The Y445 packer is primarily used to control the rise of water in oil wells and to implement layered water blocking and oil extraction technology. It can serve as a bridge plug to replace cement plugs in blocking lower high-pressure water layers, or it can be used as a suspended packer for sealing in the upper and lower operations.

PFS high-pressure filling tool is mainly composed of hydraulic part, locking part, sealing part, slip anchoring part, filling part, closing part, hand-lost part, etc. The tool can not only suspend the sealing casing, but also realize the filling operation after opening the filling channel, which can meet the needs of extrusion filling and circulating filling process in the casing.

Reverse filling tool is used for bottom service operations such as fluid replacement, acidizing, wellbore cleaning, and filling in high-angle and horizontal wells.

The screen-type sand screen can be used for both external and internal sand control with filtration and moderate filling. It features multi-layer composite filtration layers, providing high reliability in sand control, with outstanding performance advantages in various aspects. The sand control effect is effective, and it has a long service life.

The Top Filling Sand Control Technology Service uses top-filling tools to complete the entire process of setting the packer, seal testing, releasing, and filling in a single trip of the pipe string. Anton provides top filling technology services and supporting tools for conventional casing completion well types.

This technology is used in loose sandstone oil and gas reservoirs, particularly in water and steam injection development, and in heavy oil reservoirs with severe sand production. When the sand control pipe string cannot be placed at the designed well depth due to continuous sand production from the reservoir, this technology allows for simultaneous flushing and lowering during the descent process, enabling the tools to reach the designed position smoothly. Anton provides reverse filling technology services and supporting tools for conventional casing completion well types.

This technology utilizes a clever combination of packers and filling sliding sleeves to complete the entire process of setting the packer, seal testing, releasing, and multi-layer filling in a single trip of the pipe string. It can provide a one-time multi-layer filling process for 7-inch casing completions.
