定向井抽油杆柱空间形态的计算方法
Calculation method of sucker rod strings space configuration in directional well
摘要
Abstract
The wellbore trajectory was described by the radius of curvature method, and a finite element model of slender rod was established and solved by the curnode iterative method.The node force and deformation of sucker rod strings also could be obtained by this method with the consideration of multi-supports geometric constraints.Then the differences of spatial configuration of rod strings with various fixation patterns of centralizer were compared.The results show that the eccentric wear position of sucker rod strings and fixation patterns of centralizer could be determined by the solution of 3D configuration of sucker-rod strings in wellbore.关键词
