利用系统分析方法进行单井措施优选

油井措施增油一直是油田控制产量递减、含水上升的主要做法，但是随着油田开采程度加深，地下油水分布十分复杂，选择油水井措施难度越来越大。为此，运用系统分析方法进行单井措施优选，通过对区块水驱油、水驱水、井间干扰以及油井的液、油、含水率间关系，综合判断出区块内滞留区、死油区和动用好的区域，指出今后挖潜方向。此方法均应用动态数据，客观性较强、准确性较高，克服了以往选择单井措施的盲目性和主观性。并将该方法在大庆油田杏八、九区基础井网提液试验过程中得到应用，效果较好。     

Cif2000平台下的核磁共振测井解谱方法研究

介绍了在Cif2000多井解释平台下的核磁共振解谱方法与编程实现。解谱采用加入平滑因子后在特征矩阵的奇异值分解中截去小的非零奇异值的方法，可以在低信噪比时得到稳定的弛豫谱，在油田实际应用中证明了该方法的有效性。根据该方法在Cif2000平台上编制了完整的解谱处理程序，可以直接用于油田的生产实际。

Evaluation of mathematical equations to predict the theoretical yield of Chilean Gouda cheese

This study was performed to obtain an adequate tool for predicting the yield of Chilean Gouda cheese. The theoretical yields were calculated by applying equations derived from technical references to industrial cheese production and were compared with their own actual yields, thus selecting those equations showing the best correlation with the actual yield.
The manufacturing and ripening of the cheese were controlled through the chemical composition of milk, whey and cheese, and the weight of the product before and after ripening was recorded.
The actual and theoretical yield values derived from each formula were compared using the mean yield graphs. Furthermore, the global concordance coefficient ( W ) of Kendall and Smith was also applied, showing the lack of significant discrepancy between actual and theoretical yield values [ P  > 0.01 ( W  = 27; W ≥  18.48)] for either 3- or 30-day cheeses. Out of the 11 formulae used to measure the yield of cheese, six showing a good correlation between the yields were selected through the comparison of error sums and Pearson correlation analysis. However, two formulae showed the best yield results for practical use.

Preparation, Characterisation and Catalytic Behaviour of a New TeVMoO Crystalline Phase

TeM_xMo_1.7O mixed oxides (M = V and/or Nb; x = 0-1.7) have been prepared by calcination of the corresponding salts at 600 °C in an atmosphere of N₂. A new crystalline phase, with a Te/V/Mo atomic ratio of 1/0.2-1.5/1.7, has been isolated and characterised by XRD and IR spectroscopy. This phase is observed in the TeVMo or TeVNbMo mixed oxide but not in the TeNbMo mixed oxide. The new crystalline phase shows an XRD pattern similar to Sb₄Mo₁₀O₃₁ and probably corresponds to the M1 phase recently proposed by Aouine et al. (Chem. Commun. 1180, 2001) to be present in the active and selective MoVTeNbO catalysts. Although these catalysts present a very low activity in the propane oxidation, they are active and selective in the oxidation of propene to acrolein and/or acrylic acid. However, the product distribution depends on the catalyst composition. Acrolein or acrylic acid can be selectively obtained from propene on Nb-free or Nb-containing TeVMo catalysts, respectively. The presence of both V and Nb, in addition to Mo and Te, appears to be important in the formation of acrylic acid from propene.
