The predecessor of Nanyang Erji Petroleum Equipment Group Co., Ltd. was the Nanyang Petroleum Machinery Plant of Henan Petroleum Exploration Bureau of Sinopec Group (the second petroleum machinery plant of the Ministry of Petroleum Industry, established in 1969). It was reorganized on June 26, 2004, and was originally The state-owned enterprise was changed to a limited liability company and was changed to a joint-stock company on January 18, 2016.

The company is a national major technical equipment domestic base, a domestic base for oil lightweight drilling rigs, a national innovative enterprise, a high-tech enterprise, a Torch Plan high-tech enterprise, etc. The company has the National Petroleum Vehicle Equipment Standardization Work Department, the National Certified Enterprise Technology Center, the Academician Workstation and the Postdoctoral Research Workstation.

The company's products include more than 200 varieties in 12 series, including vehicle-mounted drilling rigs, skid-mounted module drilling rigs, drag drilling rigs, well repair machines, and well logging equipment. Especially in the 1990s, the concept of light drilling equipment characterized by rapid migration and operation automation was boldly proposed, and it was put into the development of light drilling equipment. The company insists on independent research and development and has developed 3000-meter vehicle-mounted drilling rigs, 4000-meter vehicle-mounted drilling rigs and 4000-meter towed drilling rigs, among which 4000-meter vehicle-mounted drilling rigs and 4000-meter towed drilling rigs meet the users' large tonnage self-propelled drilling equipment. High-end demand provides advanced equipment for factory drilling.

At the same time, the company is also committed to developing unconventional oil and gas equipment and oil and gas exploration and development equipment that meets special environmental needs such as oceans, deserts, mudflats, rainforests and low temperatures (polars), and continuously improves the mechanization and intelligence level of equipment. Developed a full hydraulic coalbed methane drilling rig, providing new solutions for global coalbed methane development; developed a series of low-temperature drilling rigs that adapt to the environmental requirements of -45℃ to -60℃, and were exported in batches to high-end markets such as Russia and Canada; developed an adaptation Small-module helicopter hoisting drilling rigs for tropical rainforest environments, as well as integrated car-sled drilling rigs, rope-free vehicle-mounted (trailing) drilling rigs, etc., meet users' special customization needs.

At present, while maintaining the dominant product position in the industry, the company is actively carrying out engineering and technical services such as oilfield drilling, cementing, and logging, and striving to build the company from the current domestic cutting-edge oil drilling and production equipment manufacturer into an internationally advanced oil and gas Complete equipment system integration and service provider.
