运移路径模拟和应用尝试

油气二次运移的方式和方向对具体指出盆地油气资源量所赋存的位置有决定性的意义.在运载层中推动油气运动的作用力主要是浮力和毛细管力,而盖层则起着毛细管阻力作用.因此盖层的形状及空间分布就成了影响运移路径重要的封盖因素.该文试图根据盖层的几何形状特性,建立运移路径模拟模型,开发微机软件运行实施.在一个具体盆地进行运移路径模拟应用的结果反映,与已知勘探情况基本符合,能够检验油气期次性运移的地质概念,可以揭示运移过程,预测可能的运移聚集位置.      

构造作用对油气生成和运聚的影响

有机质从埋藏开始，就处于极其复杂的地球物理化学场中，环境提的能量，一是热量，二是机械能，机械能，主要是通过机械力作用传递给系统的，另外还以机械波的形式赋予系统一定的机械能。当发生断褶构造运动时，机械力对油气运移的影响尤为突出，它经能量的迁移转化，促成了包括机械力降解和地应力驱动等一系列的连锁反应，制造了一次次高效的成油（生运）事件，本文以突变论为着眼点，按照改造控制建造的思路，大胆提出构造运动制造生排烃事件，成就含油气系统的假说。     

复杂地区三维叠前时间偏移技术的应用

在常规地震数据处理过程中，反射波的偏移成像是基于地震数据的共深度点或共中心点叠加技术进行的，在地下地质构造相对复杂的地区，由于叠加过程的引入，导致了一些来自于大倾角地层或细微地质现象产生的地震反射信息的畸变或损失，而目前在算法上已经较为成熟的叠前偏移成像技术，便弥补了叠后偏移成像的不足，特别是在山前复杂构造区带，叠前偏移不仅能够使反射波准确成像，而且能够改善地震数据的信噪比和分辨率。

Signal analysis of total internal reflection fluorescent speckle microscopy (TIR-FSM) and wide-field epi-fluorescence FSM of the actin cytoskeleton and focal adhesions in living cells

Fluorescent speckle microscopy (FSM) uses low levels of fluorescent proteins to create fluorescent speckles on cytoskeletal polymers in high‐resolution fluorescence images of living cells. The dynamics of speckles over time encode subunit turnover and motion of the cytoskeletal polymers. We sought to improve on current FSM technology by first expanding it to study the dynamics of a non‐polymeric macromolecular assembly, using focal adhesions as a test case, and second, to exploit for FSM the high contrast afforded by total internal reflection fluorescence microscopy (TIR‐FM). Here, we first demonstrate that low levels of expression of a green fluorescent protein (GFP) conjugate of the focal adhesion protein, vinculin, results in clusters of fluorescent vinculin speckles on the ventral cell surface, which by immunofluorescence labelling of total vinculin correspond to sparse labelling of dense focal adhesion structures. This demonstrates that the FSM principle can be applied to study focal adhesions. We then use both GFP‐vinculin expression and microinjected fluorescently labelled purified actin to compare quantitatively the speckle signal in FSM images of focal adhesions and the actin cytoskeleton in living cells by TIR‐FM and wide‐field epifluorescence microscopy. We use quantitative FSM image analysis software to define two new parameters for analysing FSM signal features that we can extract automatically: speckle modulation and speckle detectability. Our analysis shows that TIR‐FSM affords major improvements in these parameters compared with wide‐field epifluorescence FSM. Finally, we find that use of a crippled eukaryotic expression promoter for driving low‐level GFP‐fusion protein expression is a useful tool for FSM imaging. When used in time‐lapse mode, TIR‐FSM of actin and GFP‐conjugated focal adhesion proteins will allow quantification of molecular dynamics within interesting macromolecular assemblies at the ventral surface of living cells.     

Effect of vibration condition and inter-particle frictions on the packing of uniform spheres

We present a numerical study of the packing of uniform spheres under three-dimensional vibration using the discrete element method (DEM), focusing on the effects of vibration condition (amplitude and frequency) and inter-particle frictions (sliding and rolling frictions). The results are analysed in terms of packing density, coordination number (CN), radial distribution function (RDF) and pore structure. It is shown that increasing either the vibration amplitude or frequency causes packing density to increase initially to a maximum and then decrease. Both vibration frequency and amplitude should be considered to characterize the effect of vibration process on packing structure. The sliding and rolling frictions between particles can decrease packing density since they dissipate energy, although the effect of rolling friction is less significant. In line with the change of packing density, microstructural properties such as CN, RDF and pore distribution also change: a looser packing often corresponds to smaller CN, less peaked RDF and larger but more widely distributed pores.     

储层压力与天然气分布关系——以鄂北塔巴庙地区上古生界储层为例

通过分析塔巴庙地区储层压力的分布特征，建立了研究区泥岩压实曲线，并对影响和控制该区储层压力的主要因素和机理进行了探讨，对“欠压实”剩余压力、生气增压、抬升引起的降压进行了定量计算。分析结果表明，晚三叠-早白垩世末“欠压实”作用和晚侏罗-早白垩世末烃源岩大量生烃作用使塔巴庙地区上古生界形成异常高压；晚白垩系构造抬升降压，使得现今储层为正常-低异常压力。同时证实了“欠压实”对天然气有压力封盖作用，天然气都分布在最大“欠压实”幅度以下的储层当中。烃源岩生气高峰为晚侏罗-早白垩世末，但天然气大规模运移是在晚白垩世，方向以沿过剩压力梯度降低较快的方向（太原-山西组至下石盒子组）垂向运移，通道主要为裂缝，运移的动力主要为异常高压。由于储层致密，聚集成藏能量有限，造成天然气充注不足、气水分异不好、含气饱和度低。     

Progress in the development of polymer cholesteric liquid crystal flakes for display applications

Polymer cholesteric liquid crystal (PCLC) flake technology is being developed as an alternative display technology for flexible, reflective particle displays. The motion of PCLC flakes suspended in a host fluid can be controlled with an electric field, creating a way to electrically control the flakes' ability to brightly reflect light that is circularly polarized. The PCLC flake/host fluid dispersion has been successfully microencapsulated both in a polymer matrix and in gelatin micro-capsules. Microencapsulation will not only expand the applications scope of the technology, but also may aid in addressing some potential problem areas that are inherent to many forms of particle display technology. A second important development in PCLC flake technology involves the manufacture of shaped flakes based on soft lithography techniques. The size and shape of a flake impact its reorientation, and uniformly shaped flakes respond in a similar manner. The unique reflective properties of PCLC flakes also provide possible applications in areas such as optics and photonics, switchable ‘smart windows’ or conformal coatings, and information displays such as ‘electronic paper.’
