spudding

It is bring forward three conditions that are before spudding , during process of drilling , and after the bottom formed are simulated more truly by three time steps . A finite element analyses program is developed .

提出用3个时间步较真实地模拟了开钻前、钻进过程中和井底形成后3种状态下的井底应力场，编写了有限元分析程序。

As soon as everything was ready , they started spudding in .

当一切就绪后，他们立刻着手打井。

The Drilling and Completion Techniques and Treatments for Troubles While the Fourth Spudding in Sha 88 Well

沙88井四开井段钻井完井技术及复杂情况的处理

Tired of digging potatoes , and spudding up docks ;

对掘土豆和除草早已经充满厌倦的我们；

The paper describes the structure , working principle and feature parameter of all spudding type , pressure type , shooting type and suction type subsea samplers .

介绍了多种型号的冲击打入式和振动式海底取样器的结构、工作原理和性能参数；

The complex formations were drilled during the fourth spudding in Sha 84 Well , which resulted in long drilling cycle , multiple trips , and therefore casing abrasion .

沙84井四开井段钻遇复杂地层，钻井周期长，多次起下钻，造成技术套管磨损。

The drift diameter was enlarged by milling , and a 177 . 8mm casing was connected back to the surface , which sealed off the damaged casing and assured the successful fifth spudding .

经过磨铣，建立了通径，通过回接一段φ177.8mm套管，封隔了技术套管破损井段，保证了五开钻井作业的顺利完成。
