Product Description

Rigid centralizers are mechanical devices used in oil and gas drilling engineering, usually made of high-strength alloy steel or composite materials. Its core structure includes:
Bow-shaped spring sheet: ADAPTS to different well diameters through elastic deformation;
Support ring: Fixes the position of the casing to prevent eccentricity;
Connection snap: Fits tightly with the outer wall of the casing to ensure stability.
Ii. Core Functions
Centering positioning: Force the casing to be placed at the center of the wellbore to avoid cementing quality defects caused by wall sticking.
Improve cementing efficiency: Ensure uniform distribution of cement rings and reduce the risk of trench crossing;
Extend well service life: Reduce casing wear and enhance pressure resistance capacity (Reference standard: GB/T 19831.3-2023).
Iii. Classification and Selection
Spiral
It has strong rotational guidance and low frictional resistance
Horizontal Wells, long-displacement Wells
Straight bar style
It has a simple structure and high pressure-bearing capacity
Vertical Wells, high-temperature and high-pressure environments
Degradable
Environmentally friendly materials that decompose automatically after operation
Development of sensitive strata such as shale gas
Iv. Industry Applications
Oil and gas field development: Conventional drilling, completion of horizontal shale gas Wells;
Geothermal engineering: Ensuring the safety of casing groups in high-temperature environments;
Deep-sea drilling: Anti-corrosion design ADAPTS to high-salinity environments.
Technological trends: Currently, it is developing towards intelligence (such as built-in sensors for stress monitoring) and lightweight (titanium alloy applications).
