富春江大坝船闸变形异常成因解析

监测资料表明,富春江左3闸墙段的上下游方向变位经常产生突变.通过定性和定量分析,对左3闸墙上下游方向变位异常进行了解析,发现主要是由于下游水位的日变化,以及每段闸墙结构状况不同和测点所处位置差异引起的,其上下游方向变位属于正常情况.     

欧元区内在矛盾与东扩前景

一引言当前,欧洲主权债务危机已经引起全世界的关注,其中债务危机最为严重的希腊,为了得到欧盟的援助,正在采取财政紧缩措施,不仅引起国内民众的极大不满,甚至在理论上存在退出欧元区的可能。主权债务危机说明最优货币区理论并非完美,加入欧元区并非只有收益,没有成本,这也更容易理解为什么英国、

Numerical simulation of cementing displacement interface stability of extended reach wells

The well cementing is important during the extended reach well drilling and the completion, whereas the displacement efficiency and the interface stability are important to guarantee the success of the cementing. In this paper, the interface stability of the cement slurry is simulated using the computational fluid dynamics software. The calculation results indicate that during the displacement, the length of the displacement interface increases with the increase of the deviation angle. The larger the eccentricity, the more significant the velocity difference, along with a longer displacement interface length, a less stable interface, and a lower displacement efficiency. Therefore, to guarantee the cementing quality and maintain a high displacement efficiency, the eccentricity should be controlled within 0.5. Application of a casing centralizer will dramatically improve the interface stability, decrease the dilution zone length of the interface and thus, is beneficial to the slurry cementing and displacement. The simulations are verified with an average absolute deviation less than 3.76% and the 45? helix angle of the rigid centralizer is recommended. Combining the data of an extended reach well on-site, methods are proposed for improving the displacement efficiency and the interface stability during the well cementing and displacement with complex boreholes. These numerical methods can be used to provide some theoretical guidance for designing the cementing of an extended reach well.
