Analysis of the gap between domestic and foreign petroleum instruments

"Before the experiment, we really wanted to buy domestic equipment, and the price was definitely more cost-effective, but according to our experience, domestic equipment is prone to problems after using it for a period of time. Therefore, we would rather spend a little more money to buy longer Imported instruments. "A scientist said. Presumably this is also the common feeling of many users of analytical instruments in China. It can be seen that there is an undeniable gap between Chinese petroleum instrument products and foreign products.

So, what are the differences between domestic petroleum instruments and imported products?

Using time and measuring accuracy are orders of magnitude different

The China Association for Science and Technology released the survey results organized by them in March 2007: the main analytical instruments in China Petroleum Instruments, more than 90 types of analytical instruments are being used in the society, and more than 20 types of products can be produced in China, less than the total 1/3. Among them, there are more than 80 kinds of life science special instruments, and there are only 6 kinds of commercial life science special instrument products in China. There are about 10 kinds currently under development, which is far from the market demand. This is a gap in quantity.

Technically, most of the existing domestic low-end products can be replaced with imported products, and the reliability indicators of high-end products, that is, the average trouble-free operating time is about one to two orders of magnitude different from foreign products.

In terms of measurement accuracy, existing domestic products are generally one order of magnitude different from foreign products. Because China's research on the basic technology and manufacturing technology of petroleum instruments is not enough, some key technologies that affect reliability, such as precision machining technology, sealing technology, welding technology, etc. have not yet been well solved, leading to products, especially high-end products The performance is not stable and reliable enough.

Functionally, at present, foreign products are highly intelligent. By digitally processing the original information, the influence of external interference on the information is better excluded, and the product's environmental resistance and measurement authenticity are improved. The existing domestic products are still less intelligent.

In addition, the network of products has entered the practical stage abroad, while China is basically in its infancy, which makes the performance and functions of products lag behind.

According to relevant experts, the update cycle of foreign products today is about 2-3 years. New technology reserves can often be advanced to 10 years. However, Chinese companies often adopt the introduction of foreign technology to update the first-generation products. After the introduction, they cannot digest and absorb them well, and they have few original achievements in the development of new products. Some products using new principles are still blank in China. Although there are achievements in tracking new technologies at the research institutes, it is quite difficult to integrate industrialization with enterprises, resulting in long product technology update cycles.

In addition, domestic petroleum instruments lack a dedicated solution developed for the target. In recent years, the development trend of measurement control and instrumentation in foreign countries is to develop software products that closely integrate instrumentation and application objects, and ultimately provide users with personalized solutions. For example, for the performance calculation software of 6 × 10'kW thermal power generating units, optimization software for refining processes, and graphics processing software specially used for medical instruments, domestic enterprises have not yet formed an industry in this regard.

Weak foundation and unsettled institutional mechanisms

Experts participating in the survey introduced that petroleum instruments belong to the high-tech industry, and China relies on the advantage of low labor costs in industrial development, and this advantage is difficult to play a role in the petroleum instrument industry.

They believe that there are several reasons for the gap between China's petroleum instrument products and foreign countries. The operating mechanism of China's enterprises has not yet fully adapted to the requirements of the development of a market economy. In the process of development, a group of key state-invested enterprises faced the grim situation of aging products and the loss of technical personnel. After the restructuring, although the production and management have improved, the scientific and technological innovation capacity is still insufficient; a batch of mechanism innovations and operations Flexible private enterprises are gradually becoming a new bright spot, but the vast majority of enterprises are small and medium-sized enterprises, small in scale, and most of them have not yet mastered advanced core technologies and have few innovation achievements. They cannot yet compete with large foreign companies.

First of all, the country's overall organic combination system of production, learning, research, and other policies and policies has not been formed, the rate of innovation results is low, and the application of technology is poor. In the early stage of reform and opening up, the gap between the petroleum instrument industry and foreign countries was wide, and companies generally sought out technology sources. Although there have been recent changes and some companies have stood out, in general, the company's independent innovation technology results have not been well combined with applications, and large companies have difficulty growing. .

China's scientific research institutions have many scientific research achievements involving measurement and control technology and related instruments, but their practicability is poor. The depth and intensity of research on related manufacturing technologies, especially core process technologies, are insufficient, the workload of secondary development is large, and the conversion rate of results is low. High- and mid-range instrument products and systems involve a certain depth of application technology in different fields. Foreign companies have professional departments and experienced application talents, while China's petroleum instrument companies are often unfamiliar with large-scale engineering processes and lack application technology integration capabilities. . Therefore, it is difficult to produce high-end products.

Second, the country lacks a strong research support system. The petroleum instrument industry has many varieties and small batches, which requires long-term and persistent investment. However, the current national investment channels are scattered and it is difficult to focus. Enterprises can not compete in the same way as foreign companies in accordance with the rules of the market economy, and they lack the strategic investment in research resources. At the same time, the market environment required for the marketization of new technologies has not yet been perfected.

Experts said, "Because the system and mechanism have not been rationalized, China's petroleum instrument industry naturally lacks high-level compound talents and comprehensive talents who are familiar with and proficient in various disciplines. Petroleum instrument science and technology not only involves a wide range of disciplines, but also Only those who can discover, utilize, and integrate the latest scientific and technological achievements such as new principles, new concepts, new technologies, new materials, and new processes as soon as possible can design and manufacture world-class measurement and control and petroleum instrument products. Talent shortage, natural Affect the development of the industry. This is undoubtedly also an important reason for the gap between domestic petroleum instruments and imported products.
