摘要:
A shaped charge includes: a charge case; an explosive disposed inside the charge case; and a liner for retaining the explosive in the charge case, wherein the liner is fabricated from a material soluble with a selected dissolving fluid (e.g., an acid, an acid matrix, an injection fluid, a completion fluid, and/or a wellbore fluid). A method for perforating in a well includes the steps of: disposing a perforating gun in the well, wherein the perforating gun comprises a shaped charge having a charge case, an explosive disposed inside the charge case, and a liner for retaining the explosive in the charge case, wherein the liner is fabricated from a material soluble with a selected dissolving fluid; detonating the shaped charge to form a perforation tunnel in a formation zone; and exposing the material comprising the liner to the selected dissolving fluid.
