A look: the weapon can be more profitable
Zi Yan: "If you want to do something good, you must first sharpen your tools." For the oil industry, oil equipment is a weapon. The development history of the modern petroleum industry projects the progress trajectory of petroleum equipment. Without high-quality and suitable equipment for protection, it can only hope that the "oil" will sigh and the people will suffer. Then, what kind of requirements do the current oil industry put on equipment, and what more benefits does the weapon need? Cippe2010 provides an image of market demand.
Entering the 70,000 square meters exhibition hall, the beautifully designed exhibition booths should not be overwhelmed, and all kinds of high-precision equipment and machinery are in full swing. The U.S.-led Western Enterprise Group has brought the world’s latest and most advanced petroleum and petrochemical technology equipment and research and development results, especially to address the challenges of global climate change, and vigorously develop low-carbon economy, high-tech, high-intelligence original technology equipment products. and service. For example, a high-efficiency turbo compressor exhibited by Siemens on site can use the most economical way to obtain the pressure required to deliver gas, which greatly reduces carbon emissions. It is also a Fortune 500 company, flammable gas, toxic gas. The latest gas detectors developed by Honeywell, the world's leading manufacturer of oxygen detection systems, also made their debut.
High-tech, low-energy, and safe oil equipment is the signature of overseas manufacturers and the new favorite of the international market. It reflects the modern civilization's high concern about the sustainable development of human beings in the face of environmental protection and safety faced by the petroleum and petrochemical industries. For petroleum equipment manufacturers, the focus of the market is the direction of product upgrades.
Technology is the key to upgrading products. In some key technologies, it is necessary to catch up with the world's advanced technology and strive to improve the contribution rate of high-tech and high-value-added products. This is the direction of China's petroleum equipment manufacturing enterprises.
Although compared with well-known overseas equipment manufacturers, the technical level of domestic enterprises has to continue to improve. However, since the "11th Five-Year Plan", China's petroleum equipment manufacturing industry has entered a benign track of sustained and rapid development, with frequent highlights. The marine pipe winch that Gem Machinery Company has just independently developed and developed at this exhibition is a representative. Gem Machinery Company introduced that this new product not only fills the gap of domestic technology, but also reaches the advanced level of international similar products – making up for the lack of “short board†of core technology and fist products with independent intellectual property rights, and expanding equipment technology to marine areas. The "long board" of protection is the key to China's petroleum equipment industry's participation in international competition.
Second look: how high is the threshold
According to the organizers of the exhibition, the biggest highlight of this exhibition is that the equipment manufacturing branch of China National Petroleum Corporation has been unveiled in the form of “China Petroleum Equipmentâ€.
Indeed, the "China Petroleum Equipment" combination booth is composed of gemstone machinery, gemstone steel, Bohai equipment, Jichai Power and other 12 companies arranged in a 4,000-square-meter booth to form a gemstone flower, fully demonstrating the core of China's petroleum equipment. Increased competitiveness and a jump in industry size.
Shouldn't it be packed? This is no longer a problem in the face of today's market competition. What is more worth thinking about is how to install and how to coordinate the operation after the installation. Because the market competition in the modern sense is no longer a contest for enterprises to fight alone, the market threshold of modern significance is not only the competition of funds.
At the exhibition, the pavilions of various countries in the West are undoubtedly the most luxurious and most eye-catching booths: the “Red Maple Leaf†of the Canadian pavilion is shining, the flag of the German pavilion is neat and tidy, and the American pavilion subtly marks the stars. Placed on top of everyone, and every stand of the British pavilion is covered with the proud flag of the British Empire. Internationally renowned exhibitors such as Russia, Russia's National Petroleum Pipeline Company, Siemens, Eaton, Sandvik, South Korea's Samsung, ABB, etc., have demonstrated the high standards of competition in the current international petroleum equipment market.
The characteristics of the industry and the laws of the market prove that the petroleum equipment industry, which is an investment-intensive industry, has a large demand for fixed assets investment funds and liquidity, and has a large market risk. Only by becoming bigger and stronger, and doing better and better, can we get the first chance in the international market game.
Third look: How big is the cake?
The reporter learned that the three-day exhibition attracted 1,200 exhibitors from 37 countries and regions around the world, with an exhibition area of ​​70,000 square meters and a professional audience of 40,000.
The reporter also found that in addition to the traditional oil equipment manufacturing enterprises, there have been some new faces at the exhibition, including many "big sons" in related industries. For example, one of the top 50 engineering machinery manufacturers in the world, "Sany Heavy Industry", the specifications of the exhibition is very eye-catching. In the interview, the reporter learned that since last year, Sany Group has taken rigs, derricks, base systems and other petroleum equipment machinery as a new chapter in the company's business development, and hopes to rely on the company's own comprehensive strength to make great achievements.
How big is the “cake†in the oil equipment market? According to the year-end statistics of global oil production and oil and gas reserves released by the US Oil and Gas Journal on December 21, 2009, it is estimated that global oil production in 2009 will decrease by 3.2% year-on-year, and OPEC oil production will fall by 8.4% to 1.475 billion tons, which is close to 5. The lowest output in the year. In fact, due to the financial crisis, in 2009, global oil companies and service companies reduced their investment, and technical equipment export orders were significantly reduced. Some of them were performing and the projects were put on hold. The so-called "lip-tooth cold", the export market of China's oil drilling equipment is also affected, domestic demand is shrinking, the reality is very serious.
Will the predicament of "more porridge" appear? The outlook is bright. The International Energy Agency raised its 2010 oil consumption forecast on March 12 and pointed out that the world oil demand in 2010 increased by 1.6 million barrels compared with last year, of which China accounted for 1/3 of global demand increase, and daily demand will reach 903. Million barrels. Schlumberger, the world's largest oilfield technology services company, predicts that global drilling activities will begin in 2010. At the same time, we have seen several large-scale projects including Chevron Texaco's Gao Geng project in Australia, the Rumaila oil project in Iraq, the 17th block of Total in Angola and the 31 block project of BP. Investment projects will be launched in 2010, which provides opportunities for global petroleum equipment manufacturers.
Perhaps it is not appropriate to use the "cake" to compare the equipment market. Because the market is changing, money is flowing. Similarly, the three-day exhibition is only an ecological slice of the international petroleum equipment market, but its sample for the industrial transformation and upgrading of the petroleum and petrochemical equipment manufacturing industry in the post-financial crisis period is still worthy of our reference.
On March 22nd, the sun, which was covered by dust for many days, finally showed his face. The 10th China International Petroleum & Petrochemical Technology and Equipment Exhibition (hereinafter referred to as cippe2010) was kicked off at the Beijing New National Exhibition. As the first in Asia and one of the world's top four oil exhibitions, cippe2010, the products and technologies displayed at the exhibition undoubtedly represent the latest trends and future trends of the international petroleum equipment market. Go, go see it together, the show begins!
