Experimental Study on the Behavior of Gas–Water Two-Phase Fluid Flow Through Rock Fractures Under Different Confining Pressures and Shear Displacements

Water (2025)

Yang Wang Kangsheng Xue Cheng Li Xiaobo Liu Boyang Li

Understanding the flow behaviors of two-phase fluids in rock mass fractures holds significant importance for the exploitation of oil and gas resources. This paper takes rock fractures with different surface roughness characteristics as its research object and conducts experiments on the gas–water seepage laws of fractures under various confining pressures and shear displacements. The results indicate that the higher the fracture surface roughness, the larger the equivalent fracture width and the higher the single-phase permeability of gas/water in the fractures. During gas–water two-phase flow, when the water phase split flow rate is high, the influence of the confining pressure and fracture surface morphology on the water phase is significantly higher than that on the gas phase. The relative permeability at the isosmotic point of the fractures increases with the increase in confining pressure and decreases with the increase in roughness. After the dislocation of shale fractures, the interphase resistance within the fractures reduces. The relative permeability of the water phase increases more significantly compared to that of the gas phase. The water phase split flow rate at the isosmotic point does not change significantly, and the relative permeability at the isosmotic point increases. This research is helpful for guiding the protection based on the conductivity capacity of the rock mass fracture network.

Effect of Adding Rare Earth Elements Er and Gd on the Corrosion Residual Strength of Magnesium Alloy

Open Physics (2019)

Miao Yang Xiaobo Liu Zhiyi Zhang Yulai Song Lei Bai

Abstract The effects of the single and compound addition of rare earth Gd and Er on corrosion resistance and residual strength of as-cast AM50 magnesium alloy were studied using XRD, SEM, EDS, the weightlessness test, electrochemistry method, and tensile test. The results of XRD and SEM showed that Al 3 Er, Al 2 Gd 3 , and Al–Mn–Gd(Er) phases appeared in the alloy structure after the addition of rare earth Er and Gd. The results from the weightlessness test and Tafel curves show that the corrosion resistance of the modified composite rare earth was improved. Stress concentration caused by a corrosion pit is the direct cause of the tensile samples after corrosion. The corrosion residual strength of modified composite rare earth specimens is better than that of modified single rare earth samples. Fracture analysis indicates that the addition of rare earth elements did not change the fracture mechanism of the alloy, and the fracture was still the cleavage fracture.

Recyclable Adsorption Removal and Fluorescent Monitoring of Hexavalent Chromium by Electrospun Nanofibers Membrane Derived from Tb <sup>3 </sup> Coordinating Polyarylene Ether Amidoxime

Qimeng Ran Danlei Zhao Yao Ji Zilin Fan Guo Lin

Emerging technologies or advanced materials which can simultaneously adsorb and detect highly toxic Cr(VI) are urgently in demand for environmental remediation. Herein, we have designed and synthesized a functional polyarylene ether with aromatic main chain and pendent carboxyl groups along with amidoxime group that can be coordinated with different metal ions. Thanks to its versatile activation of the lanthanide ions' inherent fluorescence and good processability, the fluorescent nanofiber membranes with competitive Cr(VI) adsorption and detection performance have been fabricated via one-step electrospinning of mixed solution containing synthesized polymer and terbium salt. More specifically, the optimized nanofiber membrane exhibits a maximal Cr(VI) adsorption of 278.2 mg/g and sensitive detection for hexavalent chromium down to 11.76 nM. More importantly, the prepared fluorescent nanofiber membranes can be easily re-generated and re-used for both Cr(VI) adsorption and detection for five times. Given the unique advantages of easy fabrication, competitive dual functionalities as well as good reusability of electrospun fluorescent nanofiber membranes, the present work basically opens up new insight in the design of multifunctional recyclable material for the remediation of heavy metal pollution.

Determination of Ammoniacal Nitrogen and Nitric Nitrogen on Soilless Culture

Journal of Shangrao Normal College (2006)

Xiaobo Liu

KCl aqueous solution(2mol·l~(-1)) was used to extract the ammoniacal nitrogent and nitric nitrogen from media of soilless culture.The weight ratio of media to extractant was 1∶5.After 30 minutes vibration,ammoniacal nitrogen was determined at 645nm by indophenol blue colorimetry,the regression equation:A=0.7358C+0.0044,r=0.9994(n=7),the rate of recovery:103.6%.nitric nitrogen was did at 205nm by UV-spectrophometry,the regression equation:A=0.5654C+0.0127,r=0.9994(n=9),the rate of recovery:102.4%.

Research of Comprehensive Utilization of Coal Gangue

DEStech Transactions on Engineering and Technology Research (2018)

Jia Ming Han Xiaobo Liu Weiwei Yang Jiping Liu

Oil and coal are abundant in China and it is a superiority for the development. Coal gangue come from the course of coal exploitation, and processing, which is one of the solid wastes of industry biggest in emission of our country. How to solve this environment pollution and effectively utilize the coal gangue is a main subject and difficult problem faced at present. In this paper, we performed a comprehensive analysis of the development about comprehensive utilization of coal gangue, and provided a basis for the research of coal gangue and environmental protection.
