Petroleum slotted screen pipes are divided into two categories: petroleum slotted pipes and water harvesting slotted pipes, which use various steel grade pipes. Comply with API Spec 5CT regulations, adapt to various requirements. Slotted screens are used to cut multiple specifications of longitudinal or spiral straight gaps on the oil casing or in a variety of ways. It is made after cutting with a cutting sheet and beam. Its slit width is (0.2-0.4) mm (according to customer requirements), and the slit length can be greater than 20mm (according to user requirements). The cross section of the slit is rectangular and trapezoidal. The layout of the slit can be processed according to user requirements. This product has good sand control performance, no blockage, and improves oil production quality. It is mostly used in horizontal wells, side drilling and branch wells. 

Performance parameters of oil screen

Petroleum screens are used to cut multiple specifications of longitudinal or spiral straight and staggered gaps on the petroleum casing or in a variety of ways. It is made after cutting with a cutting sheet and beam, and its slit width (0.2-0.5mm). The cross section of the slit is rectangular, trapezoidal (trapezoid angle is 3-8 degrees) and special shape (round hole), etc., and the permeability is 0.5%-10%. The layout of the slits can be processed according to user requirements. The slotted edge of the slotted screen has good verticality, smooth and thorny cutting edges, and uniform slotting.

The main parameters of oil screen pipes include material, wall thickness, caliber, number of slits, slit specifications and screen length. The main machinery and equipment for general slitting screens is slitting machines, and there are about ten slitting machines for general oil screen manufacturers. The material of the oil screen is mainly oil casing, which is basically used as the raw material for making slotted screens.

Oil slotted screen

Types of oil screens: slotted screens, drilled screens, wire-wound screens, bridge screens, composite screens.

Petroleum slotted screen is a kind of production process and product in petroleum screen. The main parameters of slotted screen are material, wall thickness, caliber, number of slotted slots, slot size and length of screen.

The slotted screen will form a very dense protective layer on the surface of the screen when the overall anti-corrosion treatment is carried out. With the protection of this protective layer, the corrosion resistance of the screen is greatly improved. It can effectively extend the service life of the petroleum slotted screen pipe in the underground operation of petroleum drilling, thereby reducing cost consumption.

In oil drilling and production operations, screens are an important piece of equipment, and early completion or oil production and sand control are often used. At present, the most commonly used screen is the petroleum slotted screen. The manufacturing method of this kind of screen is as follows: a certain cross-section steel wire is wound on a metal liner evenly distributed on the surrounding screen rods or perforated and welded firmly, and the gap left as the screen hole.
