Precision Punched Sand Control Screen, Sand Control PPS Screen
PPS screen mainly consists of perforated base pipe, stainless steel
filtration jacket with punched slots and rings. It can be sued for
casing completion and liner completion of vertical wells, inclined
wells and horizontal wells etc. and it can be used for various oil
wells, gas wells and water wells. It can be used as sand control
colonnade individually and it can be used in gravel packing.
Features:
1. Accurately controlled width: The width of the precision punched
slot screen is accurately controlled within 0.20mm~1.0mm and the
degree of accuracy is ±0.05mm, which can better match the sand
sizes of different formations and satisfy the requirements of down
hole sand control.
2. Excellent anti-corrosion ability: Precision Punched Screen
jacket is made of high quality stainless steel, with better
resistance of acid, alkali and salt corrosion, can meet the special
requirements of the wells containing H2S, CO2, and high CL. The
slot will not get wider after long time service.
3. Excellent body strength and anti-deformation ability: The
filtration jacket is supported by the base pipe, and the strength
of the perforated base pipe is only 2~3% reduced compared with the
API casing or tubing, which ensures the excellent body strength and
anti-deformation ability of the precision punched screen. Even if
there is partial deformation, the slot width will not get wider
because of its high reliability.
4. High density slot, low flow resistance: The flow resistance is
lower because the hole area of the Precision Punched screen is 2~3
times of the normal slotted screen, thus increasing the oil and gas
output.
