Oilfield Cementing Tool Casing Accessories Casing Centralizer API Standards

Oilfield Casing Centralizer Technical Specification:

    The welded elastic centralizer produced by our company has the characteristics of simple structure, reliability, high strength, good spring performance, and easy on-site use. It can be widely used in the casing construction of vertical wells or inclined wells.

    Centralizer The centralizer is a cementing tool. It is simple to manufacture, has beautiful structure and strong centralizing force. It overcomes the shortcomings of the original welded centralizer that is prone to desoldering. It is a centralizer that can ensure the quality of drilling and cementing. There are many types of centralizers, which can be divided into roller type, slider type, automatic reversing type, etc. according to their structure. Centralizers with different structures and materials are suitable for different types of oil wells with eccentric wear. The key technology for using centralizers to prevent eccentric wear is the location, spacing and number of centralizer installations. The starting force and restoring force of the centralizer comply with API standards.

    Certification: API&ISO
    Packing: carton, fumigation-free wooden box, iron box (containing product instruction manual and certificate).

Oilfield Casing Centralizer Parameter:

  Casing Size O.D.: 4-1/2 ~ 20 in (114 ~ 508 mm)

  Hole Size O.D.: 6 ~ 26 in (165 ~ 680 mm)

Oilfield Casing Centralizer Application:

    The function of the casing centralizer is to ensure the centering of the casing in the wellbore, so that the cement between the casing and the well wall is firmly bonded, and to ensure high-quality cementing quality. If the casing centralizer contacts the formation at any part of the wellbore, the cement slurry will not pass through the contact area, resulting in poor cementing, so this is an important device.

Oilfield Casing Centralizer Features:

  (1) Hinge design: Due to the hinge design, the centralizer is very convenient to install and use, and can be installed in any position of the casing in conjunction with the clamp.

  (2) Sufficient elasticity: It is pressed by a mold. The centralizer spring piece has undergone special heat treatment to ensure sufficient reset force. When the casing is lowered to the bottom of the well, even the minimum reset force can resist the lateral pressure of the casing and achieve centralization. effect.

  (3) Special structure: Due to the use of ring-shaped textile structure, the performance is stabilized. The entire centralizer has no welding, no rivets, and a solid structure, which overcomes falling pieces and welding defects.

  (4) Starting force and reset force are in compliance with API standards.

  (5) Easy to install.

Oilfield Casing Centralizer Type:

    Casing centralizers include elastic limit centralizers, swirling casing centralizers, spiral casing centralizers, rigid casing centralizers, drillable casing centralizers, etc.
