High quality BPE Slotted liner for oil and water well

BPE slotted liner is the more effective device for sand control, which is generally made from longitudinally welded pipes, seamless steel pipe and stainless steel pipe body.

Oil slotted liner is cut out in the oil casing distributed thousands of slots according to certain rules.

oil slotted liner is slotted by the high power density laser beam focused on the screen using, over under the premise of a laser power density of the laser threshold, the energy of the laser beam and the working gas is formed by cleavage of the auxiliary heat is absorbed by a chemical reaction of the material, thereby causing a sharp temperature rise in the laser beam point of the surface temperature of the sleeve, the working material is partially melted or gasified holes, when the casing and the laser beam has the relative movement, the casing can be cut out of the slot without the contact operation directly. So the cutting progress does not cause any deformation of the base pipe.

The features of BPE slotted liner

1. Slotted edge vertical well, trimming smooth, no glitches, slotted evenly.

2. The opening area and flow area are so big and easy for fluid to flow.

3. high strength, not deformed, its superiority more obvious in deviated and horizontal wells using,

4. the whole embalmed, in the surface of the screen of a dense protective layer improves the corrosion resistance and wear resistance screen, which can effectively extend the life of their underground work.

5. Suitable for sand particle size greater than 0.3mm of sand wells sand.

6. The operation is simple, easy to use, inside diameter large, easy to carry out pipe string configuration.

The patterns of BPE slotted liner

There are three slot patterns designed for different characteristics (as below). Compared to the staggered and straight slot patterns, BPE slop pattern has superiorities over installation torque-loading capacity and substantially improves the liner’s resistance to lateral bucking and collapse pressures.

Slotted Liner Patterns
Staggered Slotted Liner	BPE Slotted Liner	Straight slotted liner
Staggered slots features alternate slot evenly spaced around the circumference with offset.	BPE slots feature multiple slots evenly spaced around circumference in a staggered pattern.	Straight slotted liner features slot columns spaced evenly around the circumference without offset.

The specification of BPE slotted liner

Note: The slot length and slot pattern can be adjusted according to the special requirements of the user.

The slot shape of BPE slotted liner

There are two types of the slot shape: the straight slot and the keystone slot.
