Frequently Asked Questions (FAQ)
Q1: Is SJ Petro an API‑certified manufacturer for both drilling rigs and downhole tools?
A: Yes. SJ Petro maintains active API monogram licenses for drilling equipment (API 7K, 4F, 8C), wellhead and fluid control products (API 6A, 16C), and Kingdream downhole tools (API Spec 7‑1). Complete certification documentation is included with every shipment.
Q2: What is the relationship between SJ Petro and Kingdream downhole tools?
A: Kingdream is the downhole tool brand of Sinopec Oilfield Equipment Corporation, manufactured under the same API‑certified quality system as SJ Petro's drilling rigs and surface equipment. This provides true one‑stop supply from a single quality management system.
Q3: What is the typical lead time for a complete drilling rig order?
A: For a standard ZJ series AC VFD rig, lead time is 8‑10 months from order confirmation to FOB port shipment. Workover rigs typically require 6‑8 months. Custom desert or Arctic‑rated rigs may require 10‑12 months.
Q4: Does SJ Petro provide third‑party inspection?
A: Yes. Third‑party inspection by BV, SGS, DNV, ABS or any certified agency is welcome at any stage of manufacturing. SJ Petro provides full access to manufacturing facilities and can arrange witnessed testing at the customer's request.

Q6: Can SJ Petro supply Arctic‑rated drilling equipment?
A: Yes. SJ Petro has delivered 11 low‑temperature drilling rigs to Rosneft and three ZJ40 cold‑weather rigs to Orienburg Drilling Company. These rigs are rated for -45°C continuous operation with storage to -60°C, qualified in the company's national‑level low‑temperature impact testing laboratory.
Q7: Does SJ Petro manufacture desert‑rated drilling rigs?
A: Yes. Desert‑rated rigs feature 10×10 full‑drive off‑road chassis, desert tires, high‑efficiency cooling systems, and heavy‑duty air filtration for 55°C ambient operation. SJ Petro has delivered desert rigs to Libya, Saudi Arabia and other Middle Eastern and North African oilfields.
Q8: What is the maximum depth capacity of SJ Petro drilling rigs?
