SS304L Johnson screen casing pipe for oil well

A pipe based screen is exceptionally strong and often is specified for oil wells and deep water wells pipe based screens are used in water wells in many parts of the world and are common in oilfield work because of their strength and durability in non-vertical (deviated) borehole applications. The assembly for this screen is made by perforating a base pipe and then mounting a continuous-slot screen over it via one o three methods: (1) winding trapezod-shaped wire directly onto a pipe (wrap-on pipe); (2) winding wire over longitudinal rods mounted around a pipe's circumference (pipe base); or (3) slipping a separate contnuous-slot well screen jacket over a pipe (screen jacket). Winding wire over longitudinal rods is superior to the wrap-on pipe design because the rods hold the wire away from the pipe surface, blocking fewer of the base-pipe openings.
1. Screens with high open area are more suitable for the construction of high-quality water wells, oil wells and gas wells.
2. Low cost operation Screens with high open area shall favor groundwater infiltration. Abundant water shall reduce the water level’s down, thus to save energy consumption.
3. Reduce the abrasion of the pump
Under the same condition, high open area can make the speed of groundwater’s entering into the screen much slower than any other filtration apparatus, which will avoid sand’s entering into screen because of high pressure, thus reduce the abrasion of the pump.
4. Extend the life span of wells
Comparatively, groundwater’s entering into screen with higher open area is much easier than the entering into lower open area screen. The slow water flow shall extend the life span of wells.
