Abstract (en)

A centering device for casings of wells for the production of hydrocarbons, having a structure with modular elements composed of two head elements (2,3) that can be mutually coupled in an interlocking manner and of at least one intermediate extension element (8), also provided with parts (9,10,11,12) for interlocking coupling with the respective head elements (2,3). The device allows the centering device with the most suitable length for the specific operating needs encountered at the site to be produced directly at the site and at the time of its use.
