When it comes to sand control in oil and gas wells, slotted casing is the ideal solution. It offers effective filtration to prevent sand from entering the wellbore while allowing oil and gas to flow freely.

When it comes to sand control in oil and gas wells, slotted casing is the ideal solution. It offers effective filtration to prevent sand from entering the wellbore while allowing oil and gas to flow freely. Slotted casing is primarily made from high-strength J55 or N80 oil casing, which ensures its durability and prevents deformation.

With good perpendicularity of cutting edge and smooth surface, slotted casing has no burrs or uneven cutting edges. The cutting edge is even, ensuring maximum flow through the screen. The large flow area in 2 7/8" screen pipe with 300 slits/1.5m is particularly advantageous in inclined and horizontal wells. It boasts a flow area of 72 per cubic centimeter, which is 2.4 times larger than the tubing of the same specification, making it highly conducive to liquid flow.

Slotted casing undergoes overall anti-corrosion treatment, which forms a dense protective layer on each surface of the screen pipe. The protective layer improves its corrosion resistance and wear resistance, effectively extending its downhole service life. Suitable for sand control of sand production wells with sand particle size greater than 0.3mm.

Slotted casing is easy to configure and operate.Its simple operation and ease of use make it a desirable choice for the oil and gas industry.

In conclusion, slotted casing is the ideal solution for sand control in oil wells, providing effective filtration, high durability, and ease of operation.
