| 1 | Caledonian reworking of Paleoproterozoic basement in the Cathaysia Block: Constraints from zircon U-Pb dating, Hf isotopes and trace elements显示文摘A combined study of zircon U-Pb dating, Hf isotopes and trace elements has been carried out for granodioritic neosomes of migmatites from the Tianjingping area in northwestern Fujian Province. Zircons are characterized by zoning, higher Th/U ratios (mostly ≥0.1), HREE enrichment, and positive Ce and negative Eu anomalies, and show features similar to magmatic or anatectic zircons. Apparent 206Pb/238U ages for the zircons are 447±2 Ma (95% conf., MSWD = 0.88), corresponding to a Caledonian event. εHf(t) values are ?13.3 to ?9.7, indicating a crustal source. Two-stage Hf model ages are 1.7 to 1.9 Ga, suggesting that protolith of the migmates was probably formed in the Paleoproterozoic. The granodioritic neosomes have the characteristics of peraluminous calc-alkaline granite, and their REE patterns and trace elements spidergrams show features of middle to upper crustal rocks. Together with previous studies, we conclude that the protolith of the Cathaysia basement in the Tianjingping area was likely formed in the middle-late Paleoproterozoic and experienced partial melting during the Caledonian period. The recognition of Caledonian reworking of the Paleoproterozoic basement in the Cathaysia Block provides a new insight into the tectonic evolution of the Cathaysia Block in the Caledonian pe- riod and the interaction between the Cathaysia Block and the Yangtze Block. | ZENG Wen ZHANG Li ZHOU HanWen ZHONG ZengQiu XIANG Hua LIU Rui JIN Song LU XinQian LI ChunZhong | 2008 | Chinese Science Bulletin2008，53，6： | 21 |
| 2 | Mathematical model study on the damage of the liquid phase to productivity in the gas reservoir with a bottom water zone显示文摘The production process in the gas reservoir with an aquifer is complex.With gas production,aquifer water could possibly flow into the production well and accumulate within the well bore,which leads to a lower production rate and may even block the producer.However,few studies in the literature investigate the damage caused by the liquid phase in this kind of reservoir or predict gas productivity using the relationship between reservoir pressure and water gas ratio(WGR).For this reason,it is important to know the effects of the formation of liquid phase behavior on production when an aquifer is present under a gas reservoir.From the results of published literature reviews,we found that studies focused on the production of a gas reservoir with bottom water.Nevertheless,for gas well damage from the liquid phase behavior,we found that there was no statistical data or mathematical model of the relationship between reservoir pressure and the gas oil ratio(GOR),which affects production.In this research,based on the theory of fluid flow in porous media,a new mathematical model of water and gas production and a new equation on gas well productivity is developed.To verify the model and equation,gas production data collected from the field are applied.By analyzing the typical gas reservoir with bottom water and the collected data,influences from the liquid phase behavior are shown.In this way,mathematical relationships between reservoir pressure and the WGR and between the GOR and production decline were obtained.The new gas productivity model is derived from the gas and water pseudo pressure functions,which can be applied to analyze well damage caused by the liquid phase.In order to verify the mathematical model,production data were collected from a typical gas reservoir with an aquifer located in the Changxing gas reservoir.The results indicate that a semi-logarithmic linear relationship is obtained between the WGR and productivity decrease.When the WGR increases from 0.5 to 15m3/104m3,damage caused by liquid phase decreases to 59%.The tendency of gas productivity in the Changxing gas reservoir was obtained so that it decreases as reservoir pressure decreases and increases as the WGR decreases.The gradient of the gas productivity deduction increases as the WGR increases.By the end of the data analysis,two linear equations indicating the relationship between gas productivity and reservoir pressure and the relationship between gas productivity and the water gas ratio are obtained:QAOF?A1lnWGRB1 and QAOF?A2lnPB2,respectively. | Xiaoliang Huang Xiao Guo Xinqian Lu Xiang Zhou Zhilin Qi Wende Yan Jiqiang Li | 2018 | Petroleum2018，4，2： | 4 |
