Study on mechanical properties of titanium alloy drill pipe and application technology

With the increasing intensity of oil and gas field exploration development, wells are also drilling into deeper more complex formations. Conventional steel tools can no longer meet requirements ultra-deep, high-temperature high-pressure wells. The paper first analyzes advantages titanium alloy drill pipe based on basic performance pipe. experimental results show that properties pipes operating standards petroleum industry. Then buckling is compared, calculation slightly lower than tools. Secondly, maximum allowable buildup rate tool studied. research shows under same condition outer diameter, be used for a smaller curvature radius greater rate. This advantage makes it suitable short ultra-short Finally, taking shale horizontal well as an example, with goal reducing string friction ensuring stability, comparative study application carried out. has wider in field, operations various working conditions.
