In the context of complex tectonic evolution， due to the control of tectonic compression stress and faults on tectonic fractures， the formation and development of tectonic fractures in the T3x2tight reservoirs present significant variations across different tectonic segments in the Western Sichuan Foreland Basin. We clarified the control of differential tectonic evolution on the formation and development of tectonic fractures in different tectonic segments through field-based observations， core samples， image logging， as well as fluid inclusion petrography and temperature determinations of fracture-filling materials， combined with 2D balanced cross-section restoration. The study area primarily manifests two types of tectonic fractures in the tight reservoirs: orogen-related fractures （regional fractures） and fault-related fractures. The orientations of these fractures are predominantly E-W， nearly N-S， NE， and NW. Specifically， the northern segment area only shows the development of regional fractures， while the southern and middle segments exhibit the development of both regional and tectonic fractures. There are three phases of tectonic fractures in different tectonic segments， and their formation times are relatively consistent. The Mesozoic tectonic events had a significant impact on the northern and central segments， with the amount of tectonic shortening and the rate of stratigraphic shortening gradually decreasing from the northeast to the southwest. The compressional stress resulting from tectonic compression also decreases from the northeast to the southwest. As a result， the development of first-phase and second-phase tectonic shear fractures is more pronounced in the northern and middle segments compared to the southern segment. Under the significant control of faults， the development of N-S- and NE-oriented fault-related fractures is more pronounced in the southern segment， while the development of NE-oriented fault-related fractures is relatively higher

在数字资本主义时代,数字技术与资本全面联姻,重塑了人类的生活方式和交往空间,并造成了生命主体间的交往异化,这种异化表现为交往主体在数字虚体遮蔽下丧失真实性、交往行为在数字资本操纵下渐趋利益化、交往关系在数字平台互动中产生疏离感等多重面向。究其根源,数字技术与资本逻辑双重合谋对数字交往空间进行圈占,在数字平台的算法控制下,以及生命主体在数字技术的崇拜中造成主体迷失,共同导致数字资本主义时代交往异化的产生。而树立辩证数字资本观、以人本逻辑规训数字资本、形塑和谐有序的数字交往平台则成为重构数字资本主义时代交往异化的可能性方案。

Effect of alcohol solvents treated ZrO(OH)_2 hydrogel on properties of ZrO_2 and its catalytic performance in isosynthesis

引用

Journal of Natural Gas Chemistry 2012年第1期21卷 1-6页

作者： rongjun zhang Dehua He Innovative Catalysis Program Key Lab of Organic Optoelectronics and Molecular EngineeringDepartment of ChemistryTsinghua UniversityBeijing 100084China

A series of ZrO2 catalysts were prepared by treating ZrO（OH）2 hydrogel with different alcohol solvents （C2-C4 alcohols） and calcining under N2 flow at 773 K for 3 h. The obtained ZrO2 catalysts were systematically characterized by the methods of N2 adsorption-desorption, powder X-ray diffraction, NH3 temperature-programmed desorption, and CO2 temperature-programmed desorption. The catalytic performance of each catalyst was evaluated in the selective synthesis of iso-C4 （isobutene and isobutane） and light olefins （C2-C4） from CO hydrogenation. The specific surface area increased for the ZrO2 catalysts obtained by treating ZrO（OH）2 hydrogel with different alcohol solvents. The amounts of both acidic and basic sites on the catalyst surface increased obviously. The catalytic activity （CO conversion） of ZrO2 catalysts also increased after the treatment with different alcohol solvents. The nighest activity was obtained over the catalyst which was pretreated with isopropanol. However, alcohol solvent treatment retarded the transformation of ZrO2 crystal structure from tetragonal phase to monoclinic phase, and subsequently resulted in the decrease of monoclinic phase in ZrO2, which led to the decrease of olefin selectivity in corresponding hydrocarbon products （C2-C4/CH）.

絮凝调理和化学固化改性处理能改善高含水率淤泥初始不良工程特性,将废弃淤泥(浆)资源化利用为路堤填料对淤泥强度有一定要求。已有研究证实了絮凝-固化-真空预压联合法(VPFSCM)可以有效处理高含水率淤泥浆(含水率>300%),且处理后的淤泥强度满足路堤填料需求。通过室内模型箱试验探索VP-FSCM工艺处理废弃淤泥(含水率约为150%~300%)的可行性和高效性;优化VP-FSCM工艺在处理淤泥中的外加剂配方(类型和掺量等)。试验结果表明:VPFSCM处理废弃淤泥后土体28 d不排水抗剪强度为絮凝-固化法(FSCM)处理废弃淤泥后的2.76倍,证实了VP-FSCM处理废弃淤泥的高效、可行性。沉降脱水和力学等特性分析结果表明,VPFSCM工艺处理废弃淤泥的最佳外加剂种类为水泥(OPC)、高炉矿渣(GGBS)、生石灰(CaO)和聚丙烯酰胺(PAM),且最优掺量分别为5.0%、5.0%、1.5%、0.12%;在最佳外加剂类型和掺量条件下,真空压力越高,处理后的废弃淤泥不排水抗剪强度越高,养护后含水率越低。
