Why Choose SJ Petroleum Machinery / Sinopec Oilfield Equipment for Deep Oil & Gas Operations?

1. A Manufacturer, Not a Middleman

This distinction matters. Many equipment suppliers are aggregators — they buy components from multiple manufacturers and assemble them under their own brand. SOFE is a manufacturer, with 16 proprietary production lines, a state‑recognized technical center, and national R&D platforms for cementing and fracturing equipment [6†L14-L17][6†L20-L21]. The company holds its own intellectual property on drill bits & tools, drilling rigs, cementing and fracturing units, and steel pipes [6†L21-L22].

When you buy from us, you're buying direct from the manufacturer.

2. The Sinopec Group Backing

SOFE is part of the Sinopec Group — one of the world's largest energy companies and a Fortune 500 organization. That's not just brand recognition; it's access to the full engineering, R&D, and quality resources of a global energy major.

3. Over 40 Years of Deep Equipment Engineering

SOFE has been developing oilfield equipment since 1941 (through its legacy manufacturing facilities). The company has accumulated decades of experience specifically in deep and ultra‑deep oil and gas equipment — culminating in the XJ2750 10,000 m workover rig, ZJ90DB 9,000 m drilling rig, and other ultra‑deep technologies.

4. International Proof — Not Just Domestic

Deep oil and gas equipment from SOFE and SJ Petroleum Machinery has proven itself outside China. Six ZJ90DB deep well drilling rigs are currently operating in Kuwait for KOC, with all six started ahead of schedule [11†L3-L5]. Equipment has been exported to more than 40 countries, including the Middle East, Russia, Africa, Southeast Asia, and the Americas.

5. Full‑Line Provider for Deep Operations

Unlike specialists who focus on only drilling or only well intervention, SOFE provides the complete equipment set for deep oil and gas operations — from initial drilling through completion to ongoing workover and intervention. The product line covers deep well drilling rigs, ultra‑deep workover rigs, high‑pressure snubbing units, deep well coiled tubing, HPHT fracturing equipment, and all the downhole tools and pressure control equipment in between.

6. API Certification Across Multiple Product Lines

SOFE maintains API certification across its product range, including API Q1, API 6A, API 17D, and API certifications for drill bits, tubing, casing, pumping units, and drilling tools. Jiangcheng has successfully passed 2025 API audits for API Q1 / ISO 9001, roller bit logo supervision audits, subsea wellhead equipment API 17D logo supervision audits, and diamond bit logo recertification audits.

7. Customization — Not One‑Size‑Fits‑All

Whether you need a desert‑rated rig for the Middle East, a low‑temperature package for Siberia, an offshore configuration with DNV certification, or a grid‑electric unit for emissions‑sensitive operations — SOFE customizes to the specific well conditions and regulatory environment of your operation.

8. Full Lifecycle Service

SOFE's service model includes on‑site commissioning, operator training, spare parts availability, remote troubleshooting, and preventive maintenance planning — delivered through an international service network that has supported equipment in more than 40 countries.

Frequently Asked Questions (FAQ)

Q1: What does "deep oil and gas operation equipment” mean in this context?

It means equipment designed specifically for wells requiring intervention at depths beyond 5,000 m (and up to 10,000 m), pressures exceeding 35 MPa (up to 105 MPa), high temperatures (above 150°C), and challenging operating environments — including deep water offshore, arctic regions, and high‑pressure shale plays. The term encompasses drilling rigs, workover rigs, snubbing units, coiled tubing units, fracturing equipment, downhole tools, and pressure control equipment used in these extreme conditions.

Q2: What wells are in the "deep oil and gas” category?

Industry definitions vary, but for our equipment, "deep” typically means wells with depths exceeding 5,000 m. "Ultra‑deep” means wells exceeding 7,000 m. The XJ2750 workover rig is rated for 10,000 m depth [9†L6-L8]. The ZJ90 drilling rig is rated for 9,000 m depth .

Q3: What pressure ratings are available for deep well equipment?

For snubbing and well control equipment: up to 105 MPa (15,000 psi) static seal rating. For fracturing equipment: up to 3,000 HP, with electric fracturing systems operating at pressures suitable for deep well stimulation. API 6A wellhead equipment is available across standard pressure ratings from 5,000 psi to 20,000 psi.

Q4: Can this equipment handle HPHT (high‑pressure high‑temperature) conditions?

Yes. The deep well equipment covered here is specifically engineered for HPHT conditions — high downhole pressure (up to 140 MPa, depending on configuration) and high downhole temperature (above 150°C). The "four super” technology platform — ultra‑high‑pressure structure, ultra‑high‑hard material, ultra‑high‑energy control, and ultra‑high‑precision manufacturing — was developed precisely for HPHT applications.

Q5: Does SOFE offer deep water drilling and workover equipment for offshore operations?

Yes. SOFE offers a variety of offshore workover rigs, drilling rigs, jack‑up platform rigs, and submersible platform rigs with 30+ years of experience [17†L4-L8]. The 9,000 m offshore drilling rig system achieves a hook load of 6,750 kN and meets the requirements of 300‑foot and 400‑foot platforms.

Q6: What’s the maximum depth your coiled tubing units can reach?

With 2″ OD tubing, our coiled tubing units can reach up to 8,000 m in a single continuous run. For 2⅜″ OD tubing, reach is approximately 5,500 m. The actual maximum reach depends on tubing grade, well profile, and downhole conditions — our engineering team can provide depth‑specific calculations for your well.

Q7: Are your rigs certified for export to the Middle East?

Yes. Six ZJ90DB deep well drilling rigs have been successfully deployed in Kuwait for Kuwait National Petroleum Company, all started ahead of schedule [11†L3-L5][19†L6-L8]. Equipment can be provided with API, GOST, and CE certification to meet regional standards .

Q8: Do you offer electric drive options for deep well equipment?

Yes. For workover rigs, the XJ900 fully electric drive rig achieves zero emissions with a 70% reduction in energy consumption compared to conventional rigs. For fracturing, super power electric fracturing equipment has been successfully developed and deployed. For coiled tubing, all‑electric drive configurations are available on request.

Q9: What is the typical lead time for a custom deep well rig?

Lead times depend on the specific configuration, pressure rating, and current production schedule. For standard ZJ series drilling rigs, typical lead time is 9–12 months from order confirmation. The ZJ90DB project in Kuwait, for example, required 9 months from project launch to first rig delivery.

Q10: Do you provide training for operators on deep well equipment?

Yes. We provide on‑site training during commissioning covering equipment operation, safety procedures, maintenance, and emergency response. Training duration is tailored to crew experience and equipment complexity — typically 2–4 weeks for deep well drilling rigs and 1–2 weeks for workover or coiled tubing units.

Q11: What after‑sales support is available for equipment operating outside China?

SOFE has established an international service network, with representatives and after‑sales service centers in multiple countries including Indonesia and Russia [16†L6-L7]. Support includes on‑site commissioning, remote troubleshooting, spare parts supply, and preventive maintenance planning.

Q12: What warranty is provided on deep well equipment?

Standard warranty is 12 months from commissioning, covering manufacturing defects in materials and workmanship. Extended warranty packages are available. For major rig projects like the ZJ90DB delivery to Kuwait, SOFE provides an integrated support package including commissioning, training, and maintenance support.
