What Are The Characteristics Of Oil Screens?

1. The main function of the oil screen is to prevent sand. The geological environment in which the well is located (different lithology) leads to different steel grades and types of screens.

2. Types of oil screen: 1. slotted screen; 2. bored screen; 3. wire-wound screen; 4. bridge screen; 5. composite screen

3. Characteristics of oil screen:

1. The oil screen tube is processed by J55 or N80 oil casing body, which has high strength and is not easy to be deformed.

2. The edge of the slit is perpendicular, the trimming is smooth, no burr, and the slit is even.

3. The flow area is large, 300/8” screen tube 300 slits/1.5m, and the flow area is 72 per cubic centimeter, which is 2.4 times larger than the overflow area of the tubing of the same specification. It is good for liquid flow.

4. The advantages of using it in inclined wells and horizontal wells are more obvious.

5. The whole process of anti-corrosion treatment forms a dense protective layer on each surface of the screen tube, which improves the corrosion resistance and wear resistance of the screen tube, and can effectively prolong the life of the downhole work.

6. It is suitable for sand prevention in sand production with sand particle size greater than 0.3mm.

7. Simple operation, easy to use, large internal diameter, easy to configure the string
