柳沟庄—窟窿山油藏储集层裂缝类型及特征

根据岩心描述、薄片观察、X－CT扫描以及钻井、测井等资料，研究了酒西盆地青西坳陷柳沟庄－窟窿山油藏裂缝性储集层的类型及特征，分析了控制裂缝发育的地质因素及裂缝对油气的控制作用，认为储集层裂缝有3种基本类型，即构造裂缝、构造熔蚀缝和饼状破裂，主要受构造应力场及构造位置等因素的控制。根据裂缝形态、充填特征及其相互关系，裂缝的形成主要有3个期次，其中喜马拉雅运动晚期形成的第三期理解缝对油气运移和聚集最有效。研究结果表明，裂缝是柳沟庄－窟窿山油藏主要的储集空间和控制油气富集的因素。

In situ formation of multi scale reinforcing phases to improve performance of Al2O3-SiC C castables

In order to improve the physical properties and slag corrosion resistance of refractory materials for hot metal pretreatment, different contents of composite metal powders (CMP) were introduced into Al2O3-SiC-C refractory castables. The effect of CMP on the microstructure, physical properties and slag corrosion resistance of Al2O3-SiC-C refractory castables were studied. The results show that the multi scale reinforcing phases including flake crystals, rod shaped fibers, filamentous fibers and whiskers are in situ formed in the samples with addition of CMP, which result to the improvement of the cold modulus of rupture and cold crushing strength. When the addition of CMP is 6 wt.%, the high temperature modulus of rupture increases by 231%, the thermal shock resistance increases by 77% after thermal shock by water cooling 5 times and the percentage of the slag resistant area reduces by 37.2%.

Structural transformation of FePt nanocomposite films during annealing and its effects on magnetic properties

Fe100-xPtx(x=30at.%-60at.% ) nanocomposite films were deposited on natural-oxidized Si(100) substrates by magnetron sputtering. The as-deposited films were annealed between 373 and 1073 K. In situ X-ray diffraction shows that the FePt nanocomposite films undergo a phase transformation from a disordered FCC phase to an ordered L10 phase between 673 and 773 K. The coercivity is 306 kA·m-1 whiles the average grain sizes is about 10 nm in the optimized FePt alloy film sample annealed at 673K. The adjustable coercivity and fine grain size suggest that this FePt nanocomposites system is suitable as recording media at extremely high areal density.
