量子自旋霍尔绝缘体拥有具有带隙的体态和无能隙的一维拓扑边缘态.然而,由于拓扑边缘态局域在纳米尺度,所以很难用光学手段直接观测并区分体态和边缘态,这就限制了对拓扑边缘态独特的光学特性和光电响应等方面的研究和应用.Bi_(4)Br_(4)体材料的台阶存在一维非平庸的边缘态,多个台阶累加的效应使得通过较为宏观的光学和光电分析手段来研究一维边缘态成为可能.该工作利用中远红外显微吸收光谱和泵浦探测光谱,对比研究了Bi_(4)Br_(4)体和边缘的光学响应行为.研究发现Bi_(4)Br_(4)的边缘在小于带隙(约0.22 eV)的波段存在明显的强于体内的红外吸收,且该吸收呈现较强的各向异性.室温下的红外泵浦探测首次观察到边缘处载流子激发态超长的弛豫时间(1.5 ns),该激发态载流子寿命要比体内载流子寿命长两个量级.该工作证实体态和拓扑边缘态具有明显不同的光学和光电响应行为,为未来设计新型红外探测器提供了材料和物理基础.

煤基质收缩使储层裂隙孔隙度和渗透率发生很大变化,目前的研究方法普遍存在测量费用昂贵和计算误差大的问题。文章基于固体变形理论与固体表面能理论,建立了一个新的煤基质收缩变形对煤裂隙渗透率和孔隙度影响的数学模型,消除了直接用煤体收缩系数来计算煤裂隙孔隙度和渗透率所引起的误差。研究结果表明,煤基质收缩引起裂隙渗透率变化经历了一个先降低后升高的趋势;裂隙的渗透率增大与储层压力的降低呈对数变化关系;煤层气中Langmuir体积大的气体所占的相对密度越大,解吸后煤储层裂隙的孔隙度和渗透率的变化越大。最后,通过实例计算分析对比,模型能准确合理地反映煤基质收缩变形对煤裂隙渗透率和孔隙度变化的影响。

作者：严文德郭肖孙雷西南石油大学"油气藏地质及开发工程"国家重点实验室

低渗透气藏普遍具有低孔、低渗、高含水饱和度的特点,因而往往具有较高的启动压力梯度。目前,在进行低渗透气井产能预测时,多采用常规气藏的产能预测公式,启动压力梯度被忽略,导致预测结果与生产实际存在较大误差。通过大量文献的调研,... 详细信息

低渗透气藏普遍具有低孔、低渗、高含水饱和度的特点,因而往往具有较高的启动压力梯度。目前,在进行低渗透气井产能预测时,多采用常规气藏的产能预测公式,启动压力梯度被忽略,导致预测结果与生产实际存在较大误差。通过大量文献的调研,确认低渗透气藏中启动压力梯度确实存在,并且已逐渐成为产能预测中一个不容忽视的重要影响因素。为此,文章基于对低渗透气藏渗流机理的分析和研究,利用Forchheimer由实验提出的描述气体渗流的压降二次方程,同时考虑启动压力梯度的影响,推导出了适合低渗透气藏的气井产能预测公式,并对其进行了实例计算分析,认为低渗透气藏产能预测中必须考虑启动压力梯度的影响,得到了进行产能预测时一些必要参数的获取方法。

通过分析影响复合地基桩土应力的因素,指出复合地基的桩土应力与垫层刚度、桩间土刚度、桩刚度的大小有关。从荷载试验应力-变形曲线入手,利用荷载试验能从宏观上反映桩土相互作用的特点,提出考虑垫层刚度、桩间土刚度、桩刚度的多桩型复合地基桩土应力的计算方法;指出多桩型复合地基设计应将主;辅桩设计为两道防线,主桩为第一道防线,主要目的是减小复合地基沉降,设计时宜采用刚度较大的桩体;辅桩为第二道防线,主要保证复合地基的安全度、调整主桩的应力,设计时宜采用柔性桩或者刚度较小的桩。垫层厚度的调整对桩土应力影响较大,但对应力发挥顺序影响不大。通过分析得到:多桩型复合地基的设计应全面看待各刚度的影响,根据实际问题,调整主、辅桩和土的刚度以及垫层的厚度。后续研究应集中在建立合理的复合地基的评价机制上。
