摘要： A turbine matrix sleeve in accordance with the invention includes an inner cylindrical structure made up of a first material. The inner cylindrical structure may include multiple blades and multiple channels running between the blades along an outside diameter thereof. The inner cylindrical structure further includes threads, such as right-hand or left-hand threads, on an outer surface thereof. An outer layer, made up of a second material different from the first material, is integrally bonded to the threads. This outer layer may be optionally embedded with hardened inserts or buttons, such as PDC inserts, diamond inserts, TSP inserts, or the like. The threaded surface on the inner cylindrical structure significantly improves the bond between the outer layer and the inner cylindrical structure and creates a mechanical lock therebetween.

摘要： A method of opening an orifice in a downhole article includes forming a downhole article having an orifice, the orifice having a selectively removable plug sealingly disposed therein, the selectively removable plug comprising a selectively removable plug body formed of a plug body material and a selectively removable sealant coating formed of a coating material disposed on an outer surface of the plug body. The method also includes disposing the article within a wellbore. The method further includes exposing the selectively removable plug to a first wellbore fluid that is configured to selectively remove the sealant coating and provide a fluid access to the plug body. The method further includes exposing the selectively removable plug body to a second wellbore fluid through the fluid access that is configured to selectively remove the plug body and using the second wellbore fluid to break the sealant coating into a plurality of pieces.
