1) high WOB
大钻压
1.
Under the condition of poor effect of surmounting "statics with pitch-resistant",domestic scholar have made new concept —deviation control with high WOB.
大钻压动力防斜技术增加钻压引起钻柱屈曲,保特钻柱涡动,有井斜时使钻柱产生周期性变化的轴向附加力,无井斜时轴向附加力消失,克服了传统防斜技术中吊打的缺点,提高了钻井速度,达到了解放钻压的目的。
2) maximum allowable weight on bit
大允许钻压
3) drilling with high water level and large elevation angle
高水压大仰角钻孔
1.
Trying on drilling with high water level and large elevation angle;
高水压大仰角钻孔施工的尝试
5) bit weight
钻压
1.
Most conventional anti-deviation devices have inherent limitations, and their anti-deviation effects are greatly affected by drilling parameters such as bit weight and rotary speed.
FG型防斜工具的显著特点是其防斜效果受钻压、转速等钻井参数影响较小,钻头侧向力大小基本不随钻压改变,在旋转过程中钻头侧向力方向可以不断变化。
2.
It is difficult to process signals of near bit weight on bit(WOB) and torque due to weak effective signal and strong noise.
针对井下近钻头钻压、扭矩测量中由于被检测信号微弱并伴有强噪声信号,造成信号处理困难的问题,利用锁相放大技术来处理微弱信号,以锁相放大器为核心,设计了井下近钻头钻压、扭矩测量中的微弱信号调理电路,在电路中通过采用平衡调制解调芯片AD630,把微弱的窄带信号从干扰噪声中分离出来。
6) bit pressure
钻压
1.
Numerous investigations have been conducted aiming at the problems of the low penetration rate and easy deviation during drilling in deep and complicated formations, the high bit pressure during drilling large-diameter holes or horizontal wells, and the high drilling costs, etc.
针对目前深部、复杂地层钻速低和易产生井斜、大直径井眼和水平井施加钻压困难、钻井成本高等问题进行了大量的调研。
