Unlocking and Blowout Preventing Bypass Sub
Thus it is convenient for logging team to deal with accidents.
Unlocking and Blowout Preventing Bypass Sub
Be used in complex wells. When drills are stuck, we can increase cable's tension to separate cable and bypass sub. Then we can pull out the cable from the drill water hole. After that, Blowout Preventing structure blocks the cable hole. Thus it is convenient for logging team to deal with accidents.
Main Technical Indicator:A.Weakness screw tensile strength: 1500 pounds each, maximum six. B.Seal pressure after the cable is pulled out: ≥20MPa
