套管扶正器的正确位置，是保证斜井与水平井固井质量的前提。在全面分析安装有多个扶正器套管柱的力学特性的基础上，采用了有初弯曲连续梁的力学模型，用初弯曲纵横弯曲梁理论和三弯矩方程组成的多元线性联立方程组，从理论上解决了斜井和水平井套管扶正器安装位置的正确计算方法，并修正了《API套管扶正器技术规范》（APISpec10D）违背扶正器处套管变形连续性原理和我国原石油部部颁标准《SY5334－88套管扶正器间距计算推荐方法》认为扶正器套管转角为0的不妥作法。
The correct position of casing centralizer is the prerequisite to ensure the cementing quality of inclined shaft and horizontal well. On the basis of comprehensively analyzing the mechanical characteristics of multiple centralizer sleeves, the mechanical model with the first bending continuous beam is adopted, the multiple linear simultaneous equations consisting of the first bending longitudinal bending beam theory and the third bending moment equation , Theoretically solved the correct calculation method of the installation position of the centralizer and horizontal well casing centralizer, and amended the “API Casing Centralizer Technical Specification” (APISpec10D) to violate the principle of casing deformation continuity at centralizer and our country Ministry of Petroleum ministerial standards “SY5334-88 Casing centralizer recommended distance calculation method” that centralizer casing angle of 0 improper approach.
