Casing Centralizer Suppliers and Manufacturers

Casing centralizer Wooden case

Description: Casing Centralizer is a device used to place the casing at the center of the hole so as to improve the efficiency of the cementing. It is an important device because if the Casing Centralizer touches the formation at any part of the hole, then cement slurry does not pass through the area of the contact resulting in a poor cementing job.

The popular styles available are non-welded single bow spring centralizer, and double-bow spring centralizer with high reliable quality, which can be used to replace weatherford centralizer. Spring centralizer characters super-strengthen spring steel model processing, no rivet , no welding 3-section structure for easy transport starting and resetting force conform to api standard easy for installation Rigid casing centralizer As one useful cement tool, rigid centralizer enables casing run easily in wellbore with its shape of stream-lined. There are two kinds of rigid centralizer available: spiral blade rigid centralizer and straight blade centralizer. The material for both kinds of centralizers can be cast steel or cast aluminum. -

Eneroil developed the Solid Body Low Drag Roller Centralizer as axial drag friction reduction tool. The contact area of the rollers with the casing or borehole wall functions well in under pressured conditions, where the risk of differential sticking is high. The Low Drag centralizer with steel rollers helps to avoid ploughing through wellbore material that has settled, alleviating major drag problems in deviated and horizontal wells. Solid Body Low Torque Roller Centralizers are specifically built to run in an inclined or horizontal section. The rollers outside diameter are kept slightly larger than the centralizer blades outer diameter. When casing equipped with Solid Body Low Torque Roller Centralizer runs into the deviated or horizontal hole, sliding friction between the casing and the borehole is converted into rolling friction. In case of irregular hole diameter, the borehole wall has an impact force on the spiral centralizer during running casings, the use of rollers reduce this impact.

Centralizers are mechanical devices that prevent casing from contacting the well bore wall. A continuous 360-degree annular space around casing allows cement to completely seal the casing to the borehole wall.

The single piece centralizers are one piece construction in special high strength steel which imparts excellent hardness and spring action ensuring an unmatched ability to come back to its original shape after undergoing rigorous stress loads conditions. The single piece centralizers are available in size 4-1/2" to 20".Any special sizes or combination can be available on requirment. This centralizer undergoes a special Iron Phosphate coating process to prevent it from rust and coated with special Polyester Powder. It is shipped in assembled condition only. When shipping them,in order to save space and shipment charges for customers,we usually put the smaller size centralizer into bigger size centralizer.

Spring casing centralizer is pressed into shape by mouding instead of welding and rivet. It has the advantages of simple structure, safe and reliable, high strength, good elasticity and convenient use. It can be widely used in vertical and deviated well in the casing work. Starting force and restoring force conform to api standards. Spring casing centralizer is divided into single bow, double bow and three bow. Spring centralizer is composed of circular hoop, bowspring and dowel. Bowspring can reach api standards after heat treatment which material is 65 mn.

Eneroil Offers A Quality Range Of Solid Rigid Centralizers That Is Well Suited For Any Well Bore Which Requires To Endure High Pressure Or Temperature. The Extended Range Includes Spiral Blade Solid Centralizer (aluminium/ Zinc/ Steel) , Straight Blade Solid Centralizer(aluminium/ Zinc/ Steel) , Slip On Welded Spiral Spiraslider, Heavy Duty Spiraslider, Rotating Solid Centralizers & Slip-on Stand-off Band(s-40).

Eneroil offshore has developed its Single piece Bow Centralizer (S12) model to perform satisfactorily in Open hole as well as Cased hole. These are high quality product, developed to meet and exceed API10 D specifications for use in highly demanding downhole conditions. Eneroil's Single piece Glider Centralizer (S12) combines the highest restoring force with zero starting force and zero running force. Single piece centralizer is used to position the casing in the center of the wellbore in vertical deviated and horizontal wells, reduce the effect of channeling by reducing pipe movement before Cement sets in and improving the cement flow, this results in more uniform cement thickness in the well bore. S12 centralizers are one piece construction in special high strength Steel which imparts excellent hardness and spring action ensuring an unmatched ability to come back to its original shape after undergoing rigorous stress loads conditions.

Eneroil's spiral vane thermoplastic centralizers are manufactured using engineered material and are designed for the maximum durability, drag, and friction downhole achievable in a centralizer. Additionally, these centralizers have lower friction factors, a rotational torque reduction, and increased abrasion resistance for a maximum stand-off. Spiral vanes help enhance hole-cleaning by using a maximised flow-by area. The vanes overlap the entire 360° open-hole circumference, which creates a vortex motion to increase fluid velocity with direction. Even without rotation, the vanes are able to induce turbulent flows for an improved cutting and filter cake removal. Eneroils thermoplastic centralizers are a one-piece construction of superior-quality polymer, with optimum tensile and yield strengths, and are able to withstand high well-bore temperatures while providing a maximum horizontal stand- off.

Hinged Non-welded Casing Centralizer Product Description 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 centralizerthat 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
