Vishal Engineering 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. Hydraulic Setting Tool is specifically designed for horizontal sections/ formations, the multistage cementing tool can be placed anywhere in the casing string. Vishal Engineering Hydraulic Stage Cementing Collar is PDC-drillable and field-adjustable shear pins system. When the first-stage shutoff plug lands on the landing collar, 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 connected to inner sleeve. 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.
FEATURES / BENEFITS:-
Vishal Engineering Stage Cementing Collar can be made from material grades up to 135,000 psi minimum yield, including material suitable for sour gas service.
API & Premium connections are available upon request.
No welds are used on any portion of the tool.
The seals providing internal and external pressure integrity are housed in the stage collar body and remain stationary throughout operation, minimizing chances of their being damaged.
The pressure-relief design prevents fluid trapping and compression between the opening device and the closing plug during the closing phase of the tool’s operation.
The closing sleeve is held in the closed position by an internal lock ring. Both the opening and closing sleeves lock against rotation for easy drill out.
A minimum amount of aluminium and rubber are the only materials encountered during drill-out.
The opening pressure of the stage tool can be adjusted at the rig site to meet well requirements, providing operational flexibility.
The system is PDC-drillable with anti-rotation features on the plugs, stage tool, and landing collar to prevent rotation during drill out, simplifying drill out and saving rig time and associated costs.
