摘要
对套管柱的受力及强度的计算与分析,得出设计、校核套管强度不仅要考虑抗拉、抗挤、抗崩,同时还应重视孔壁完整及高速回转钻杆等附加外载对套管强度的影响,并提出了具体护管措施.
Through an analysis of the bearing force of a casing column and a calculation of its strength, itis to be noted that in designing and testing the strength of casing pipe, its tensile, compressive andbreaking strengths should be taken into consideration as a whole. In addition, to the completeness ofhole-wall and the effect of the additional external load due to the high speed rotating drilling rod tothe strength of the casing pipe, much attention must be also devoted. Some specific measures for plpeprotection are put forward.
