The main function of screen pipe is sand control. The different geological environment of oil well leads to the different steel grades and types of screen pipe.
1. the screen pipe is made of J55 or N80 oil casing. It has high strength and is not easy to deform.
2. the edge of the slotted edge is good, the edge is smooth, no burr, and the slotting is uniform.
3. Large overflow area, 27/8"screen pipe 300 slots / 1.5m, overflow area 72 per cubic centimeter, 2.4 times larger than the same specifications of tubing overflow area.
4. the advantage of using it in inclined shaft and horizontal well is more obvious.
5. The overall anti-corrosion treatment can form a compact protective layer on the surface of the Wire Wrapped Stainless Steel Screen Pipe, improve the corrosion resistance and wear resistance of the screen pipe, and effectively prolong its downhole working life.
6. is suitable for sand control wells with sand diameter larger than 0.3mm.
In oil drilling and operation, screen tube is an important equipment, often using pre completion or sand control. At present, many screen tubes are used for winding wires. This kind of screen pipe is manufactured by winding a certain section of steel wire on a metal lining pipe evenly distributed on the surrounding screen rod or with a hole and welding it firmly, and leaving a certain gap as the screen pipe. Although this manufacturing method has been used by many factories in China, there are some problems when this kind of screen pipe goes down well, especially when the high pressure passes through the curved section of high deviation well or horizontal well, it will inevitably collide with the well wall or casing, squeeze and friction, and it is easy to appear disordered filament, causing damage to the screen pipe or crack change.
