新型防卡扶正器结构设计、安全性分析及效果评价

The structural design,safety analysis and effect evaluation of a new anti-stick centralizer

针对传统橡胶扶正器在测井作业过程中存在的问题,设计了一种新型防卡扶正器。安全性分析、室内模拟阻力测试及实验井评价结果表明,新型扶正器结构稳定可靠,能大幅度减小阻力、降低仪器遇卡的可能性,具有一定的推广应用价值。

A new anti-stick centralizer is designed in view of problems existing during the using of traditional centralizer. The safety analysis, simu lated resistance test in lab and effect evaluation in test well have proved that the centralizer is stable and reliable in structure, can reduce the resistance substantially and minimizes the sticking possibili- ty, so that it has a certain value for promotion and application.
