Oil well stimulation plays a vital role in production operations. For an oil company and its consumers, it is imperative that as much production be safely extracted from a reservoir. Stimulation treatments, such as hydraulic fracturing and acidizing can create, enhance, or restore a well’s productivity. Usually oil companies will use titanium alloy tubule GR9 (Ti-3Al-2.5V) for Oil Exploitation and Oil Well Stimulation System Application.
The tubule size from OD0.158” ~0.315” (4.0~8.0mm) x WT0.014”~0.02” (0.35 ~ 0.5mm) x Max L0.5” (12000mm) and the GR9 tube can obtain high yield strength through cold-worked and stress-relieved annealing processes. Pressure by hydrostatic tests can be up to 40MPA. Besides titanium GR9 tubes, there is also a commercial pure titanium GR1/GR2, low-alloy GR7/GR16 as well as titanium alloy GR12 for process equipment.
