Abstract:
An eductor with a jet ring assembly for generating a low pressure region for detaching and removing residual drilling fluid solids from the internal walls of the eductor is disclosed. The eductor can include: induction ports, liquid induction ports, a mixing chamber, a diffuser, and a jet ring adaptor that can generate the low pressure region. Also disclosed is a method for removing residual drilling fluid solids (wall cake) from internal walls of the eductor. The method can include: stopping the flow of a first pressurized fluid to the eductor, stopping discharge from a diffuser of the eductor, and pressurizing a jet ring assembly using a second pressurized fluid to detach and remove the wall cake from the internal walls of the eductor.
