摘要

摘要: 尾管悬挂固井作业过程中，钻杆受到多种载荷联合作用产生轴向变形；若注水泥施工步骤前的钻杆上提距离过短，会导致钻杆和尾管悬挂器在后续作业时重新扣合，使得起钻时悬挂器无法顺利脱手造成卡钻。通过对直井尾管固井施工过程中钻杆受载情况的分析，并基于钻杆接头与钻杆本体存在结构差异这一特点，提出了一种综合考虑结构场、温度场、压力场等因素的钻杆接头最大伸长量工程计算模型。运用该模型可以对尾管固井过程中钻杆的伸长量进行更加准确的分析计算，尽量减少卡钻事故。通过分析得知，静止状态下钻杆的轴向伸长量是最大的；对钻杆接头伸长量影响最大的因素是温度场，影响最小的因素是压力场，且温度对钻杆接头的影响要比对同尺寸的管柱的影响略小。

Abstract: In the process of liner hanging cementing, the drill pipe will have axial deformation due to the joint effect of multi-loading. Before the cementing construction procedure, if the drill pipe lifting distance is too short, the drill pipe and the liner hanger may close again in the follow-up actions, thus blocking the drilling tool due to the unsuccessful releasing of the hanger when pulling the drill tool out of the hole. By analyzing the drill pipe loading conditions in the liner cementing process for plumb shaft, based on the features that the drill adapter is different from the drill pipe structure, this paper puts forward an engineering calculation model for the maximum elongation of drill adapter with comprehensive consideration of factors including structure field, temperature field, pressure field and so on. With this model, the drill pipe elongation in liner cementing process can be calculated precisely to minimize the sticking of tool. The analysis results show that the drill pipe has a maximum axial elongation in stationary state and the temperature field has largest influence on drill adapter elongation, while the pressure field has the smallest influence. The temperature has smaller influence on drill adapter than on pipe column of the same size.
