Abstract

An apparatus for performing abrasive jet perforating in a well comprises a generally cylindrically shaped tube with a side, an upper portion, and a lower portion; a plurality of smooth holes drilled into the side of the tube; abrasive jets mounted in at least some of the plurality of smooth holes; protective plates mounted in the side of the tube and surrounding the abrasive jets to hold the abrasive jets in place; wafers recessed into pockets on the protective plates and surrounding the abrasive jets to protect the abrasive jets from damage due to rebound of abrasive-carrying fluid slurry ejected by the abrasive jets; and fasteners securing the protective plates to the side of the tube and positioned away from the rebound of abrasive-carrying fluid slurry ejected by the abrasive jets.
