Reservoir prediction using multi-wave seismic attributes

引用

Earthquake Science 2011年第4期24卷 373-389页

作者： Ye Yuan Yang Liu jingyu zhang Xiucheng Wei Tiansheng Chen State Key Laboratory of Petroleum Resources and Prospecting China University of Petroleum Beijing 102249 China CNPC Key Laboratory of Geophysical Prospecting China University of Petroleum Beijing 102249 China Petroleum Exploration and Production Research Institute SINOPEC Beijing 100083 China

The main problems in seismic attribute technology are the redundancy of data and the uncertainty of attributes, and these problems become much more serious in multi-wave seismic exploration. Data redundancy will increase the burden on interpreters, occupy large computer memory, take much more computing time, conceal the effective information, and especially cause the ＂curse of dimension＂. Uncertainty of attributes will reduce the accuracy of rebuilding the relationship between attributes and geological significance. In order to solve these problems, we study methods of principal component analysis （PCA）, independent component analysis （ICA） for attribute optimization and support vector machine （SVM） for reservoir prediction. We propose a flow chart of multi-wave seismic attribute process and further apply it to multi-wave seismic reservoir prediction. The processing results of real seismic data demonstrate that reservoir prediction based on combination of PP- and PS-wave attributes, compared with that based on traditional PP-wave attributes, can improve the prediction accuracy.

Mechanism and effects of snow accumulations and controls by lightweight snow fences

引用

Journal of Modern Transportation 2016年第4期24卷 261-269页

作者： Duote Liu Yongle Li Bin Wang Peng Hu jingyu zhang Department of Bridge Engineering Southwest Jiaotong University Department of Bridge Engineering Changsha University of Science and Technology

This paper investigates the snowdrifts caused by lightweight fences along the lines on the flatland through the computational fluid dynamics method. The characteristic ambient flows around the solid fences and the porous fences with varied heights and bottom wind gaps are simulated in the numerical model, and the working mechanism of ＂interception＂ and ＂scouring＂ of the lightweight fences are analyzed. Based on the friction velocities near the ground, two sets of criteria are proposed to evaluate the deposition and erosion effects of different fences. According to flow separation and reattachment, the simplified relationships between the most likely positions for snow accumulations and fence parameters are devel- oped. The study indicates that the capabilities for snow interception by the solid fence without wind gap and the distance from which to the second snow coverage center both increase with the fence height. Furthermore, it is found that the scouring range for snow surface increases significantly with the size of wind gap, and the snow accumulation rate on the leeward side decreases with the increasing fence porosity.
