Definition - What does Bow-Spring Centralizer mean? Bow-Spring Centralizer is a bow-shaped metal strip used to centralize the casing in a borehole so as to improve the efficiency of cementing. If the casing is touching the formation at any part of the hole, then cement slurry would not pass through the area of contact resulting in a poor cementing job.

The, spring, characteristic of the bows allows the semi-rigid, centralizers, to compress in order to get through tight spots and severe doglegs. The double-crested bow provides restoring forces that exceed those standards set forth in the API specifications and therefore exhibits certain features normally associated with rigid, centralizers, class.

The purpose of a casing ,centralizer, is to facilitate running casing to the desired depth and to assist in centring the casing in the wellbore. One of the main objectives of centralizing a casing string is to facilitate a good cementing, thereby isolating fluids from different zones. A bow-,spring centralizer, can be constructed in various ways, using
