Aluminum Alloy Drill Pipe

Aluminum drill pipe has the advantage of low density, high strength, corrosion and fatigue resistance, good processing performance and excellent low temperature toughness. It is a promising technique to solve the drilling problems arising from complex working conditions of the deep and super deep well, horizontal well, extended reach well, sour well and offshore well etc. As it can improve the efficiency and safety of drilling, the technique of aluminum drill pipe is significant important. The feature and process of aluminum drill pipe in recent years are reviewed. Some proposals for the application of aluminum drill pipe in China oil and gas industry are also provided.
