“I have hosted many technical and product appraisal meetings, but today I am excited to be able to make factory acceptance for this most advanced deep-sea oil rig in the world. For me, the opportunity is rare...” This is At the end of the year, Zhong Shude, a senior expert in China's oil drilling rig industry, held a section on the 12,000-meter deep well land oil rig factory acceptance meeting held on November 15.
On this day, China's first 12,000-meter deep well land oil drilling rig with independent intellectual property rights developed by China National Petroleum Corporation Baoji Petroleum Machinery Co., Ltd. passed the factory acceptance. Zhong Shude is obviously very excited. He said: "The successful development of the 12,000-meter drilling rig has broken the long-term blockade of foreign high-end equipment technology to China and filled the domestic gap. It is a milestone in the history of China's oil drilling equipment development."

The core components are basically localized

On November 15th, on a rainy winter day, the reporter came to the rig test well site of Baoji Petroleum Machinery Factory and saw the main structure of the 12,000-meter rig – standing 52 meters high on the 12-meter-high giant square base. K-type structural derrick. Just 10 meters away from it, stood the first 9000-meter ultra-deep oil rig in China that was successfully developed in December 2005.
“From the appearance, the structure of the 12,000-meter rig and the 9000-meter rig is very similar, but because of the different depths of their drilling, the configuration and manufacture of many key components require a lot of effort to re-develop.” Baoji Petroleum Machinery Factory Assembly Ma Yiping, the director of the complete branch factory, pointed to the 12,000-meter drilling rig and told reporters that “two years ago, although we have developed our own 9000-meter drilling rig; but 12,000 meters is not only a challenge for Chinese professionals, but also in the world. A difficult problem to break."
It is understood that before this, only the United States in the United States in the 1980s produced a 12,000-meter analog-controlled DC-driven drilling rig, and this rig produced 20 years ago, regardless of system configuration, technical parameters, or handling performance, Both have a big gap with the 12,000-meter all-digital AC frequency conversion land drilling rig developed in China.
"The biggest highlight of this 12,000-meter rig developed by China is the integration of the most advanced technology at home and abroad." Ma Yiping told reporters that in addition to diesel generators, this rig is introduced into the products of Caterpillar Inc. of the United States. The key components are all developed by China, and the core components are basically localized. The independent research and development of this special deep well rig technology has achieved many major breakthroughs in China.
According to Ma Yiping, the research on the overall technical scheme and integration technology of the drilling rig is not only exclusive in the country, but also in the international level. The drilling rig first developed a derrick and base with a carrying capacity of 900 tons, achieving low-level installation. The overall power of the winch was lifted; the 6,000-horsepower ultra-high-power winch was developed for the first time, with high reliability and good economic operation. The first development of a 900-ton crane and a cruiser was developed for the first time. The first development capacity was 900 tons. Large hooks and rings that can meet the requirements of minus 40 degrees Celsius; the first development of a faucet with a carrying capacity of 675 tons and a temperature of minus 40 degrees Celsius; the first development of a dead rope holder with a load capacity of 720 tons and low temperature resistance... At the same time, the drilling machine With the reliability study of the 2200 hp high-pressure mud pump wearing parts, the research on the special AC frequency conversion motor has also made a major breakthrough.
The world's pioneering work

Why develop high-end oil drilling equipment technology like the 12,000-meter drilling rig? In the face of the reporter's question, Zhang Yongze, general manager of Baoji Petroleum Machinery Co., Ltd., replied with a short but meaningful statement: "The 12,000-meter drilling rig is to meet China's demand for deep oil and gas resources exploration and improve the development level of China's oil drilling equipment. Developed with competitiveness in the international market."
The reason why Zhang Yongze’s answer is described by “meaningfulness” is because the development of the 12,000-meter rig is actually forced by the contradiction between the actual demand and the objective situation, and it is a choice that is “forced”. Zhang Yongze told reporters that on the one hand, after decades of exploration and development of China's oil and gas resources, the exploration and development of shallow and medium-level underground oil and gas resources has been relatively high, while the deep, ultra-deep, and deep-deep oil and gas resources are affected by drilling equipment. The constraints are still relatively unfamiliar. The growing tensions in global oil and gas resources and the growing demand for oil and gas resources require us to break the technical bottleneck and demand energy from deeper strata.
"On the other hand, oil drilling and production equipment is an important strategic equipment resource of the country. If it lacks independent technology, it is unrealistic to rely solely on the technical resources of other countries." Zhang Yongze said a turn, seriously said, "for a long time Foreign high-end petroleum equipment technology monopolizes the domestic market, and imposes a blockade on China's disguise. They refuse to supply to China at unbearable prices or for various reasons. Therefore, we realize that we must rely on China's own strength for R&D. This kind of self-designed and self-developed product can truly guarantee the energy security of our country and guarantee China's right to speak in the international petroleum equipment industry."
Zhong Shude’s point of view coincides with Zhang Yongze. Zhong Shude said: "The oil drilling rig is one of the important equipments of the petroleum industry. Its development level is directly related to the voice and overall image of a country on the international stage. Previously, China has long been subject to the developed countries in the drilling equipment of special deep wells. Not only do they offer a price that is twice the cost of our own manufacturing, but they also have a long delivery time and are actually unwilling to provide us with such a product."
To this end, with the strong support of China National Petroleum Corporation, the “1.2 million-meter drilling rig” in 2006 was included in the important project of “Advanced Drilling Technology and Equipment”, a major project of the National “Eleventh Five-Year Plan” 863 Program. In the previous year, Zhong Shude and several senior experts in the field of oil drilling and petroleum equipment in China invested in the research and design of this project.

Petroleum equipment moves from a big country to a strong country

Due to the cheap labor and low energy resources, China has become a "world factory", especially in the automotive, textile, clothing and other fields. China's manufacturing industry seems to be low-cost, low-end, low-quality endorsements in the international market.
"For a long time, the petroleum equipment industry is facing the same problems." Zhong Shude said, "Half of the world's oil rigs are produced in China. China has become a major producer of oil rigs in the world and a major producer of petroleum equipment, but still far from Not the technical level of a strong country.” In Zhong Shude’s view, the gap between China’s petroleum equipment industry and the world’s power levels is mainly reflected in three aspects. First, because of the lack of high-end products for a long time, the overall program optimization of the products is not enough. Second, the lack of independent innovation, we seem to have been accustomed to catching up, often seeing what products have been developed abroad, and then take back a little change for my use, I am not accustomed to making original contributions to the progress of the global industry. Third, the quality and reliability of key equipment are not up to the international standards.
"But the successful development of the 12,000-meter drilling rig has made China's petroleum equipment manufacturing industry see new hopes." Zhong Shude said, "The successful development of the 12,000-meter drilling rig has not only enhanced China's competitiveness in the international oil and gas resources exploration market, but also made it China’s major oil equipment manufacturing country has reached the level of a strong oil equipment manufacturing country."
Zhong Shude said: "First of all, the first special deep well drilling rig in China will greatly enhance the brand value of Baoji Petroleum Machinery Co., Ltd., and at the same time increase the voice of China's petroleum equipment in the international market. Secondly, the scarcity of global oil and gas resources can be It is expected that the 12,000-meter rig will undoubtedly mean a considerable commercial prospect. It can not only meet the needs of exploration and exploitation of deep deep wells in the land, but also can be applied to the exploration and exploitation of deep-sea oil and gas resources by offshore drilling platforms. Good value for money wins the respect of the world, and this is also an inevitable choice for a manufacturing power to become a strong country."
