4. Gate valves (Z series) – Slab or expanding gate. Metal‑to‑metal or soft seat. Manual, bevel gear, or hydraulic.

5. Plug valves (X series) – Non‑lubricated, pressure‑balanced. Quarter‑turn operation.

6. Chokes (J series) – Adjustable positive or needle/seat. Manual or remote hydraulic control.

7. Hydraulic control units (HCU) – For BOP and tree actuation. Accumulator with manual pump backup.

Applications – Where Our Drilling & Completion Equipment Is Used

We supply integrated drilling and completion equipment for:

• Conventional oil & gas wells (land & offshore) – Standard pressure (5,000 PSI) carbon steel trees. ZJ‑50 or ZJ‑70 rigs.

• High‑pressure / deep wells (10,000‑15,000 PSI) – EE or FF material class. FRAC trees for multi‑stage fracturing.

• Sour gas (H₂S) wells – All wetted parts in stainless steel or Inconel. PR2 testing.

• Arctic / permafrost wells – Low‑temperature carbon steel (-46°C or -60°C). Insulated wellhead.

• Coal bed methane (low pressure) – 2,000‑3,000 PSI wellheads. ZJ‑30 drilling rig.

• Enhanced oil recovery (steam injection) – Thermal wellheads with extended high‑temperature seals.

• Abandonment / P&A – Single BOP stack with cutting tool. Wellhead removal tools.

Why Choose SJ Petro for Drilling & Completion Equipment?

• One source, end‑to‑end – From rig to tree, we manufacture everything. No interface gaps, no multiple purchase orders.

• Sinopec‑backed quality – Direct subsidiary of China’s largest oilfield equipment group. API monogram available on request.

• 80+ years of field experience – Thousands of wells equipped. Our equipment is documented to last 20+ years with proper maintenance.

• Custom engineering – Need a non‑standard flange drilling pattern? A special hanger material? Just ask. Our 314‑engineer team can modify any component.

• Integrated documentation – One binder containing all manuals, test certificates, and drawings for the entire drilling and completion package.

• Global logistics & field service – We ship to 30+ countries and can send technicians to commission both drilling and completion equipment.

• Competitive pricing – Volume manufacturing and integrated engineering reduce cost. You save 15‑25% compared to buying drilling and completion equipment separately from different brands.

• Warranty – 12‑18 months on drilling equipment, 24 months on wellhead and tree (excluding wear parts). Unified warranty – no finger‑pointing.

Frequently Asked Questions (FAQ)

Q1: Can you supply both the drilling rig and the wellhead for the same project?
Yes – that is our specialty. We can quote a complete package: rig, BOP, wellhead, tree, and accessories. The pressure ratings and connections are matched from the rig floor down to the production line.

Q2: Do your drilling rig and wellhead share the same API monogram?
We can provide API monogram on each component separately if you require. Most operators accept our ISO 9001 certification plus the individual component test reports. For offshore, we work with ABS, DNV, or BV for third‑party witness.

Q3: What is the typical lead time for a complete drilling and completion package?
Drilling rig (ZJ‑50): 8‑10 months. BOP stack: 4‑6 months. Wellhead and tree: 4‑5 months. If ordered together, we plan the delivery so that the completion equipment arrives when the rig reaches total depth. Typical coordinated delivery: 10‑12 months.

Q4: Can you provide training for our crew on both drilling and completion equipment?
Yes – we offer a combined training program: 2 weeks on drilling rig operation (drawworks, top drive, mud pumps) and 1 week on wellhead/tree installation and maintenance. Training can be at our factory, your site, or both.

Q5: What documentation do you provide for regulatory approval?
For the drilling rig: API 4F, 7K, 8C certificates, load test reports, material certificates, and electrical schematics. For completion equipment: API 6A PR2 test reports, material traceability (EN 10204 3.1), NDE reports, and hydrostatic test charts. We help you compile the submission package.

Q6: Do you offer spares packages for both drilling and completion equipment?
Yes – we prepare a "first‑fill” spares list based on your expected runtime. Common items: brake pads (drilling), seal kits (BOP & tree), gate valve seats, and stem packing. We can consign spares at your warehouse or our regional hubs.

Q7: Can you integrate third‑party components (e.g., a specific top drive or valve) into your package?
Yes – we are equipment agnostic. If you prefer a specific brand of top drive or wellhead valve, we will procure it and integrate it into our rig or tree, including all interface adapters and control system programming. You still get one warranty from us (except for the third‑party item).

Q8: What is the typical cost of a complete drilling and completion package?
It varies widely by depth, pressure, and automation level. As a rough guide: Land package (ZJ‑50 rig + 5,000 PSI wellhead + single tree) – 6‑8million.Deepwell(ZJ‑70+10,000PSItree)–6‑8million.Deepwell(ZJ‑70+10,000PSItree)–10‑12 million. Offshore package is higher. Request a firm quote with your well data.

Q9: Do you offer financing or lease options for a complete package?
Yes – we work with international leasing companies to offer equipment financing and operating leases. Leasing the drilling and completion equipment together often qualifies for better rates than separate leases.

Q10: How do I get a proposal for integrated drilling and completion equipment?
Email integrated@sjpetro.com with:

• Well depth, casing program, and expected pressure
