The Ordos Basin in the western part of the North China Craton is commonly believed to be a multi-controlled oil- bearing basin. It is bounded by the Xing＇an--Mongolian Orogen to the north, the Qingling Orogen to the south, the Lüliang mountain to the east and the Helanshan--Liupanshan mountain belt to the west. The interpretation of geophysical data reveals a latitudinal （38°） fault belt in the centre of the Ordos Basin, which controls the hydrocarbon generation, migration and accumulation in the basin. This study attempts to investigate this belt from outcrops and indicates a structurally controlled system of migration fairway within the fault belt.

随钻跟管桩(简称DPC桩)是一种钻孔-沉桩-排土同步进行的无泥浆排放的节能环保型大直径新型非挤土PHC管桩。为探究随钻跟管桩在南宁盆地特殊地层的适应性及承载特性,开展了现场原位试验、数值模拟分析,分析了这种新桩型的承载性能优势、桩侧摩阻力分布特征、荷载传递特性。得出如下结论:原位静载试验中,各试验桩荷载-沉降曲线呈缓变型,且承载性能均满足设计要求,桩身回弹率较高,各试验桩仍具有较大的承载潜力;桩身轴力沿桩身近似呈线性递减,桩端荷载约占桩顶荷载的20%~30%,桩侧摩阻力分担了70%~80%的桩顶荷载;桩侧摩阻力沿桩身深度分布均表现出了两头小、中间大的规律,随着荷载增加,桩侧摩阻力逐渐下移。可见,该桩型在南宁盆地特殊地层具有良好的适应性。

为了研究静压随钻跟管桩在南宁盆地特殊地层的适应性及单桩承载特性,对现场4根直径800mm的静压随钻跟管桩进行静载及低应变反射波法试验。研究结果表明:各地层中的试验桩承载力均能满足设计要求且均属于Ⅰ类桩,桩身回弹率较高,说明各试验桩仍具有较大的承载潜力;未进行破坏性试验时各地层中单桩承载力综合增强系数均大于1.00,以经验公式确定静压随钻跟管桩的单桩竖向承载力时应乘以相应的增强系数。基于以上研究,将静压随钻跟管桩工艺应用于实际工程,经验收检测表明,各项目受检基桩的桩身质量完好,承载力均满足设计要求,且仍具有一定的承载力富余量,良好的实际工程应用效果表明该工艺具有良好的适用性以及较高的推广使用价值。

Continuous silicon carbide fiber reinforced silicon carbide matrix(SiC_f/SiC) composites are attractive candidate materials for aerospace engine system and nuclear reactor system. In this paper, SiC_f/SiC composites were fabricated by polymer infiltration and pyrolysis(PIP) process using KD-S fiber as the reinforcement and the LPVCS as the precursor, while the BN interface layer was introduced by chemical vapor deposition(CVD) process using borazine as the single precursor. The effect of the BN interface layer on the structure and properties of the SiC_f/SiC composites was comprehensively investigated. The results showed that the BN interface layer significantly improved the mechanical properties of the KD-S SiC_f/SiC composites. The flexure strength and fracture toughness of the KD-S SiC_f/SiC composites were evidently improved from 314±44.8 to 818±39.6 MPa and 8.6± 0.5 to 23.0±2.2 MPa·m^(1/2), respectively. The observation of TEM analysis displayed a turbostratic structure of the CVD-BN interface layer that facilitated the improvement of the fracture toughness of the SiC_f/SiC composites. The thermal conductivity of KD-S SiC_f/SiC composites with BN interface layer was lower than that of KD-S SiC_f/SiC composites without BN interface layer, which could be attributed to the relative low thermal conductivity of BN interface layer with low crystallinity.

The Chang-63 reservoir in the Huaqing area has widely developed tight sandstone ＂thick sand layers, but not reservoirs characterized by rich in oil＂, and it is thus necessary to further study its oil and gas enrichment law. This study builds porosity and fracture development and evolution models in different deposition environments, through core observation, casting thin section, SEM, porosity and permeability analysis, burial history analysis, and ＂four-property-relationships＂ analysis.
