Method and apparatus for removing debris from a wellbore

摘要

The invention comprises a tool with at least one extending member which causes the fluids moving in the wellbore after perforation to increase in velocity. The velocity is further increased by an auxiliary flowpath which permits the addition of fluid from the surface or from elsewhere in the wellbore or formation to be pumped to mix with the other fluids being produced after perforation. The auxiliary fluid further increases velocity, thus improving the ability of the mixture of formation and auxiliary fluid to entrain debris and remove it from the wellbore.
