Product Description
Shaffer Ram BOP 13 5/8"-10000psi Forging Type
The Shaffer Ram Blowout Preventer (Ram BOP) is essential well control equipment for oil and gas drilling, workover, and well testing operations. It precisely controls wellbore pressure, prevents blowout accidents, and provides comprehensive safety guarantees for downhole operations while adapting to various complex working conditions.
Core Features
- Solid Structure & Corrosion Resistance: Main pressure-containing components (body, bonnet, ram block) are manufactured from high-strength, high-toughness alloy steel through casting and forging processes, reinforced by heat treatment. Complies with API Spec 16A and NACE MR 0175/ISO 15156 standards with specialized anti-corrosion treatments for harsh downhole environments.
- Wide Range of Bore Sizes & Pressure Ratings: Available in bore sizes including 7 1/16", 9", 11", 13 5/8", 16 3/4", 21 1/4", and 26 3/4". Rated working pressure ranges from 2000psi (13.8MPa) to 15000psi (103.4MPa) for medium-high to high-pressure operation scenarios.
- Reliable Ram Performance: Features HF-type forged rams (recommended) and S-type split rams. Available in pipe rams, blind rams, shear rams, and variable-bore rams for annular space sealing, full wellbore sealing, and emergency string shearing functions.
- Dual Protection Sealing System: Initial sealing through four key points plus well pressure-assisted sealing. Equipped with secondary sealing mechanism for emergency remediation via grease injection if primary seals are damaged.
- Structure Designed for Easy Maintenance: High support ribs and sand-settling inclined surface reduce friction. Internal buried hydraulic oil circuit prevents damage. Hinged bonnet design facilitates disassembly and maintenance.
- Flexible & Safe Operation Modes: Supports hydraulic control and manual locking. Hydraulic operation completes ram opening/closing in 3-15 seconds. Manual locking secures ram position during long-term well sealing without continuous hydraulic pressure.
Opening Methods & Bonnet Design
Hydraulic Direct Opening
Inject high-pressure oil (8.4-10.5MPa) into the ram opening cavity to push the piston, driving the ram shaft and ram assembly away from the wellhead center.
Hydraulic Opening After Manual Unlocking
First rotate the handwheel counterclockwise to drive the locking shaft to the end, then turn back 1/8-1/4 turn before supplying pressure to the opening cavity.
Hinged Bonnet Opening
Bonnet connects to body through hinge base assembly. Loosen bonnet bolts and rotate bonnet for ram assembly removal and maintenance.
Wellhead Installation & Inspection
Pre-Installation Inspection
- Check flange sealing gasket ring grooves and surfaces for defects
- Confirm ram specifications match downhole drilling tool size
- Verify BOP has passed pressure testing and is qualified
Wellhead Installation Steps
- Apply ISO 13678 compliant thread grease and tighten bolts diagonally in three stages
- Connect hydraulic control pipelines according to opening/closing marks
- Connect manual operating lever and verify locking mechanism operation
Post-Installation Inspection
- Confirm correct BOP installation with body lifting lugs at top
- Test open/close each ram type twice with 2-3MPa control pressure
- Check manual locking mechanism flexibility and mark handwheel rotations
- Verify kill and choke manifold connections and conduct comprehensive pressure test
Usage Methods
- Specialized Operation: Assign dedicated personnel with comprehensive training in BOP operation and maintenance
- Standardized Operating Pressure: Maximum 3MPa for pipe ram testing without string; never close blind or shear rams with string present
- Use of Manual Locking: For long-term well sealing, close ram hydraulically first, then engage manual locking with warning tags
- Regular Inspection & Maintenance: Daily ram operation checks in target zones, blind ram testing after tripping operations, and regular performance testing
- Timely Fault Handling: Relieve pressure before troubleshooting issues like incomplete ram operation or sealing leakage
