Roller Centralizer FEATURES Integrated roller mechanism eliminates the possibility of roller damage during casing installation. Precision machined wear resistant rollers provide excellent rotational performance in high solids mud environments. Roller design helps to minimize plowing or bulldozing cuttings in high angle wells. Minimal roller contact area creates casing standoff which greatly reduces the possibility of differential sticking. If you have any question on casing centralizer, composite centralizer, hinged welded centralizer, aluminum spiral vane solid rigid centralizer and bow spring centralizer etc. We will give the professional answers to you. Manufactured with materials suitable for HTHP well environments. The roller centralizer is with rigid body and straight or spiral blade. The centralizer body is processed by casting, the rollers is alloy steel and then heat treatment. Duo to the low friction feature and roller,it is easy to run between roller and inside of casing. The roller centralizer is used in horzontal or deviated well to centre casing. This kinds of centralizer can remove the wellbore stone and make the mud flow easily. The roller provides high wear resistance and has long life for centralizer. Our centralizer coating is powder baking in high temperature. The roller centralizer sizes are from 4-1/2inch to 20inch,any special sizes are available according requirement.
Single Piece Centralizer Single Piece Bow Spring centralizer is constructed from one piece ensuring high restoring force, uniform hardness and shock absorption. The advantage of the single piece centralizer is that its smooth corner radius reduces friction ensuring that fluids can flow more easily without obstruction.

Solid Body Straight Spiralizer Solid Rigid Centralizer is specially designed to minimize unwanted removal of well cake and to run the casing easily. It is ideal for highly deviated or horizontal wells. In other words, it is absolutely appropriate for Liner Hanger. Solid rigid centralizer is fabricated from supreme quality material steel construction which ensures that extra strength and superior toughness for standoff performance in at affordable price to our customers. If you have any question on casing centralizer, composite centralizer, hinged welded centralizer, aluminum spiral vane solid rigid centralizer and bow spring centralizer etc. We will give the professional answers to you. These centralizers are made shock resistance and with optimum tensile and yield strength. Both the types of solid rigid centralizer are available here:Straight Blade' andSpiral'. By running on the casing OD, they are used to centralize the casing. This casing is to be cemented in the wellbore. This also improves the bonding of cement in the casing. These centralizers are designed in such a way that it reduces the amount of friction created between hole and the casing. This allows the casing to be inserted into the wellbore more easily. Thus, preventing the string of the casing to be stuck. These centralizers are perfectly tested and are appreciated for their quality standoff and usage before they are dispatched.

Reamer Shoe Reamer Shoe is designed specifically to be installed on Casing or Liner and Screen where operators have concerns about potentially difficult wellbore conditions such as, swelling shale's, ledges and washed out areas of wellbore, post drilling and prior to running casing. The aluminum eccentric guide nose climbs ledges and negotiates obstructions while the cutting structure reams out tight spots or obstruction in the wellbore. Compatible with all casing and liner hanger assemblies, our Reamer Shoe provides highly effective protection- against unexpected or anticipated casing and liner running problems, and has been specifically designed for potentially difficult wellbore conditions such as swelling shales, ledges and washed out areas of wellbore. The high strength profiled alloy nose will anchor even in uncured cement to facilitate ease of drill out. The aluminum eccentric nose is easily drilled with both PDC and Rock bits. The chip breaker holes in the nose assembly are designed to create small aluminum chips to avoid â??bird nestingâ?� on the bit. Benefits to customers include improved drill out times without compromising the reaming capabilities, a reduction in NPT and increased opportunities to reach TD.

Stage Cementing Collar Hydraulic Type (Two Stage) Stage Cementing Collar Hydraulic Type (two stage) Hydraulic Stage Cementing Collar is a field-proven stage tool that meets the challenges of cementing holes at any angle with a hydraulically opened port system. It is specifically designed for horizontal sections / formations, the multistage cementing tool can be placed anywhere in the casing string. It is PDC-drillable and field-adjustable shear pins system. When the first-stage shutoff plug lands on the shutoff baffle, increased internal casing pressure hydraulically opens the stage tool, enabling circulation and then second-stage cement to pass though the ports into the annulus above the tool. The closing plug when released, wipes the casing ID clean of cement before bumping on a closing seat. Increased pressure shifts the closing seat downward, releasing locking lugs and closing the tool. A snap ring locks the sleeve in position, ensuring the stage tool remains locked. With 12 years export experiences, our stage collar, stage cementing collar hydraulic type, cementing basket, linger hanger and cementing plug has been welcomed in international markets. Stage Cementing Collar Mechanical Type (two stage) Stage Cementing Collar is used to effectively cement upper sections of the casing string after displacing cement around the lower section. The Multiple Stage Cementing Collar provides a means of opening and closing port holes for cement displacement and positive containment of the cement after displacement. All internal parts are easily drilled, and are firmly held from rotating during drilling. The port closing sleeve is positively locked in position after cementing. After running the Collar to setting depth, the lower section is cemented in the conventional manner except the cement is displaced with the flexible cementing plug furnished with the collar. This is bumped against the shutoff Baffle. A slight pressure build-up of 300-400 P.S.I. will assure plug is seated in Baffle. The port holes in the Multiple Stage Cementing Collar are opened for doing the second stage by dropping the trip bomb and applying approximately 800-1000 P.S.I. pressure. The second stage is displaced with the closing plug which is also furnished with the Tool. When the closing plug bumps approximately 800-1000 P.S.I. pressure will close the port holes.
