尽管对钻具在孔内卡夹的问题有大量的研究,但有关的许多问题是有争议的。其中包括钻杆与孔壁相互作用的第一类卡夹的问题。根据钻进实践和模型试验确定,使钻杆从孔壁移动和脱离所需的力是不断的增加的。卡夹力随时间的增长具有衰减的性质。本文将阐明上述现象和建立卡夹过程的计算模 Although there is a lot of research on the problem of drilling tools stuck in holes, many problems are controversial. This includes the problem of the first type of clip that interacts with the hole wall. According to drilling practice and model tests, the force required to move and disengage the drill pipe from the hole wall is continuously increasing. The clamping force has an attenuating nature over time. This article will clarify the above phenomena and the computational modeling of the establishment of the clip process.
