| 1 | Characteristics and accumulation mechanism of tight sandstone gas reservoirs in the Upper Paleozoic, northern Ordos Basin, China显示文摘The Ordos Basin is a significant petroliferous basin in the central part of China.The Carboniferous and Permian deposits of transitional and continental facies are the main gas-bearing layers in the north part of the basin.The Carboniferous and Permian natural gas reservoirs in the northern Ordos Basin are mainly tight sandstone reservoirs with low porosity and low permeability,developing lots of 'sweet spots' with comparatively high porosity and permeability.The tight sandstones in the study area are gas-bearing,and the sweet spots are rich in gas.Sweet spots and tight sandstones are connected rather than being separated by an interface seal.Sweet spot sand bodies are vertically and horizontally overlapped,forming a large gas reservoir group.In fact,a reservoir formed by a single sweet spot sand body is an open gas accumulation.In the gentle dipping geological setting and with the source rocks directly beneath the tight reservoirs over a large area,the balance between gas charging into tight reservoirs from source rocks and gas loss from tight reservoirs through caprock is the key of gas accumulation in tight sandstones.Both the non-Darcy flow charging driven by source-reservoir excess pressure difference and the diffusion flow charging driven by source-reservoir gas concentration difference play an important role in gas accumulation.The results of mathematical modeling indicate that the gas accumulation cannot be formed by just one of the above mechanisms.The diffusion of gas from source rocks to reservoirs is a significant mechanism of tight sandstone gas accumulation. | Liu Guangdi Sun Mingliang Zhao Zhongying Wang Xiaobo Wu Shenghe | 2013 | Petroleum Science2013，10，4： | 16 |

| 11 | A NOVEL SPACE-COMPRESSED CHINESE WORD DIGRAM BASED ON BI-CHARACTER CO-ARTICULATION FREQUENCY显示文摘Chinese Phonetic-Character Conversion(CPCC) is an important issue in Chinese speech recognition and Chinese sentence keyboard input system. The approaches based on large corpus statistic Markov language model (such as bigram, trigram) become more and more popular today. This paper presents an improved Chinese word bigram, space-compressed Chinese word bigram, which stores the bi-word co-articulation frequency in the form of the bi-character co-articulation frequency. The bi-word co-articulation frequency is estimated from the bi-character co-articulation frequency library. The CPCC experiment with the improved Chinese word bigram shows: it can reach a higher correct conversion ratio with less space occupation. | Zhao Yibao Qiao Liyan Tan Jianxun Sun Shenghe(Automatic Test and Control Department, Harbin Institute of Technology, Harbin 150001) (Robot Research Institute, Harbin Institute of Technology, Harbin 150001) | 2000 | Journal of Electronics(China)2000，17，2： | 1 |
