Splet19. feb. 2024 · Swab and surge is a drill pipe operation in which the drill pipe is rapidly cycled up and down in order to generate a surge or vacuum that helps to remove cuttings and other debris from the wellbore. Swabbing and surging helps reduce the time needed for drilling and can improve the efficiency of the overall drilling operation. Removing drill pipe from the well creates swab pressures, which are negative, resulting in a net lowering of pressure in the well. Many problems are caused by the swab and surge pressures. Removing the drill pipe at rates that create large swab pressures can induce well kicks by lowering the wellbore … Prikaži več Computing the swab and surge pressures in drilling is difficult because of the manner in which the fluid flows as the pipe is moved in the well. … Prikaži več If a maximum allowable swab or surge pressure is known, it is possible to determine a maximum pulling or running speed for the pipe. 1.
