设计载荷
相关语句
  design load
    But because the measured points can only be set at the limited danger positions of derrick at loading test and the tested load is greatly lower than the design load, it is difficult to get the comprehensive and logical evaluation result.
    这种方法只能对有限的危险部位进行布置测点,而且试验载荷也大大低于设计载荷,因此很难取得全面、合理的评价结果。

    On the basis of investigations on the design, fabrications and applications of the inner floating roofs in China, this paper mentions the following points which need attention in design:①Determination of design load;
    在调查国内设计、制造及使用内浮顶情况的基础上,结合对国内外有关设计规范的理解,提出了在设计中应注意的问题:①设计载荷的确定。

    Test and analysis on failure of J55 type tubing string of 27/8in was made. Calculation and analysis show that mechanism performance and chemistry element meet design need and load on tubing string oversteps design load. It also shows screw thread failure is main reason.
    对某采油厂油井作业中的27/8in不加厚J55型油管失效进行了试验和分析,通过强度计算以及分析可知,油管的机械性能、化学成分满足要求,失效主要原因是油管悬挂载荷超出设计载荷且螺纹扣在开始旋合时就已经损坏,造成失效破坏。

  design load
A design is performed for the hyperbolic cooling tower (Grand Gulf cooling tower) to check the design strength under a consistent design load; therefore, to verify the adequacy of the design algorithm developed.
      
Based on these concepts, the following procedure for establishing case depth is suggested: 1) From design load and gear geometry data, compute the applied shear stress gradient at the most severe location along the path of contact.
      
A number of panels were then removed one by one and the hull was retested to the design load after each panel had been removed.
      
After nine panels had been removed, from all the different areas of the hull, it could still carry the design load, although with considerable nonreversible deformations of the hull girder.
      
The hull was eventually loaded to final failure, which occurred at 25% above the design load.

Inner floating roof tanks for product oil storage see a rapid development for the purpose of minimizing the product loss due to volatilization. Especially, fabricated inner floating roofs are well received due to the fact that they need no welding and all their parts are accessable through the manhole in the tank.

Inner floating roof tanks for product oil storage see a rapid development for the purpose of minimizing the product loss due to volatilization. Especially, fabricated inner floating roofs are well received due to the fact that they need no welding and all their parts are accessable through the manhole in the tank. On the basis of investigations on the design, fabrications and applications of the inner floating roofs in China, this paper mentions the following points which need attention in design:①Determination of design load;the concentrated, active design load for floating roof shall not be less than 2268N, and the uniform, active design load for the support leg shall not be less than 610 Pa.②Determination of buoyancy of the floating roof:the buoyancy of floating roof is a critical parameter in design, because it has a direct influence on the safe operation of the roof;the buoyancy is generally designed as much as two times the roof's weight.③Determination of roof size:while roofs having a too small diameter will result in oil vapour effusion from the gap between tank wand and roof rim, an over sized roof will lead to strained roof migration.

为了降低成品油储罐油气挥发损失,内浮顶油罐被大量采用,而装配式内浮顶因其无需焊接,所有零部件都可以从人孔送入,受到用户的欢迎。在调查国内设计、制造及使用内浮顶情况的基础上,结合对国内外有关设计规范的理解,提出了在设计中应注意的问题:①设计载荷的确定。浮顶设计集中活载荷不应小于2268N;而支柱设计均布活载荷不应于小610Pa。②浮顶浮力大小的确定。浮顶浮力的大小是浮顶设计极为重要的参数,它直接影响到浮顶的安全运行,一般按浮顶重量的2倍设计。③浮顶直径大小的确定。浮顶直径过小,会使蒸发的油气从罐壁与浮顶的间隙中溢出;浮顶直径过大,会使浮顶偏移量受到一定的限制。

Casing failure is increasing rapidly in recent years. Some wells,for instance, were found the casing damaged only a year or even a month after completion.It has caused great losses to oilfield's production. Those causes of casing failure are: 1. unreasonable design of casing string(especially in salt bed and mudstone (shale) formation); 2. unreasonable water injection; 3. casing Perforation; 4.corrosion; 5. sand problems, cementing quality and casing defect.

近年来,我国油田套管损坏速度呈直线上升趋势,有的井不足1年时间,有的井刚完井1个月套管就坏了,给原油生产带来重大损失。套管损坏,一是套管柱设计不合理,特别是在盐岩、泥(页)岩地层,设计载荷偏小;二是不合理的注水,加速了套管的损坏;三是套管柱强度设计本来就不富余,射孔给套管带来一定的损害,加速了套管损坏;四是套管的外腐蚀使套管穿孔造成内腐蚀,腐蚀使套管更易损坏;五是油层出砂、固井质量、套管缺陷等使套管损坏。造成套管损坏的因素很多,具体到每口井必然有一些主要因素,找到主要因素才好采取防范措施。
