Discussion on marine source rocks thermal evolvement patterns in the Tarim Basin and Sichuan Basin,west China

Taking marine source rocks of lower Paleozoic in the Tarim Basin and Paleozoic ones in the Sichuan Basin as examples, their sedimentation process could be classified into four styles: continuous subsidence with deep sedimentation in early stage, continuous subsidence with deep sedimentation in later stage, that deeply buried-uplift-shallowly buried, and that shallowly buried-uplift-deeply buried. Unlike that in East China, the marine source rocks evolvement patterns did not accord with sedimentation styles one by one in superimposed basins in west China. Taking local geothermal field into account, four types of source rock evolvement patterns were built: that evolved fast in early stage, evolved fast in middle stage, evolved continuously and evolved in multistage. Among them, the 1st pattern contributed little to the present industrial oil pools directly, but paleo-oil reservoirs and gases cracked from crude oils were main exploration targets. Although some gases were found in the 2nd pattern, the scale was not big enough. For the 3rd and 4th patterns, the hydrocarbon potential depended on organic matters maturity in early stage. For relatively low mature rocks, it was possible to generate some oils in later stage; otherwise the main products were gases. Paleo-oil reservoirs remained fairly well in the Sichuan Basin, and most source rocks underwent kerogen-oil-gas processes, which was useful reference to gas exploration in the Tarim Basin.

可伐合金在模拟现场N2/H2O二元气氛下的氧化行为

采用称重法、X射线衍射(XRD)和扫描电子显微镜(SEM)研究了可伐合金(Fe-29Ni-17Co)在模拟现场N2/H2O二元气氛下的氧化行为. 可伐合金在1000℃不同露点的N2中氧化的增重曲线表明其氧化动力学遵循抛物线规律. XRD和SEM分析显示了在上述条件下表面氧化物的组成和形貌. 通过热力学计算说明可伐合金在现场的N2/H2O二元气氛下氧化时,外界空气会渗入炉内增加氧分压,导致表面氧化物中不可避免存在α-Fe2O3. 在露点温度较高和氧化时间较长时,生成α-Fe2O3的数量会超过Fe3O4.     

Development of an Accurate Urban Modeling System Using CAD/GIS Data for Atmosphere Environmental Simulation

This paper presents an urban modeling system using CAD/GIS data for atmosphere environmental simulation, such as wind flow and contaminant spread in urban area. The CAD data is used for the shape modeling for the high-storied buildings and civil structures with complicated shape since the data for that is not included in the 3D-GIS data accurately. The unstructured mesh based on the tetrahedron element is employed in order to express the urban structures with complicated shape accurately. It is difficult to understand the quality of shape model and mesh by the conventional visualization technique. In this paper, the stereoscopic visualization using virtual reality (VR) technology is employed for the verification of the quality of shape model and mesh. The present system is applied to the atmosphere environmental simulation in urban area and is shown to be an useful planning and design tool to investigate the atmosphere environmental problem.
