogging and/or entering drains on a packer. The filters and/or filtration assemblies may have multiple dynamic components to prevent debris from entering the packer system. Rotary filters, cylindrical filters, and/or belt filters may be used to clear fluid obstructions from sampling drains. Helices and/or turbines may harness power of fluid flowing through the drains and/or flowlines to operate moving dynamic components of systems and/or apparatuses. The filters and/or filtration assemblies may be interchangeable such that various filters may be used on a single packer system.
