Casing centralizers are generally divided into two types: elastic centralizers and rigid centralizers, and sometimes they can be referred to as semi-rigid. Most of the rigid centralizers have a larger inner diameter than the casing, and they are inserted from the male buckle and then fastened. There are also end-section forms, which are rarely used on site. Materials can be cast steel, aluminum alloys, and high-performance polymers.
The elastic centralizers are of braided and welded types. Generally, for the convenience of fixation, they are of several-lobed type connected by hinges. After the casing thread is connected, it can be set on the casing coupling to prevent the centralizer from moving up and down; If it is not used on the coupling, the elastic centralizer must use a clamp, the clamp is fixed at a certain design position of the casing, and the elastic centralizer is sleeved at both ends of the clamp. If the welded elastic centralizer is not hinged, it can only be inserted through the pin end of the sleeve, and then fixed with a separable clamp.
