简介:摘要:本文详细说明了某水池基坑开挖及支护施工过程,在充分考虑现场地质、水文及相邻构筑物的不利条件编制施工方案,较好的做到了施工安全与施工成本最佳控制,不失为中小型基坑开挖与支护施工的较好案例。
简介:基于井核心,薄节和FESEM的观察,把指示物,水库特征和S字4-Esx的页岩油丰富的控制因素与X光检查衍射,物理性质测试和geochemical相结合在Jiyang消沉的3页岩被详细说明分析。研究证明碳酸盐和泥土矿物质在页岩被统治。根据三角图表,TOC内容(2%和4%),碳酸盐和泥土矿物质,九张岩相被识别了。水库空间类型富于页岩,在哪个,把压成薄片的破裂,再结晶intracrystalline毛孔和器官的毛孔是高质量的水库空格。页岩油丰富被生产烃的潜力和水库能力主要决定。烃--生产能力被器官的地球化学指示物,为学习区域的特别TOC内容,和器官富人的页岩的厚度控制。水库能力被岩相,TOC内容和结构的活动主要影响。另外,页岩采油被页岩的fracability影响,它被岩相主要控制,结构的活动,形成压力,等等。页岩油水库评估应该集中于TOC内容,器官富人的页岩的厚度,岩相和结构的因素。

简介:在一座水库估计沉积免职的数量的一个传统的方法简单地基于在在不同时间做的举起大小的变化。在现在的学习,一个地文学的土壤侵蚀免职(PSED)模型被用于Tseng皮脂腺囊瘤水库分水岭计算分泌物和沉积集中进水库,和免职体积。PSED模型用三个暴风雨事件然后与在水库分水岭在水文学车站记录的历史性的数据相比被验证,它显示出在流动分泌物的模仿并且记录的价值之间的靠近的同意进水库和相应沉积收益。数字模拟也从1996~2001为所有降雨事件被进行在水库估计年度沉积免职体积。同样,模仿的结果与从剖面图举起测量获得了那相比。一些测量数据点有大无常或是可疑的,这被发现。相反,模型结果并且使模型变为可信的测量数据。因此,不管为流动的评价,进水库的分泌物由一个单个降雨事件,沉积收益,或沉积免职导致了,PSED模型成功地表明了它的能力。
