井架

Derrick discourages Wendy from making one-off solutions because doing so causes efficiency to go down.

井架劝阻温迪作出一次过的解决方案，因为这样做的原因效率下降。

The drilling crew is responsible to skid the derrick back to the drilling position.

钻井班移动井架到工作位置。

When they think that the rocks in a certain place may contain oil, a metal tower called a derrick is built.

当认为 某处的岩石可能含油时，就在那里树立起一个叫做井架的金属钻塔。

The stress in tower type of derrick is smaller than the other types of derricks under the combined action of compressive and torsional loads.

与仅受压载荷相比，井架承受压扭联合载荷时，弦杆应力稍有增加，而非弦杆应力有较大的增加。

INTERNALLY DISPLACED \ 流离失所 A worker climbed up a pole to get to a drill as a crew dug a hole for a new clean water well in Chota Lahore relief camp in Swabi, Pakistan, Tuesday.

周二在巴基斯坦斯瓦比的寇塔拉合尔难民营，一名工人爬上钻井架，以寻找新的干净水源。

Derrick parameter changes at many complicated situations were observed by computer, which was impossible in field or laboratory calculation results showed stress of derrick was smaller when bearing weight at the lower part of the body than that at the upper part, and the maximum stress distributed in positive and back crossbeams of necking site.

通过计算机实显示现场和实验室都无法实现的多种复杂情况下井架参数变化过程。

This thesis presents a method of double nonlinear analysis to study the mechanical behavior of derricks steel structures.

本文应用双重非线性有限元方法研究井架结构的力学行为。

According to the analysis, the nonlinear effects are mainly on the stiffness of downhole derricks steel structure.

本文研究了井架结构的极限承载力问题。

Steel derricks rose to meet our eyes as we drew nearer to the oil fields.

我们快到油田时看到了矗立的井架。

Length method. Results show that in order to determine the ultimate load capacity of the derricks, both geometrical and material nonlinearities must be considered.

计算结果表明，采用几何和材料双重非线性的分析方法能准确评估井架的极限承载力。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
