The invention provides a processing method of a soluble aluminum alloy. The processing method of the soluble aluminum alloy comprises the following steps: a wrapping step of wrapping a soluble aluminum alloy blank with a thin cover to obtain a wrapped blank, the soluble aluminum alloy blank is any one of soluble aluminum alloy with initial tensile yield strength, soluble aluminum alloy with initial tensile ultimate strength or soluble aluminum alloy with initial tensile elongation; and an extrusion step of extruding the wrapping blank through an equal channel angular extrusion die, so that an extrusion machining blank is obtained, wherein the extrusion angle of the equal channel angular extrusion die ranges from 90 degrees to 135 degrees, the temperature in the extrusion step is 150-250 DEG C, the extrusion rate in the extrusion step is 0.003 to 0.01 in / s, and the back pressure in the extrusion step is 200 psi to 10000 psi. The problem that in the prior art, soluble aluminum alloy is high in machining difficulty is solved.
Description
technical field [0001] The invention relates to the technical field of downhole tool manufacturing for oil and gas production, in particular to a processing method for a soluble aluminum alloy. Background technique [0002] Oil and gas production operations usually consist of a wellbore that penetrates the formation and downhole tools such as bridge plugs and sliding sleeves that are distributed along the wellbore. The bridge plug can realize the opening and closing of part of the wellbore, so as to realize the isolation of the corresponding formation section. By opening and closing the sliding sleeve, fluid communication between the wellbore and the formation can be achieved. Downhole tools are used in a variety of operations to prepare and achieve the recovery of hydrocarbons from formations to isolate and open specific formation intervals. When the interval is completed, it may be necessary to remove parts of the downhole tool or even the entire downhole tool. For exam...
