Abstract The microstructure and mechanical properties of Ti-Al-V-Mo-Zr titanium alloy drill pipe materials, which have been used in industrial applications, were studied at different annealing temperatures by means testing observation. fracture mechanism strength alloys with parameters discussed. experimental results show that the lamellar structure first dissolves low temperature, then further spheroidized increasing temperature. α equiaxed an equivalent diameter 7.5μm was obtained holding...
Abstract As a consequence of the gradual depletion shallow oil and gas resources, number ultra-deep extra-deep wells is set to increase. The increasingly challenging drilling environment also driving need for new materials rods. Titanium alloy has unique advantages in this regard, including high specific strength, corrosion resistance anti-fatigue properties. Nevertheless, context operating high-temperature environments, thermal stability titanium inadequate, its strength inferior that...
Continuous monitoring of wetland dynamics and regional-scale assessment degradation are important to understand ecosystem processes formulate restoration measures. The lake wetlands in Bashang Plateau play vital roles providing essential resources maintaining biodiversity North China, while they were not fully investigated previous studies. In addition, studies on mostly relied area change every five or ten years. was rarely considered. this study, we developed a new index (WDI) assess based...
Abstract The complex and harsh drilling environment has put forward higher requirements standards for future tools. Compared with other drill pipes, titanium alloy pipe a series of characteristics such as high specific strength, excellent corrosion resistance, fatigue non-magnetic, making it be the first choice material oil gas in unconventional deep well, sea environments. This paper discussed design microstructure properties pipes terms composition, service performance well body processing...
Using station precipitation and reanalysis data, we examined the evolution of large-scale circulations associated with heavy rainfall event that occurred around July 21, 2012 (721 rainfall). This study focuses on a role named “the Okhotsk-Japan (OKJ) circulation pattern” played in causing case. We found 721 under background OKJ persisted for about 10 days. However, pattern was different from normal circulation, this accompanied blocking high between Ural Mountains Baikal Lake. difference...
The application of epoxy-coated tubing used in water injection wells for ~19 to 80 months J oil field was investigated. Testing indicated that one-third the did not meet users’ technology requirement continued use. other showed excellent corrosion resistance. poor surface pretreatment and high-temperature resistance epoxy coating were main reasons failure repaired high working temperatures, respectively. Dissolved oxygen corrosion, carbon dioxide (CO2) under-scale occurred on substrate with damage.
The insulation performance of basin insulator is largely depends on whether there are defects the surface and interior metal electrode. These will cause sudden changes in electric field near it, resulting GIS equipment failure. A comprehensive evaluation method for latent has been presented this paper. screened by partial discharge detection, size location further determined X-ray detection. Based influence various deterioration, a function constructed, harm degree quantified, early warning...
