﻿在高性能钻井应用中， In high-performance drilling applications,
钻井效率才是关键。 drilling efficiency is the name of the game.
使用传统的PDC钻头，能量通常以破坏性, With conventional PDC bits, energy is often wasted in the form of destructive,
横向和扭转振动的形式浪费， lateral and torsional vibration,
损害机械钻速，定向控制和钻井工具，甚至损害井眼。 hurting your ROP, directional control and potentially your tools and even your well.
无论是由钻头还是钻柱引起， Whether initiated by the bit or drill string,
钻头的振动都会迅速损坏钻头切刀， the vibration at the bit can quickly cause damage to the cutters,
使钻头变钝并导致起下钻困难。 dulling a bit and causing a trip.
作用在钻头切刀上的波动侧向力， Fluctuating lateral forces act on the cutters,
会产生锯齿状的切削路径和井底形状， generating jagged cutting path and bottomhole pattern,
对破碎地层的切刀造成影响，甚至造成损坏。 impacting and damaging the cutters against the formation.
反作用力是一项Ulterra正在申请专利的技术， Counterforce, a patent-pending technology from Ulterra,
它能够使切刀定向，从而解决该问题。 orients the cutters to address this problem head-on.
将切刀倾斜，利用来自地层的反作用力 The cutters are tilted to use reactive force from the formation
抵消钻柱的侧向力。 to counter the lateral forces from the drill string.
反作用力切割结构使切刀协同工作， The counterforce cutting structure also aligns cutters to work together,
利用这种能量更有效地破坏岩石。 harnessing that energy to more efficiently fail the rock.
其结果是能够产生更平滑，更有效的钻井作业， The result, much smoother more efficient drilling,
钻头更锋利，钻进速度更快，应用时间更长。 and a bit that stays sharper and drilling faster, longer.
反作用力的好处是允许使用更具破坏性的钻头设计， The benefits of counterforce allow more aggressive bit designs to be used,
更进一步的原因，如反作用力，从竞争中脱颖而出。？？ even further reason like counterforces out drills the competition.
事实上，在北美各地的应用中， In fact, over a million feet of test runs with counterforce in applications
超过100万英尺的反作用力测试证实，Ulterra的新技术 across North America confirm that Ulterra’s new technology
在垂直,切线,曲线和横向截面上 also vastly improves directional stability
都有非常平滑的刀面控制 with remarkably smooth tool face controls
极大地提高了方向稳定性。 in vertical, tangent, curved and lateral sections.
每一次运行都经过现场验证，始终如一、安全可靠。 Field-proven, consistent and reliable when every run counts.
这就是反作用力。 That's counterforce.
