Some knowledge of screen tube

We produce the main function of the oil screen is sand control.

The steel grade and type of the screen are different due.Therefore different geological environment (lithology) of the oil well.

Screen types are divided into: drilled screen, slit screen, wire wound screen, punching screen, meet screen, pre-filled screen, metal wool screen, flexible screen, water control sand control screen.

Screen tube is an important equipment in oil drilling and production, which is often used for early completion or sand control. The most commonly used screen is the wire wound screen.

Individual winding screen

The main description method of wire wound screen tube is as follows:

1. 1.5 ½” spiral screen ,JR electrogalvanized ,2m, /joint,Carbon ，steel S 235 JR electrogalvanized。
2. 2.5½ “Wire wound screen, JR galvanized, 2m long/root, joint carbon steel, S 235.
3. Implementation standard: SY/T 5182-2008
4. The same material should be used for the ribs and winding wires.
5. The cross section shape of the bar and the wire is: V; U; T.

Drawing of wire wound screen

Our method of producing winding wire sieve tube is : winding steel wire of some section and welding firmly on the metal liner uniformly distributed around the sieve rod or the opening, and leaving a certain gap as the sieve hole. 

Our domestic although many domestic manufacturers have adopted this manufacturing method, but the screen in the well has some problems, especially in the crush by high Angle Wells or horizontal Wells of bending section, the inevitable collision with wall or casing, extrusion and friction, prone to floss phenomenon, cause the screen damage or crack deformation, the quality of well completion and sand control effect of reducing or failure, Therefor In order to solve the problem of wire wound screen, the slotted screen tube with one pipe and one seam appeared. My products because of its superior performance and low price, slotted pipe has been highly valued and widely used by major oil fields since its emergence.

In conclusion,we produce slit screen pipe diameter: 60-508mm, seam width range: minimum seam width 0.15mm, rectangular seam, trapezoidal seam,

Processing: mechanical seam cutting, laser cutting
