Multi-channel bypass screen

The multi-channel bypass screen is used for long-distance horizontal section gravel packing. The screen can provide multiple interconnected flow paths to transport mortar, and the screen bypass flow path can run through the entire length of the screen. When filling, it encounters a local annular barrier formed in the space of the wellbore, such as stratum collapse, irregular local wellbore, and blockage caused by clay expansion in the mudstone section. The bypass screen can ensure smooth filling and 100% of the open hole section. Gravel packing effect.

Performance characteristics:

1. Optimized bypass channel structure, three delivery pipes and two filling pipes

2. Increase the mortar flow area to improve the reliability of sand control

3. The mortar can bypass the annular barrier during filling to achieve maximum filling efficiency

4. Special design at the screen joints to ensure the connectivity of mortar transportation

5. Convenient access to the well on site and convenient connection

6. The screen structure is reliable and can cope with complex well conditions
