Devices, Systems and Methods Relating to Down Hole Operations |
摘要 |
A device for improving down hole operations includes a tube that delivers high pressure jets of fluid against the interior surface of a well casing and optionally into perforations of the well casing. The tube also includes a helical array of brushes that scrape and scratch accumulated residue from the interior surface of a well casing and optionally into perforations of the well casing. A method for improving down hole operations includes moving the device into a bend or turn in an existing well casing string and retracting a nozzle or brush to facilitate passage of the device past the bend or turn.
