井架

Using derrick simulation analysis 2000 system, 80/29 oil derrick model was established.

应用井架仿真2000软件系统建立了80／29采油井架模型，进而利用仿真系统对其进行静力、动力特性和稳定性分析。

Recently, with the application of finite element method in engineering mechanics, it is necessary and possible to study the welding procedure of domestic oil derrick materials, for the purpose of more appropriate procedure and to improve the welding quality and productivity of oil derrick.

近年来，随着计算机辅助设计在工程中的应用，有可能也有必要对国内井架材料的焊接工艺进行进一步的研究，制定合理的焊接工艺，提高井架焊接质量。

During the manufacture of oil derrick, such factors as welding defects, deforming and cold crack have key effect on the oil derrick quality.

在井架的制造过程中，焊接缺陷、焊接变形和焊接冷裂纹是影响井架质量的关键因素。

The stability analysis under pressure indicates that the whole stability is preferable, and can assure the normal work of the oil derrick.

对井架的模态分析表明，井架的固有频率与底盘发动机、绞车的工作频率不同，因此当绞车在不同转速下工作时，不会发生共振。

Those simulation analysis results can be used as scientific basis for derrick design staff to revise design and for detection staff to detect oil derrick in field.

仿真分析结果为井架设计人员修改设计方案、检测人员对在用采油井架现场检测提供科学依据。

In this paper, welding process parameters of oil derrick have been determined, and a suitable welding procedure have got by use of welding procedure qualifications. The paper pointed out the common defects in oil derrick welding, explained it, and gave preventive measures.

本课题通过焊接工艺评定，确定井架焊接的工艺参数，并指出了井架焊接中容易出现的焊接缺陷，分析了缺陷产生的原因，给出了预防措施。

The Air winch Operator must ensure the winch wire is moving freely in the derrick to avoid any damage to the steel structure especially the fingerboard and that the air tugger is secured when not in use.

气动绞车操作者要确认气动绞车钢丝绳和井架不干涉，以避免损伤井架的钢结构，特别是指梁。不使用气动绞车时，一定要固定安全。

The Driller and the Derrickman must be able to communicate at all times when the Derrickman is working on the derrick board.

当井架工在二层台工作时，司钻和井架工一定要能时刻保持联系。

In a typical trip out of the hole, the derrickman wears a special safety harness that enables him to lean out from the work platform to reach the drillpipe in the center of the derrick or mast, throw a line around the pipe and pull it back into its storage location until it is time to run the pipe back into the well.

在典型的起钻过程中，井架工系上特殊的安全带，这样能够使他从工作平台上倾斜去接近位于井架或者桅架中央的钻杆，扔一根绳子去缠绕钻杆，然后拉动钻杆到其存储的位置，直到再把这些钻杆下入到井眼时为止。

To evaluate correctly the load capacity of the derrick, a method of computer simulation test is proposed.

为了正确评定在用井架承载能力，提出了一种井架计算机模拟试验中等效处理计算机数值模型的方法。

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

在美国，慢性酒精中毒，肝炎是最常见的。
