The studies of continental deep subduction and ultrahigh-pressure metamorphism have not only promoted the development of solid earth science in China, but also provided an excellent opportunity to advance the plate tectonics theory. In view of the nature of subducted crust, two types of subduction and collision have been respectively recognized in nature. On one hand, the crustal subduction occurs due to underflow of either oceanic crust (Pacific type) or continental crust (Alpine type). On the other hand, the continental collision proceeds by arc-continent collision (Himalaya-Tibet type) or continent-continent collision (Dabie-Sulu type). The key issues in the future study of continental dynamics are the chemical changes and differential exhumation in continental deep subduction zones, and the temporal-spatial transition from oceanic subduction to continental subduction.

某涡桨发动机滑油压力异常故障的试验分析

工程与试验 2018年第1期58卷 46-49,76页

作者：张永飞李超杨建丰刘凯祥中国航发湖南动力机械研究所湖南株洲412002

作者： DENG yongfei GAO Guoping zhang Yu CHEN Changsheng College of Marine Sciences Shanghai Ocean University Shanghai 201306 China College of Ocean Science and Engineering Shanghai Maritime University Shanghai 201306 China

A high-resolution Arctic Ocean-Finite Volume Community Ocean Model(AO-FVCOM) and observational current data from 14 mooring stations in Bering Strait and surrounding regions between 1990 and 2015 were used to study the seasonal and interannual variability of Bering Strait throughflow(BST). AO-FVCOM represented the BST with a climatological northward flux of 1.06 Sv, which was close to the observational mean of 0.94 ± 0.26 Sv. From the model results, the strongest volume flux was in summer, approximately 45% larger than that in winter. Interannual variability of BST was also indicated in the model results, and the maximum and minimum annual mean transports are in 2007 and 2012, respectively. AO-FVCOM showed larger differences from the observations in 2000, 2002, and 2015 than in other years, which may be related to the limitation of atmospheric forcing for the model. According to the driving mechanisms of BST, sea level difference(SLD) across the strait dominates the northward volume transport, and local wind is also important in forcing the seasonal variability of the BST and SLD patterns to change the BST indirectly.

The Madang Cenozoic sodic alkaline basalt occurred in the eastern margin of the Tibetan Plateau, where is a key tectonic transform region of Tibet, North China, and Yangtze blocks. The basalts are characterized by the variation in SiO2=42%―51%, Na2O/K2O>4, belonging to the sodic alkaline basalt series. The rocks are enriched in Ba, Th, Nb, Ta, relative to a slight depletion in K, Rb in the trace and rare earth element (REE) spider diagrams that are similar to the typical oceanic island alkaline basalt. The Sr-Nd-Pb isotopic compositions suggest that they are derived from a mixed mantle reservoir. The western Qinling-Songpan tectonic region was controlled by Tibet, North China and Yangtze blocks since Cenozoic, therefore, the region was in the stage of the substance converge from the mantle to upper crust, producing a mixed mantle reservoir in the studied area. The Madang basalts occurred in the specific tectonic background, they result from partial melting of a mixed asthenospheric mantle reservoir in the western Qinling-Songpan tectonic node.

针对现有分层注水井分注层段确定方法实用性较差的技术问题,开展了分注层段优化方法研究。应用生产动态大数据分析方法,确定出与分注段划分密切相关的10项地质参数;利用归一化、变权及矩阵等数学变换方法,建立了分注层段计算数学模型;结合油藏数值模拟技术和矿场动态监测拟合技术,形成了以10项地质参数为基础,以提高油层动用程度为目标的合理分注政策界限优化方法。实例计算表明,该方法所需参数容易获得,计算过程简单,克服了现有方法仅考虑静态地质参数适用性差,或需要建立复杂地质模型开展数值模拟的繁琐计算过程等,实现了利用注入端、采出端及井网间三类地质参数辅以简单数学计算即可确定分注方案的新方法。以井组gXⅡ为例,应用该方法优化并现场实施,油层动用程度提高了15.7个百分点、产油量增加了23.4 t/d、综合含水率下降了1.16个百分点,验证了分注井段优化新方法的实用价值。
