In recent years, Jinan Diesel Engine Co., Ltd. (000617), a leading manufacturer in the industry, 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 level of innovation and new product contribution, this technology has recently been recognized by the China Petroleum System Expert Group. The project marks a significant breakthrough, filling the gap in high-power dual-fuel engines for drilling applications above 1000KW, both domestically and internationally.
As global energy demand continues to rise, the energy crisis is becoming more severe. Natural gas, with its clean-burning properties and abundant reserves, has emerged as a promising alternative fuel. It not only helps balance the energy consumption structure but also supports energy conservation and environmental protection goals. With the expansion of the petroleum industry and the modernization of drilling equipment, the challenge between energy shortages and the need to reduce drilling costs and improve efficiency has become increasingly pressing.
According to statistics, fuel consumption for drilling machinery accounts for over 20% of total drilling costs. Drilling operations are often located in remote areas where transporting diesel is difficult and costly. However, many oil fields have access to natural gas, which can be used directly as a fuel after minimal processing. This makes it almost cost-free, presenting a compelling opportunity to reduce operational expenses.
Therefore, the development of a diesel/natural gas dual-fuel engine tailored for oil drilling rigs has become an urgent necessity. Utilizing the abundant natural gas available at oil sites instead of diesel can significantly lower drilling costs and bring greater economic benefits.
It is reported that CNPC plans to gradually transition rigs that are suitable for natural gas engines, replacing traditional diesel engines with dual-fuel alternatives. This move aims to achieve substantial cost reductions in drilling operations. Once the technology becomes stable, mature, and reliable, it will be further expanded into the international drilling rig power market. In addition to being used for drilling power in gas-rich areas, these dual-fuel engines can also serve as new power solutions for fixed power generation, natural gas gathering and transportation compressors, and other industrial applications in China.
