It is a professional manufacturer and service provider focusing on high-performance downhole tools. The company focuses on three core product lines: drilling jars, hydraulic oscillator, and Heavy-Duty Shock Absorbers, providing integrated solutions covering manufacturing, sales, maintenance, and technical support for conventional and unconventional oil and gas operations. Meanwhile, the company has established a comprehensive maintenance and technical support network covering both domestic and international markets.The 30-acre (approximately 20,000 square meters) base located in Jinma Logistics Park, Chengmai, Hainan, is the company's exclusive international service and maintenance base. Strategically located to serve the overseas market, this base is equipped with equipment for downhole tool inspection, maintenance, refurbishment, pressure testing, and rapid turnover. Leveraging its proximity to major ports and international logistics channels, the Hainan base shortens the delivery and service cycles for global customers, minimizing operation downtime and improving project efficiency. For the domestic market, the company has manufacturing and service centers in Xindu (70 acres), Qingbaijiang (48 acres), and Yibin (29 acres) in Sichuan Province, and maintenance workshops in major oilfield areas such as Karamay, Turpan, Korla, and Huatugou.

The company continuously enhances its manufacturing strength and R & D capabilities through long-term industry-university- research cooperation with Southwest Petroleum University. The ongoing R & D work focuses on vibration control, anti-sticking technology, and structural optimization of downhole tools to improve their performance under complex well conditions. The company's production system integrates raw material inspection, precision machining of key components, assembly, performance testing, and final quality verification to ensure full-process quality control. Supported by certification systems such as ISO 9001, ISO 14001, ISO 45001, and API 7-1, the company ensures that its drilling jars, hydraulic oscillators, and heavy shock absorbers maintain stable and reliable performance under high-temperature, high-pressure, and complex geological environments. Through continuous technological innovation, large-scale manufacturing capabilities, and extensive on-site application experience, the company provides reliable and cost-effective downhole tool solutions for global customers.
