Company Introduction
Our company is committed to study the unconventional oil and gas equipment, and oil and gas exploration equipment under special environment such as offshore, desert, shallow, rainforest and cold weather (polar region). At the same time, mechanization and intellectualization of equipment are improved and developed continuously. We developed the cold weather drilling rigs that can adapts to the 45℃ to -60℃ temperature, the series of drilling rig are exported to high-end market such as Russia and Canada. The truck-modular rigs and free-standing drilling rigs can meet the different requirements from the customer.
FRT regards continuous learning ability as one of the company’s core competitiveness and provides regular training to employees to enhance their comprehensive abilities and skills.
