Oil screen tube
The main function of the oil screen is to control the sand. The different geologic environment (different lithology) in the well leads to the different grades and types of screens used.
Oil screen overview
The type of oil screen
1. Slotted screen tube
2. Drilling screen
Wire around the screen
4. Bridge screen
5. Compound screen
The characteristics of oil screen
1. Oil screen with J55 or N80 oil casing body processing, high strength, not easy to deformation
2 kerf edge perpendicularity is good, trimming smooth, burr-free, kerf uniform.
3. Large flow area, 27/8 "screen 300 kerfs / 1.5m, flow area of 72 per cubic centimeter, than the specifications of the tubing flow area 2.4 times greater. Will help liquid flow.
4. The advantages of using inclined shafts and horizontal wells are more obvious.
5. The overall anti-corrosion treatment, the surface of the screen to form a dense protective layer to improve the corrosion resistance of the screen and wear resistance, which can effectively extend the life of their work underground.
6 for sanding sand diameter greater than 0.3mm sand control sand.
7. Simple operation, easy to use, large diameter, easy to configure the tube string

Sewing table: any.
Application Status of Laser Cutting Oil Screen:
In oil drilling operations, sieve pipe is an important equipment, often using pre-completion or oil sand control. Currently, the use of more screen is around the wire screen. The sieve is manufactured by winding a wire of a certain cross-section on a metal liner uniformly distributed on a sieve rod or an open hole, and welding the wire with a certain gap as a sieve hole. Although this method of manufacture has been used by many manufacturers in China, there are some problems with this type of screen pipe when it goes down, especially when it is forced to bend through a bend or a horizontal well, it inevitably needs to be connected with a well wall or a sleeve Tube collision, extrusion and friction, prone to chaos phenomenon, resulting in damage to the screen or gap deformation, resulting in completion of the quality and the effect of sand control to reduce or failure, in view of the drawbacks of silk screens, pipe, seam cutting Screen pipe appeared. Due to its superior performance and low cost, kerf pipes are highly regarded and widely adopted by major oil fields. It can be seen that the emergence of kerf pipes provides the material conditions for the development of horizontal and lateral drilling wells and the oil recovery of the high sand reservoir.
