In recent years, Jinan Diesel Engine Co., Ltd. (000617) has developed a diesel/natural gas dual-fuel engine and its corresponding generator set specifically designed for oil drilling power. Known for maintaining a high new product contribution rate, the technology has now been recognized by the China Petroleum System Expert Group. This project marks a significant breakthrough, filling a critical gap in the market for high-power dual-fuel engines above 1000KW, both domestically and internationally.
With global energy demand on the rise, the energy crisis is becoming more severe. Natural gas, due to its clean-burning properties and abundant reserves, has emerged as a promising alternative fuel. It not only helps balance the energy structure but also supports energy conservation and environmental protection goals. As the petroleum industry evolves and drilling equipment becomes more advanced, the contradiction between energy shortages and rising drilling costs has become increasingly apparent.
According to industry data, fuel consumption in drilling machinery accounts for over 20% of total drilling costs. Oil drilling often takes place in remote locations where transporting diesel is challenging. However, many oil fields have access to natural gas, which is almost cost-free after minimal processing. This makes it an ideal fuel source for power machinery. Therefore, developing a diesel/natural gas dual-fuel engine tailored for oil rigs has become a pressing need.
The shift from diesel to natural gas in drilling operations can significantly cut costs and improve economic returns. It is reported that CNPC plans to gradually replace traditional diesel engines with dual-fuel engines in rigs where conditions allow, aiming to achieve substantial cost reductions. Once the technology matures and proves reliable, it is expected to expand into the international drilling rig power market.
Beyond oil drilling, these dual-fuel engines can also serve as new power solutions for fixed power generation, natural gas gathering and transmission compressors, and other industrial applications. This versatile technology not only enhances energy efficiency but also contributes to sustainable development in various sectors.
