In this paper, we attempt to differentiate hydrocarbon‐bearing reservoir horizons of the Junggar Basin of NW China based on the characteristics of diagenesis and associated elemental geochemistry. Reservoirs at this site have varying levels of oil saturation that correlate with the degree of dissolution in minerals (e.g., calcite and feldspar). Four different horizons with varying diagenetic mineral assemblages were observed, including (i) kaolinite‐rich, oil‐dominated horizons, (ii) kaolinite–pyrite–hematite‐rich, oil–water‐dominated horizons, (iii) siderite–chlorite‐rich, water‐dominated horizons, and (iv) chlorite‐rich horizons with negligible hydrocarbon production. The mean MnO content of the representative diagenetic mineral (e.g., calcite) in each of the above horizons is >2.5, 2.0–2.5, 1.5–2.0, and <1.0 wt%, respectively. We propose that the above methodology can be used for the identification of reservoir hydrocarbon‐bearing horizons. We argue that the indicators presented here can be applied in oil exploration across the Junggar Basin. 相似文献

We propose a new methodology based on standard statistical processes for displaying and rigorously comparing the alloy composition of archaeological bronze alloys. Although traditional approaches using visual comparisons of histograms of alloying elements in an assemblage of archaeological objects are adequate for observing differences between these distributions, we argue that differences in sample size cannot be adequately accounted for without using a statistical approach. We demonstrate this methodology by comparing the alloy composition of bronzes from the sequence of Bronze Age cultures in Central China—Erlitou, Erligang (Zhengzhou, or early Shang), Anyang (late Shang) and Western Zhou. We suggest that this approach allows the identification and rigorous comparison of ‘regional alloying practices’, which in turn enables us to link the alloy composition of the objects with the intentions and skills of foundry workers. 相似文献

ABSTRACTThis paper develops a nuanced understanding of town-country relations in China. Inherent in the current literature is the serious problem of randomly indigenizing experiences and concepts from the West. To restore this imbalance, this paper provides a preliminary attempt to develop a better understanding methodologically, epistemologically and theoretically. It argues first for the implementation of a spatial story methodology that takes spatio-temporal relations seriously; second, a nuanced concept of the state as dynastic empire-building which functions through a two-tier governing relationship in focus-field relationships; third, a rejection of dualism, advocating instead the idea of mutual embeddedness in order to decipher the subtle relationships between parts and whole; fourth, an interrogation of the appropriateness of spatial concepts like spatial reach, scale, level and territory; and, finally, a proposed concept of cheng-cum-xiang to eschew a dualistic approach to town-country relations. In conclusion, the paper suggests implications for debates within urban studies more generally. 相似文献

The globalisation of retailing has intensified since the mid‐1990s with the rise of a group of international retailers. Foreign retailers have greatly impacted the Chinese retail market since the opening up of the retail sector in 1992. This study aims to examine spatial inequality and dynamics of foreign hypermarket retailers at different geographic scales in China. Although the relative gaps in foreign hypermarkets among Chinese regions are narrowing, the absolute gaps are widening. Logistic regression models are used to identify locational determinants of foreign retailers Carrefour, Wal‐Mart, and RT‐Mart at the intercity level. Carrefour prefers cities with larger urban district populations, longer time of being open to international retailers, and more foreign investment. While urban district populations are significant to Wal‐Mart and RT‐Mart as well, they favour cities where people have higher annual salaries and aim to achieve internal economies of scale at the provincial level. The three leading foreign retailers also have different first‐city and city size preferences in their provincial expansions. 相似文献
