, 2017 页岩气储层体积压裂后进行注气开采时提高页岩采收率的重要手段之一,进行页岩气注CO_2开发数值模拟是明确页岩气储层注CO_2开发增产机制,优化注入工艺方案的关键。基于页岩气储层双重介质地质特征,且考虑页岩孔隙度和渗透率的应力敏感性,建立了页岩气注气开采多组分气体扩散和流动控制方程组,并进行数值模拟,分析了不同注气组分和渗透率敏感性对页岩气产量的影响。结果表明:注CO_2比未注CO_2开采的产气量有显著提升,且应力敏感性对产量预测结果影响较大,CO_2注入组分等因素也会对日产量产生影响 ...

A DFT Study on C-H Bond Activation of Methane by CeO2 and CeO2-doped with Metal Cations [PDF]
, 2015 甲烷是天然气的主要成分，是燃料和化学品中非常出色的原材料，但甲烷又是非常稳定的分子，其活化常需较高的温度，因此，研究有效活化甲烷，特别是较低温下转化甲烷的催化剂，具有理论和实际的研究意义。近年来，研究表明二氧化铈基纳米催化剂具有良好的低温活化甲烷性能，但其活性中心本质和活化机理尚不很清楚。为此，我们采用密度泛函理论(DFT)方法，对二氧化铈及掺杂不同金属阳离子的二氧化铈体系活化甲烷C-H进行了计算研究。其主要研究内容和结果如下： 1.以(CeO2)m(m=1-3)团簇为模型对甲烷C ...

China's Green Economic Growth and the Corresponding Energy Transformation [PDF]
, 2016 资源耗竭和环境污染已经成为中国可持续发展的严重制约，特别是雾霾等环境问题的大面积集中爆发，更是将这一问题摆在了公众和政府的面前。但是，对于中国这样的发展中大国，“发展是第一要务”，因为解决十三亿人口的吃饭和就业问题都离不开经济较快增长。如何在稳增长、资源节约、环境友好这三者之间的权衡取舍是政府面临的难题。因此，对于中国社会经济的可持续发展，关键是在兼顾经济增长的同时尽可能实现资源节约和环境改善。这就需要实现绿色经济增长的转型。 另一方面，气候目标成为中国经济发展的约束条件 ...
