摘要
多臂井径测井仪是获得油水井套管变形程度的重要工具,利用最优化方法对井径仪所获得的数据进行解释,给出了套管变形截面的近似偏心圆的圆心、最大通径和有效通经.这为进一步解释套管变形提供了科学的依据.
The multifinger logging tool is an important tool acquiring casing deformation degree of water-oil well, The data that logging tool acquiring is interpreted by optimization method, circular center, maximum diameter and efficient diameter of approximate eccentric circle for deformation section are given. It provides scientific basis for interpreting casing deformation;
