Snubbing technology is an operation method about lifting and running the tubing string under pressure for the oil and gas well to ensure the safety of the oil and gas well operation without the use of control fluid. When tripping the strings under pressure at wellhead, the BOP stack, bridge plug or blanking plugs must be used at surface to control the pressure in oil/gas well. The safe BOP stack is a basic guarantee for oil/gas well control. The snubbing technique is mainly used in the oil/gas wells where under–balanced pressure should be maintained all the time.
Snubbing technology is an operation method about lifting and running the tubing string under pressure for the oil and gas well to ensure the safety of the oil and gas well operation without the use of control fluid.
In the process of lifting and running tubing string with pressure at wellhead, tools such as surface BOPs, bridge plug or plug are needed to jointly control the pressure of oil and gas well.
Safety BOPs is the basic guarantee of oil and gas well control.
Snubbing technology is mainly used in oil and gas wells that need to be operated in an under-balanced state all the time.
