摘要
根据柴达木盆地砾岩地层特点,分析钻井中钻柱损伤机理,论述在砾岩中旋转钻柱的纵向振动、剪切应力变化提出6项现场预防措施。
The mechanism of drilling string damage is analyzed according to the properties of conglomerate formation in Caidamu basin. Variation longitudinal vibration and shear stress of a rotating drilling string in conglomerate formation are discussed and six preventive measures are put forward.
