Well slotted wire (anti-sand) filter is designed to prevent the removal of sand and other particles during the operation of wells of oil and gas fields, wells with unstable reservoirs of underground gas storages, as well as water intake wells.
Downhole filters are used for separation of produced fluid from mechanical impurities in downhole conditions.
The design consists of a perforated base, a filtering frame and a sludge settling tank.
Conditional total length of the filter, m (3,4,5,6,7,8,9,10,11,12).
Filtration fineness, mm (01 -0,1mm, 02 -0,2mm)
Shaft diameter, mm (20,22)
Evolute inter-section shaft connection
(in case of a straight splined connection, the letter "E" is not used).
