摘要

在水平井、大位移井中选用合适的套管扶正器不仅能使套管顺利下入,而且能确保套管在井眼中的居中度,提高固井质量。介绍了几种新型的套管扶正器,并介绍了国内外在水平井、大位移井固井中使用的套管扶正器的性能特点及应用情况,得出了常规的套管扶正器很难满足水平井、大位移井需要的结论。

Abstract

Proper selection of casing centralizer is very important for running the casing to bottom hole in horizontal and extended reach well, and it can improve cementing quality by centralizing the casing in hole. This paper presents several new types of casing centralizer, and their applications in cementing horizontal and extended reach wells. It emphasized that specially designed casing centralizers must be used for the successful cementing in horizontal and extended reach well.
