圈闭含油气最优化综合定量评价法

从含油气系统理论出发，将圈闭成藏的地质条件分为５个单项地质条件及１８个子项因素，并以子项因素建立圈闭基础数据库；然后，确定各子项因素的评价标准，从而实现其评价的定量化；由专家打分定量给出已钻探圈闭的各项地质条件的评价，由此回归出评价曲线，得到未钻探圈闭的定量评价；最后，利用已钻探圈闭的含油气情况，通过一种最优化方法，对未钻探圈闭的含油气情况作出定量的评价。用大庆长垣南地区的实际资料验证表明，本方法

油气评价系统中传统圈闭地质模型建立时的“生、储、盖、运、圈、保”可以分成三个层次：①圈闭获得油气的能力；②圈闭的储集能力；③圈闭的后期保存条件。这三个层次构成圈闭地质建模的“三要素”，依据不同的地质条件，其侧重点不同。在对圈闭模型参数赋值、计算得到圈闭含油气性系数的基础上，结合圈闭可靠性评价结果，便可以得到圈闭的成藏系数或圈闭的地质风险系数。

Experiments in support of the Gas Dynamic Trap based facility for plasma–material interaction testing

The power density along the field lines in the scrape-off layer plasma in machines of the class of ITER, Wendelstein 7-X, NSTX-U is in the range of few hundreds megawatt per square meter. It is crucial for the future of tokamaks and stellarators to develop the plasma science and component technology to handle such high plasma heat fluxes. It would be valuable to produce parallel plasma heat fluxes at these power densities, impinging on test components at very shallow angles, as planned in tokamaks. The primary objective of this work is the direct measurement of plasma heat fluxes in the mirror throat of a Gas Dynamic Trap device. Options to develop a facility for plasma–material interaction testing based on the Gas Dynamic Trap are discussed.     

New concept for soot removal from a syngas mixture

A new concept for soot removal from inside a syngas environment has been studied. Particulate emissions are retained in a soot trap downstream from a thermal partial oxidation (TPOX) reformer, while the syngas atmosphere itself is utilized as a gasification agent to achieve continuous and passive trap regeneration. This work analyses the performances of the loading and the regenerating phases of a wall flow soot trap in a syngas environment in an ad hoc developed test rig. A balance point between filtered and removed soot was actually reached at trap temperatures in the 800-1000 °C range with soot abatement efficiencies above 95 wt%. The particulate is obtained from a TPOX reactor operating in very rich fuel conditions, using methane as fuel. The final application of the reactor and trap assembly is a micro CHP system, based on an SOFC fed by a TPOX reformer. However, application to larger contexts (e.g. biomass gasification plants) can be envisaged.     

圈闭地质评价中模糊数学综合评判法的优势

以光老化试样验证聚烯烃击穿的陷阱理论

在聚合物电老化击穿的陷阱理论中，介电强度与陷阱密度呈函数关系，这已在电老化试样上得到证实。本文用光辐射改变试样的陷阱密度，从光降解动力学推导其变化规律。在光老化过程中，同时测量聚丙烯试样的击穿电压、自由基浓度、微孔的变化和陷阱密度。试验结果表明，陷阱密度的变化直接反映着试样微观结构的变化，陷阱密度和介电强度的变化规律符合理论分析。     

柴油机用纤维颗粒捕集器的压力损失研究

钢丝纤维捕集器是一种简单、有效的柴油机尾气颗粒排放收集装置。捕集效率和压力损失是其两个最重要的性能指标。捕集器压力损失标志了捕集器纤维对流体流动的阻碍的程度，它导致柴油机排气背压上升。当压力降超过一定范围，会引起柴油机工作情况明显恶化。为此，本文结合了模拟实验和量纲分析，提出了这种纤维过滤器的一个简易实用的压降损失经验表达式。它可以较为准确地预测纤维颗粒捕集器的压力损失特性，为优化设计纤维颗粒捕集器提供了可靠的基础。
