塔河油田于奇地区奥陶系碳酸盐岩岩溶作用研究

塔河油田北部于奇地区经多期构造运动,岩溶储层发育不均。从岩心观察、薄片鉴定、钻井和录井资料及测井、地震资料等方面进行分析解释,论述于奇地区奥陶系碳酸盐岩多期岩溶作用的存在依据和发育特征,总结同生、表生期大气水裸露风化壳型岩溶作用和侵蚀埋藏岩溶作用模式。结果表明:研究区西南部岩溶斜坡集中发育岩溶缝孔洞和洞穴,北部岩溶高地溶蚀作用不强,岩溶缝孔洞相对较少。于奇地区主要经历了加里东中晚期表生大气水岩溶作用、海西早期同生岩溶作用及海西期埋藏岩溶作用。     

The Uplift of the Longmenshan Thrust Belt and Subsidence of the West Sichuan Foreland Basin

Based on fission track dating of apatite, and measurement of vitrinite reflectance of rock samples from the Longmenshan (Longmen Mountain)area and the West Sichuan foreland basin and computer modelling it is concluded that (l)the Songpan-Garze fold belt has uplifted at least by 3-4 km with an uplift rate of no less than 0.3-0.4 mm/a since 10 Ma B.P.; (2) the Longmenshan thrust nappe belt has uplifted at least by 5-6 km with an uplift rate of more than 0.5- 0.6 mm /a since 10 Ma B.P.; (3) the Longmenshan detachment belt has uplifted by 1 - 2 km at a rate of 0.016-0.032 mm/a since 60 Ma B.P.; (4) the West Sichuan foreland basin has uplifted by 1.7-3 km at a rate of 0.028-0.05 mm/a since 60 Ma B.P.; (5) the uplift rate of the area on the west side of the Beichuan-Yingxiu-Xiaoguanzi fault for the last 10 Ma is 40 times as much as that on its east side; (6) the uplifting of the the Songpan - Garze fold belt and the subsidence of the West Sichuan foreland basin 60 Ma ago exhibit a mirro-image correlation, i.e     

用于风电场功率预测的逐时风速预报

为满足风电场精细化风速预报的需要,利用MM5模式的格点输出数值预报产品以及福建沿海地区两座海上测风塔的逐时气象资料,采用逐步回归的统计方法,将MM5数值预报产品与测风塔实测气象资料要素指标值共同引入回归方程,拟合两座测风塔特定高度的逐小时风速预报方程,详细介绍了该方法的实现过程.通过一年的预报效果指标以及15日的独立样本效果检验,结果表明该方法对于逐小时风速的预报有一定的应用价值.     

Indium Enrichment in the Meng'entaolegai Ag-Pb-Zn Deposit, Inner Mongolia, China

Abstract. The Meng'entaolegai In-rich Ag-Pb-Zn deposit is located in the eastern part of Inner Mongolia. It is one of the In-richest deposits in China. Large amounts of quartz and sulfide minerals constitute a hydrothermal quartz-sulfide vein deposit within a Hercynian acidic granite massif, which occupies an area of about 400 km². Thirty-six orebodies, controlled strictly by the E-W trend faults, are found in the orefield of 6 km in length from east to west and 200 to 1,000 m in width from south to north. The ore minerals are mainly galena, sphalerite and pyrite, and subordinate chalcopyrite, arsenopyrite, cassiterite and stannite with many Ag-minerals. The gangue minerals are mainly quartz, calcite, sericite and chlorite. Economic components of the deposit are dominated by Pb andZn (reserves of Pb and Zn are 0.17 Mt and 0.37 Mt, and their grades are 1 % and 2.3 %, respectively), with Ag, Sn, In and Cd (1,800 t Ag, >2,000 t Sn, >500 t In and 1,800 t Cd) as by-products. Indium is highly enriched in ores and its contents are 9 to 295 ppm in ores and 85 to 2,660 ppm in sphalerite. Analytical results show that the ore-forming fluid of this deposit contains 0.8–3.5 ppm In and 4–36 ppm Sn, and the two elements show a very good positive correlation with a correlation coefficient of 0.8672, while the correlation between In and Zn in the ore-forming fluids, with a correlation coefficient of 0.5723, is not as good as that between In and Sn. This indicates that indium has an affinity with tin in the ore-forming fluids. The authors think that this is probably the main reason why those In-rich deposits spread over the world are simultaneously enriched in tin.
