若一段钻铤，每10m有一个满眼的稳定器，第一个在圆弧起在0-90°的二维圆弧井眼中，分析计算各稳定器与井壁的接触情况和接触力大小-If a drill collars, each with an eyeful of 10m stabilizer, the first in a two-dimensional circular arc starting in 0-90 borehole, analysis and calculation of the stabilizer and the bore

edem接触程序，用于计算各种模型的接触力-edem modle

用于ABAQUS滚动计算求解动态接触力，需要使用者对FORTRAN77有一定掌握(For rolling calculation of ABAQUS to solve dynamic contact force, users need to have a certain grasp of FORTRAN77)
