“…By comparing V150, Ti, S135 and G105, Xianbo Peng [17] found that titanium alloy drill pipe has the highest specific strength, and titanium alloy drill pipe still has significant fatigue life advantages under both single factor and multi-factor coupling. Jackie E. Smith [18] modeled titanium alloy drill pipe to analyze the performance of drill pipe in ultra-deep and deep directional drilling. According to laboratory tests, when the cyclic stress is between 30000psi and 40000psi, the fatigue life of titanium is 10 times greater than that of steel.…”

The complex and harsh drilling environment has put forward higher requirements and standards for future drilling tools. Compared with other drill pipes, titanium alloy drill pipe has a series of characteristics such as high specific strength, excellent corrosion resistance, fatigue resistance, and non-magnetic, making it be the first choice of material for oil and gas drilling in unconventional deep well, deep sea and other harsh environments. This paper discussed the design and microstructure properties of titanium alloy drill pipes in terms of alloy composition, service performance as well as pipe body processing and joint connection. Combined with the development of the application and standards of titanium alloy drill pipe, the prospects of the development and application of titanium alloy drill pipe in unconventional drilling operations such as deep wells and ultra-deep wells were foreseen, in order to provide support for promoting the application and development of titanium alloy drill pipe in the oil fields.

“…In drilling operations this is synonymous of a higher drill pipe distorsion in the wellbore and a buckling risk. A small number of theoretical and experimental studies have been conducted on the risk of buckling for steel, aluminium and titanium drill pipes (Smith et al 2 , Gelfgat et al 1,4 ,Akgun et al 5 ). In the following section we will discuss the drill pipe buckling studies and theory.…”

“…A larg part of these studies concentrated on the buckling phenomenon assuming steel drill pipes. Few studies (proposed by Gelfgat et al 1 & Smith et al 2 ) provided informations about buckling behavior of aluminum and titanium pipes. Today, materials such as aluminum or titanium are considered as viable options for drilling operations.…”

Which Material is Less Resistant to Buckling: Steel, Aluminum or Titanium Drill pipe?

Access to reservoirs in ultra-deep and extended reach drilling projects leads the industry to develop new resistant and higherstrength materials. Drilling equipments manufacturers and drilling contractors have to meet higher requirements of operators to manufacture and operate quality tubulars in these severe environments. However, with the increasing complexity (deep, long, high-pressure/high-temperature, sour service) of drilled wells, steel may become a limiting drill pipe material. A nonsteel alternative material may exist such as aluminum, titanium or composite materials. Buckling of steel, aluminum and titanium tubulars inside wellbore has been the subject of researches and articles in the past. According to some authors, the light Young Modulus of lightweight drill pipes does not affect their buckling response: the relative low stiffness of the pipes would be balanced by reduced contact forces with the wellbore. This paper presents a full study discussing clearly the buckling response of steel and lightweight drill pipes in both experimental bench and real field conditions. This paper shows a full comparative study between steel, aluminum and titanium drillstrings in Extended Reach Drilling (ERD) wells and studies the opportunity to use aluminum and titanium drillstring in ERD wells while the buckling, drilling efficiency and drillstring integrity stay acceptable. Critical buckling loads for each drill pipe material and dimension is reviewed and presented, using our numerical model and in the form of charts which could be used by drilling engineers. Along this comparison, we also focus on drillstring rotation, tool-joints and dimensions effects on buckling loads. Finally, this paper should give a better comprehension of the mechanical behavior of lightweight material for drill pipe, which can improve significantly well planning to drill wells with an increasing depth, length and complexity.

“…Grant Prideco, RTI Energy Systems, and Torch Drilling Services in the United States frst used titanium drilling pipes for industrial applications in 2000. In recent years, many scholars have carried out relevant research on titanium alloy drill pipes; Jackie et al [17] studied the processing method of titanium alloy drill pipes and used simulation technology to model and analyze titanium alloy drill pipe operation in ultradeep wells. Yang et al [18] tested the tensile, torsional, and internal pressure resistance of titanium alloy drill pipe, and the structure showed that the strength of a titanium alloy drill pipe was equivalent to that of a steel drill pipe.…”

Traditional steel drill pipes can no longer meet the requirements of complex wells with ultradeep, ultrahigh pressure, and long horizontal section; hence, titanium alloy drill pipes are an ideal substitute. This paper explores how titanium drill pipes behave in complex wells. The extrusion and tensile test of titanium alloy pipe was first established. Then, based on the experimental data, the downhole mechanical behavior of a titanium alloy drill pipe was studied from the buckling, contact force, and operating friction with an actual complex well. Meanwhile, the mechanism of friction reduction is analyzed and discussed. The research achievements indicate that the strength of a titanium alloy drill pipe is equal to that of a steel pipe and has good plastic deformation capacity. The titanium alloy drill pipe is more prone to buckling during operation, but it has a smaller contact force, which can effectively reduce the operation friction. It was found that the influent of buckling on slide force was much less than of the gravity and stiffness by mechanism analysis. The research achievements can provide specific theoretical and practical references for the revelation of the mechanical behavior and functional performance of titanium alloy drill pipe in the field operation.
