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 comprises a material reactive with a component of an earth formation. A method for perforating in a well includes 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 includes a material that can react with a component of an earth formation; detonating the shaped charge to form a perforation tunnel in a formation zone; and allowing the material comprising the liner to react with the component of the earth formation.

1. A shaped charge, comprising: a charge case;an explosive disposed inside the charge case; anda liner for retaining the explosive in the charge case, wherein the liner consisting essentially of a liner material that can chemically react with a component of an earth formation, wherein the liner material is selected from the group consisting of boron, boron alloy, lithium, lithium alloy, silicon, silicon alloy, magnesium alloy, manganese, Fe3O4, Fe2O3, CuO, CoO, Co3O4, NiO, Ni2O3, and PbO2. 2. The shaped charge of claim 1, wherein the liner material is selected from boron, boron alloy, lithium, lithium alloy, silicon, silicon alloy, and magnesium alloy. 3. The shaped charge of claim 1, wherein the component of the earth formation is one selected from calcium carbonate, magnesium carbonate, carbonate, carbon, water, and a hydrocarbon. 4. The shaped charge of claim 3, wherein the liner material is selected from boron, lithium, and manganese. 5. The shaped charge of claim 1, wherein the liner material is selected from Fe3O4, Fe2O3, CuO, CoO, Co3O4, NiO, Ni2O3, and PbO2. 6. A shaped charge, comprising: a charge case;an explosive disposed inside the charge case; anda liner for retaining the explosive in the charge case, wherein the liner consisting essentially of a liner material and a dense component, wherein the liner material can chemically react with a component of an earth formation, wherein the liner material is selected from the group consisting of boron, boron alloy, lithium, lithium alloy, silicon, silicon alloy, magnesium alloy, manganese, Fe3O4, Fe2O3, CuO, CoO, Co3O4, NiO, Ni2O3, and PbO2. 7. The shaped charge of claim 6, wherein the dense component is at least one selected from tungsten, copper, and lead. 8. A method for perforating in a well, comprising: disposing a perforating gun in the well, wherein the perforating gun comprises a shaped charge comprising: a charge case;an explosive disposed inside the charge case; anda liner for retaining the explosive in the charge case, wherein the liner consists essentially of a liner material that can chemically react with a component of an earth formation, wherein the liner material is selected from the group consisting of boron, boron alloy, lithium, lithium alloy, silicon, silicon alloy, magnesium alloy, manganese, Fe3O4, Fe2O3, CuO, CoO, Co3O4, NiO, Ni2O3, and PbO2;detonating the shaped charge to form a perforation tunnel in a formation zone; andallowing the liner material to react with the component of the earth formation. 9. The method of claim 8, wherein the liner material is selected from boron, boron alloy, lithium, lithium alloy, silicon, silicon alloy, and magnesium alloy. 10. The method of claim 8, wherein the component of the earth formation is one selected from carbonate, carbon, water, and a hydrocarbon. 11. The method of claim 8, wherein the component of the earth formation is at least one selected from calcium carbonate and magnesium carbonate. 12. The method of claim 11, wherein the liner material is selected from boron, lithium, and manganese. 13. The method of claim 8, wherein the liner material is selected from Fe3O4, Fe2O3, CuO, CoO, Co3O4, NiO, Ni2O3, and PbO2. 14. A method for perforating in a well, comprising: disposing a perforating gun in the well, wherein the perforating gun comprises a shaped charge comprising: a charge case;an explosive disposed inside the charge case; anda liner for retaining the explosive in the charge case, wherein the liner consists essentially of a liner material and a dense component, wherein the liner material can chemically react with a component of an earth formation, wherein the liner material is selected from the group consisting of boron, boron alloy, lithium, lithium alloy, silicon, silicon alloy, magnesium alloy, manganese, Fe3O4, Fe2O3, CuO, CoO, Co3O4, NiO, Ni2O3, and PbO2;detonating the shaped charge to form a perforation tunnel in a formation zone; andallowing the liner material to react with the component of the earth formation. 15. The method of claim 14, wherein the dense component is at least one selected from tungsten, copper, and lead.
