New API Centralizer Oil Gas Well Drilling Casing Centralizer
Product name: casing centralizer
Product classification:Bow-spring centralizer,Rigid roller centralizer,Cast aluminum centralizer
Product overview:
Casing centralizer is one of the necessary conventional casing accessories, upon well operationscompletion, the rational use of casing centralizer can play the role of:
Reducing lower casing resistance phenomenon, making the casing smoothly down to the design position;
Making casing centralizer centered within the well|; Reducing the sticking phenomenon to make the annular space hydrostatic pressure balanced;
Reduce channeling, improve the mud replacement efficiency, thus improve the cementing quality.
The reset force of double bow type centralizer is higher than that of single bow centralizer, centering centering performance is better than that of single bow type.
Bow-spring centralizer
1.These Centralizers are designed for High Restoring Force and Low Starting Force for centralizing the casing pipe in a Vertical, Horizontal and Deviated well
2.Premium quality Bows are made of special alloy steel and hot formed in totally controlled heat treatment plant to achieve the uniform hardness all over
3.Spec and performance index of bow spring casing centralizer meet API Spec 10D. The woven centralizer is connected by pin when in use, the unfolded centralizer can be stacked flatly for convenient storage and transportation.
Rigid roller centralizer
Rigid casing centralizer is used in deviated wells and horizontal wells. There are several blades on the rigid roller centralizer that can keep casing from contacting the wellbore wall
Roller rigid centralizer which is most suitable for highly deviated wells and horizontal wells has two or three rollers in each blade. It can change slipping friction to rolling friction, so the Roller rigid centralizer greatly reduces the friction between casing and wellbore wall and let casing go to desired position smoothly
Cast aluminum centralizer:
The smooth spiral 360 overlap solid vane design of centralizers provide max wall contact will not damage wellhead equipment, has high impact and shock resistance comand fluid swirl. The 30slope from the body to the height of the vane will eliminate scraping, or digging into the formation.
The solid cast aluminum centralizers bine with high tensile and yield strengths
