摘要： A method for operating in a borehole penetrating a formation is disclosed. The method includes disposing in the borehole an assembly comprising a load-bearing and oil-disintegrable tool comprising a polymeric composite; performing a downhole operation; and disintegrating the load-bearing and oil-disintegrable tool with a hydrocarbon fluid. The polymeric composite comprises an oil-disintegrable polymer which is one or more of the following: a polydicyclopentadiene, polypropylene, polyurethane, polycarbonate, polysulfone, or a high density polyethylene, the polyurethane being a polyhedral oligomeric silsesquioxane-modified polyurethane, a lauryl methacrylate graft polyurethane copolymer, a divinylbenzene crosslinked polyurethane, or a combination comprising at least one of the foregoing.

摘要： A novel material used for a bearing ring and a production process thereof is directed to a bimetallic composite pipe and a production process thereof. The aim of the disclosure is to provide a novel material used for a bearing ring and a production process thereof, in which high hardness, high wear resistance and high toughness, high impact toughness are interacted. The novel material used for a bearing ring according to the invention is composed of an annual clad layer and a base layer. The clad layer and the base layer is metallurgy bonded together in radial direction of a ring. The clad layer is made of bearing steel material, and the base layer is made of the material selected from bearing steel, straight carbon steel, high strength low/medium alloy steel or stainless steel.
