查询词典 spudding

Extends PDC life through fine weight transfer; no spudding

平稳的传递钻压，有效的延长PDC钻头的使用寿命，不会产生顿钻现象。

Based on large amounts of geological and engineering appraisal, application test of nitrogen drilling technology is conducted in the producing interval of 4652.26~4775.56m during the fourth spudding in DY1 well.

试验表明，在深井段采用氮气钻井技术可大幅度提高钻井速度，该层段平均机械钻速达8.36m/h，与邻井相比提高8~9倍，在提高钻速的同时还直观有效地发现了一个裂缝性气层该技术在深探井中的成功应用加快了气体钻井技术向深层推广的步伐，对同类地区的钻井具有较高借鉴意义。

Therefore, the fourth spudding is stopped as it reaches to the depth of 5004 m, cementing with 177.8 mm liners.

鉴于此种情况，现场决定四开钻至5004m中途完钻，下177.8mm尾管固井。

The paper articulates the drilling fluids techniques employed for drilling huge gravels, large gypsums in deep wells, long shales, high pressure brines under high bottomhole temperature in extreme deep wells. This paper also discusses how to determine mud density for the fourth spudding, how to optimize mud addi...

详细介绍了该井大井眼巨厚砾石层、深井段巨厚盐膏层、第三系大段泥岩井段、高压盐水层及超深井高温条件下的钻井液工艺技术并对四开钻井液密度的确定、钻井液处理剂的优选和五开井段钻井液粘切的要求进行了探讨。

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.

为了得到适合有限元分析的模型，我们必须经过如图2所示的简化步骤。
