Although aluminium alloy pipe has developed a GB/T20659-2006 aluminium alloy pipe, and in 2007 enacted on May 1, but there have been no a drill pipe in our country enterprise can produce aluminum alloy oil drill pipe. In the drill pipe is used for oil drilling industry have already for a long time, use the experience usually comes from its oil country Russia and neighbouring countries. Aluminium alloy pipe has many advantages, the main is: under the condition of the same strength, it is the weight of the steel pipe 1/2 or so, so in terms of transportation and labor, equipment, power have made a lot of savings, wall thickness increases, its wear resistance, service life is extended greatly, is more than twice higher than the life of the ordinary drill pipe; Aluminium alloy pipe to big, and thus its impact resistance is strong, which improved the working conditions of drill bits in bottom hole, prolong the life span; Corrosion resistance is strong, not easy oxidation, susceptible to erosion, stability is strong. Its disadvantage is that the lower yield strength, especially under high temperature, the yield strength will fell sharply; Wall thickness to be thicker than the steel pipe, causing the deterioration of water horsepower. Tarim oilfield exploration and development in our country, to Russia bought two sets of aluminum alloy pipe, expensive, procurement is very difficult, need to promise not to used in military industry. Not ideal, but the use of low strength is its main defects.
