| 2 | Incipient mechanical fault detection based on multifractal and MTS methods显示文摘An incipient mechanical fault detection method, combining multifractal theory and Mahalanobis-Taguchi system (MTS), which is based on statistical technology, is proposed in this paper. Multifractal features of vibration signals obtained from machine state monitoring are extracted by multifractal spectrum analysis and generalized fractal dimensions. Considering the situation of mass samples of normal mechanical running state and few fault states, the feature parameters corresponding to different mechanical running states are further optimized by a statistical method, based on which incipient faults are subsequently identifi ed and diagnosed accurately. Experimental results proved that the method combining multifractal theory and MTS can be used for incipient fault state recognition effectively during the mechanical running process, and the accuracy of fault state identifi cation is improved. | Hu Jinqiu Zhang Laibin Liang Wei Wang Zhaohui | 2009 | Petroleum Science2009，6，2： | 8 |

| 4 | Safety prognostic technology in complex petroleum engineering systems: progress, challenges and emerging trends显示文摘Oil and gas facilities used in the petroleum industry can be considered as complex dynamic systems in that they require different types of equipment with various causal relationships among components and process variables under monitoring.As the systems grow increasingly large,high speed,automated and intelligent,the nonlinear relations among these process variables and their effects on accidents are to be fully understood for both system reliability and safety assurance.Failures that occur during the process can both cause tremendous loss to the petroleum industry and compromise product quality and affect the environment.Therefore,failures should be detected as soon as possible,and the root causes need to be identified so that corrections can be made in time to avoid further loss,which relate to the safety prognostic technology.By investigation of the relationship of accident causing factors in complex systems,new progress into diagnosis and prognostic technology from international research institutions is reviewed,and research highlights from China University of Petroleum(Beijing) in this area are also presented.By analyzing the present domestic and overseas research situations,the current problems and future directions in the fundamental research and engineering applications are proposed. | Zhang Laibin Hu Jinqiu | 2013 | Petroleum Science2013，10，4： | 5 |
| 5 | Boosted electromagnetic wave absorption performance from synergistic induced polarization of SiC_(NWs)@MnO_(2)@PPy heterostructures显示文摘In the last decade,electromagnetic pollution has caused people’s considerable attention.Developing absorbing material with low cost,lightweight,simple preparation,and high electromagnetic attenuation efficiency has become a feasible means to deal with this problem.In this work,core–shell SiC_(NWs)@MnO_(2)@PPy(NWs:nanowires,PPy:polypyrrole)heterostructures composed of SiC nanowires core,MnO_(2)nanosheets inter-layer,and PPy coating were successfully prepared through chemical vapor deposition and two-step electrodeposition process.Taking advantage of the interfacial polarization and dipole polarization,the obtained product displays excellent electromagnetic wave absorption performances with the minimum reflection loss(RLmin)of−50.59 dB when the matching thickness is 2.41 mm,and the optimal effective absorption bandwidth(EAB)value reaches to 6.64 GHz at a matching thickness of 2.46 mm,revealing that the SiC_(NWs)@MnO_(2)@PPy nanocomposite could be served as a promising electromagnetic wave absorbing material.On the basis of systematic analysis concerning the electromagnetic parameters,the dissipation process of the incident electromagnetic wave was demonstrated reasonably,which may provide a referable preparation strategy for novel heterostructures,especially nonmagnetic lightweight absorbing material. | Meng Zhang Laibin Zhao Wenxin Zhao Ting Wang Liying Yuan Yuying Guo Yuxin Xie Tingting Cheng Alan Meng Zhenjiang Li | 2023 | Nano Research2023，16，2： | 4 |
| 6 | Application of an Improved ISODATA Method to Pipeline Leak Detection显示文摘Increasingly serious leak problem in pipeline transportation has not only affected the operation of pipelines but also caused loss of precious resource and environmental damage. Based on the analysis of the occurrence of negative pressure waves and the unsupervised learning of pattern recognition, the Interactive Self-organizing Data Analysis Technique Algorithm (ISODATA) method was used to classify the negative pressure waves and then the states of pipelines could be determined. K_L transformation was used to eliminate the correlativity of feature parameters and to reduce the dimensionality of feature vector space to speed up calculation. Experimental results validated the accuracy and practical value of this method. | Hu Jinqiu Zhang Laibin Wang Zhaohui Liang Wei | 2007 | Petroleum Science2007，4，2： | 4 |
| 7 | Experimental study ofcasing wear under impact-sliding conditions显示文摘Theoretical analysis and field monitoring show that lateral vibration has very important effect on casing wear in deep & ultra-deep well drilling.The wear mechanism ofcasing under impact-sliding work conditions has been investigated and many experiments have been completed with a newly developed full-scale casing wear test machine.Test results present that adhesion wear,contact fatigue,and grinding abrasion are the main wear mechanisms under impact-sliding test conditions.The friction coefficient and linear wear rate ofthe casing rise obviously with an increase in impact load.And the larger the impact load,the rougher the worn surface ofthe casing.The linear wear rate decreased slightly but the average friction coefficient increased slightly with an increase in impact frequency under an impact load of2,500 N.Both the linear wear rate ofthe casing and the average friction coefficient increased substantially with an increase in impact frequency under an impact load of4,000 N.Under lower impact load conditions,grinding abrasion and contact fatigue are the main mechanisms ofcasing wear;under higher impact load conditions,adhesion wear and contact fatigue are the main mechanisms ofcasing wear. | Shengli Chu Laibin Zhang Jianchun Fan Wenpei Zheng Huiyuan Yu | 2009 | Petroleum Science2009，6，4： | 3 |
| 8 | An Equivalent Substitute Strategy for Constructing 3D Ordered Porous Carbon Foams and Their Electromagnetic Attenuation Mechanism显示文摘Three-dimensional(3D)ordered porous carbon is generally believed to be a promising electromagnetic wave(EMW)absorbing material.However,most research works targeted performance improvement of 3D ordered porous carbon,and the specific attenuation mechanism is still ambiguous.Therefore,in this work,a novel ultra-light egg-derived porous carbon foam(EDCF)structure has been successfully constructed by a simple carbonization combined with the silica microsphere template-etching process.Based on an equivalent substitute strategy,the influence of pore volume and specific surface area on the electromagnetic parameters and EMW absorption properties of the EDCF products was confirmed respectively by adjusting the addition content and diameter of silica microspheres.As a primary attenuation mode,the dielectric loss originates from the comprehensive effect of conduction loss and polarization loss in S-band and C band,and the value is dominated by polarization loss in X band and Ku band,which is obviously greater than that of conduction loss.Furthermore,in all samples,the largest effective absorption bandwidth of EDCF-3 is 7.12 GHz under the thickness of 2.13 mm with the filling content of approximately 5 wt%,covering the whole Ku band.Meanwhile,the EDCF-7 sample with optimized pore volume and specific surface area achieves minimum reflection loss(RL_(min))of−58.08 dB at 16.86 GHz while the thickness is 1.27 mm.The outstanding research results not only provide a novel insight into enhancement of EMW absorption properties but also clarify the dominant dissipation mechanism for the porous carbon-based absorber from the perspective of objective experiments. | Meng Zhang Hailong Ling Ting Wang Yingjing Jiang Guanying Song Wen Zhao Laibin Zhao Tingting Cheng Yuxin Xie Yuying Guo Wenxin Zhao Liying Yuan Alan Meng Zhenjiang Li | 2022 | Nano-Micro Letters2022，14，10： | 3 |

| 10 | Soil Nutrient Distribution in Two Typical Paddy Terrace Wetlands Along an Elevation Gradient During the Fallow Period显示文摘Soil nutrient concentrations in the top soils from two paddy terraces were determined in order to investigate spatial distributions of soil nutrients along the elevations on the Yunnan plateau of China during the fallow period.Results showed that soil nutrients in both terraces were higher than the reference concentrations except for SOC,TN,TP and Fe.Soil macronutrients didn't show significant differences in both terraces except for Mg and Ca,so did soil micronutrients except for Mn.Spatial distribution patterns of soil nutrients along the increasing elevations were different in both terraces.However,soil nutrients in both terraces were generally not significantly influenced by the elevations and soil pH values.The findings of this study can contribute to soil fertility management and ecological protection of Hani terraces. | WANG Qinggai BAI Junhong HUANG Laibin DENG Wei XIAO Rong ZHANG Kejiang | 2011 | Journal of Mountain Science2011，8，3： | 2 |
| 11 | Relationship between Formation Water Rate,Equivalent Penetration Rate and Volume Flow Rate of Air in Air Drilling显示文摘Formation water invasion is the most troublesome problem associated with air drilling. However,it is not economical to apply mist drilling when only a small amount of water flows into wellbore from formation during air drilling. Formation water could be circulated out of the wellbore through increasing the gas injection rate. In this paper,the Angel model was modified by introducing Nikurade friction factor for the flow in coarse open holes and translating formation water rate into equivalent penetration rate. Thus the distribution of annular pressure and the relationship between minimum air injection rate and formation water rate were obtained. Real data verification indicated that the modified model is more accurate than the Angel model and can provide useful information for air drilling. | Wang Kexiong Zhang Laibin Jiang Hongwei | 2007 | Petroleum Science2007，4，4： | 2 |

| 14 | Predicting vibration signals of automobile engine using chaos theory显示文摘Condition monitoring and life prediction of the vehicle engine is an important and urgent problem during the vehicle development process. The vibration signals that are closely associated with the engine running condition and its development trend are complex and nonlinear. The chaos theory is used to treat the nonlinear dynamical system recently. A novel chaos method in conjunction with SVD (singular value decomposition)denoising skill are used to predict the vibration time series. Two types of time series and their prediction errors are provided to illustrate the practical utility of the method. | LIU Chun ZHANG Laibin WANG Zhaohui | 2004 | Science China(Physics,Mechanics & Astronomy)2004，47，z1： | 1 |
