Sand control screen
Sand control screen
Sand control screen / high density blister screen by the base pipe, stainless steel punching filter sleeve and support file ring composition.
Sandproof screen tube with excellent overall strength and resistance to deformation: punching filter inside the support by the base pipe, the overall strength of the drilling through the standard casing / tubing only decreased by 2 to 3%, with sufficient overall strength Resist the deformation of the formation. Even if the local deformation, the pressure of the gap does not increase, sand control and high reliability.
Features
1, precision and control of the gap: punching width in the range of 0.1 ~ 1.00mm precise control, width accuracy ± 0.05mm, can better match the composition of the sand with different sizes to meet the needs of underground sand control.
2, excellent corrosion resistance: stainless steel punching filter sets of acid, alkali, salt corrosion, to adapt to H2S, CO2, high Cl wells of the special requirements, long-term use of the gap will not be gradually widened due to corrosion.
3, excellent overall strength and resistance to deformation: punching the inside of the filter through the base pipe support, the overall strength of the drilling through the standard casing / tubing only decreased by 2 to 3%, with sufficient overall strength against the formation Of the extrusion deformation. Even if the local deformation, the pressure of the gap does not increase, sand control and high reliability.
4, high-density gap, low flow resistance: punching screen hole opening rate is 2 to 3 times the ordinary slotted screen, low flow resistance, is conducive to improving oil and gas production.
5, good craftsmanship, to achieve a high efficiency, low cost, large-scale production.
