摘要
对水平井眼中钻柱所能承受的临界载荷进行了分析计算,推导出了水平井眼中钻柱临界压力的计算公式。研究表明,水平井眼中钻柱所能承受的临界载荷和所使用钻杆的单根长度有密切关系。钻杆的单根长度越长,钻柱所能承受的临界载荷越小。
The critical compressive force of drill stem compressed in horizontal well is analyzed and calculated in this paper,and the calculation formula of critical compressive force of drill stem in horizontal well is deduced. The research indicated that the critical compressive force of drill stem in horizontal well is closely related with the length of single drill pipe in use. The longer the single drill pipe,the lesser the critical compressive force of drill stem.
