摘要
钻井作业过程中,当钻柱在井眼内运动时,由于钻压及井下的情况的限制,钻柱在偏心的情况下旋转对环空压耗的影响很大,文中对于钻柱偏心和钻柱旋转的情况作了实例化的分析,以利于我们了解当钻柱在偏心和旋转的情况下运动时井下压力的变化情况。
during drilling operation,when drilling string rotating in the borehole,because of weight on bit and downhole limitation,drilling string rotating in eccentric can make a great influence on annular pressure loss,this text made example to analysis the eccentricity of drillstring and rotating,in order to help us understand when drillstring eccenter and rotating in the well how downhole pressure change.
