fracport是什么东西啊？

The Drillable Closeable (DC) FracPORT™ sleeve is a ball-actuated, hydraulically-activated flow port. It is run between two RockSEAL® II packers to allow specific zones of the wellbore to be isolated and selectively fractured. There are a variety of ball seat sizes, allowing multiple DC FracPORT sleeves to be run in sequence. The DC FracPORT sleeve can be drilled out to remove the ball seat and can be closed or re-opened with or without the ball seat in place for future operations.

Applications
•Open and cased hole
•Horizontal and vertical wells
•HPHT and sour service
•Selective fracturing
•Selective producing
•Future operations such as: ◦Water and gas shut-off
◦Flow control
◦Re-fracturing
  

Features and Benefits
•Ball-actuated, hydraulically-activated
•Can be run in multiples to fracture several independent zones
•Lower zones are isolated due to increasing ball sizes
•Can be closed or re-opened with or without the ball seat in place
•Adjustable activation shear
•Sleeve is locked in place upon opening
•Provides a flow area greater than the liner
•Ball seat can be quickly milled out
•Field-proven resistance to abrasion and erosion
•Corrosion resistant design
