Downhole milling fraser(ФЗ, ФЗЭ, ФЗи)

Downhole milling fraser, designed for milling cement stone and metal objects in cased wells for the purpose of facing or cleaning along the entire section of the trunk, with centering at the bottom. Depending on the purpose, three types of weapons are manufactured: hard-alloy teeth (ФЗ), hard-alloy plates (ФЗЭ), and impregnated (ФЗи).

Technical parameters

Annular fraser ( ФК, ФКи, ФКУ, ФКУи)

Annular fraser (ФК), designed for milling of attached drill and tubing pipes. Weapons: carbide plates, carbide teeth, designed for working on cement stone, rock, deposits, sludge with separate metal inclusions, impregnated, designed for working with metal objects. For milling metal objects of high hardness, it is possible to manufacture ring cutters with teeth made of "Slavutych" material (hard alloy with natural diamond reinforcement) on special order. There are three types: 1 option-welding connection, 2 option-with a threaded connection, 3 option-with an elongated body (Y).

Technical parameters

Column cone milling fraser ( РАЙБЕР ( ФКК )

Райберы (ФКК), designed for milling damaged sections (crumples, breaks) of casing strings during major well repairs. There are four types of weapons available: 1-carbide plates, 2-carbide plates and teeth, 3-impregnated with carbide chips.

Technical parameters

Magnit holder fraser ( ФЛМ )

Magnit holder frasers designed for milling and extracting small metal objects with ferromagnetic properties located at the bottom of the well.
The magnetic cutter-catcher consists of a housing and a translator. Inside the case there is a magnetic system assembled on the basis of separate permanent magnets, the cutting end is reinforced with a composite alloy.
The principle of operation is based on the use of the cutting end of the body for milling and the action of a permanent magnet to capture and extract small metal objects.

Technical parameters

Pilot fraser ( ФП )

Pilot fraser, designed for milling the upper end of emergency tubing and drill pipes in order to ensure their capture by fishing tools.

Technical parameters

Hydraulic sliding milling fraser(ФР)

Hydraulic sliding milling fraser, designed for cutting out a section of the casing string along the entire diameter in any interval of the borehole for subsequent drilling of the second boreholes. The mill is supplied with a check valve and a set of centralizers. It is a hydraulic device in which, due to the pressure drop, the cutting blades are pushed into the working position, and the full opening of the blades is fixed by the pressure drop on the pressure gauge of the manifold pressure line. The supplied blades can be easily replaced in drilling conditions.

Technical parameters

End milling fraser (ФТ)

End milling fraser (ФТ), designed for milling cement stone and metal objects in cased wells for the purpose of facing or cleaning along the entire section of the trunk.
