Abstract

The invention discloses a basalt fiber and ceramic particle mixed aluminum alloy drill rod material and a preparation method thereof. The aluminum alloy drill rod material is formed by cold pressing, sintering, extrusion and heat treatment of an aluminum alloy substrate, basalt fibers and nano ceramic particles. The mechanical property and temperature resistance of the adopted basalt fibers are excellent, the basalt fibers serve as a high-property environment-friendly inorganic material, the basalt fibers are obtained from igneous rock and applied to developing drill rod materials for underground strata drilling, and the material is prepared from the rock and applied to the rock and is environmentally friendly; and the material is highly targeted, the hardness, abrasion resistance and strength of the aluminum alloy drill rod material are mainly improved, the service life of an aluminum alloy drill rod during deep well (hole) drilling is prolonged, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of micro-nano functional materials and drilling tool materials, and in particular relates to a basalt fiber and ceramic particle mixed aluminum alloy drilling rod material and a preparation method thereof. Background technique [0002] With the rapid development of oil, natural gas and geological exploration industry, the requirements for operating technology and equipment are getting higher and higher. Deep well and ultra-deep well operations have more stringent requirements for light weight, temperature resistance and wear resistance of drill pipes. Aluminum alloy drill pipes As a high-tech exploration drill pipe, it has the advantages of high specific strength, light weight, small elastic modulus, and good corrosion resistance. It is used in deep wells, ultra-deep wells and high H content 2 S, CO 2 Wells have broad application prospects. For drilling rigs with the same hook load capacity, the use of alu...
