on the evening of September 3, in the office of the national development and Reform Commission on Yuetan South Street in Beijing, a touch of setting sun passed through the glass and lengthened people's figure. Zhang Guobao, who is over 60 years old, took out several symphonic Peking Opera CDs of energy painting and handed them to the visitors one by one

Zhang Guobao, former director of the national energy administration, who has been in the field of energy for many years, is the author of the grand picture of energy. Taking shuidiaogue as the word brand, he described the construction achievements of major national energy projects in recent years. The west to east gas transmission project is an important chapter

"the west to east gas transmission project is the earliest and largest project in the western development. It can be said that the west to east gas transmission project has opened the prelude to the western development."

at present, it is a critical period for the national strategic West to east gas transmission project. The first-line project of West to east gas transmission has been completed and operated safely for 8 years; The third line project is "everything is ready, just waiting to start"; Preliminary planning is also being made for the fourth and fifth lines of the west to east gas transmission project

inside story of decision-making

: the west to east gas transmission project has been under construction for 12 years since it was started in 2000, and the first-line project has been in safe operation for 8 years. We know that you have participated in the decision-making and construction command of the project. At this time, how do you evaluate the strategic significance of the west to east gas transmission project

Zhang Guobao: when the west to east gas transmission project was started, the state leaders pointed out in their speech that it opened the prelude to the great development of the western region and painted a thick and heavy color on the land of China

the west to east gas transmission project has been in safe operation for eight years, benefiting 300 million people along the line of China, and really giving people a taste of clean natural gas with high calorific value and clean sweetness. At our age, we used to carry gas tanks. Now people in cities generally use natural gas

later, we built the Central Asia natural gas pipeline from Turkmenistan through Uzbekistan to Kazakhstan and then to China

I later recalled that if there was no West to east gas transmission, the Central Asian natural gas pipeline could not exist. Even if people were willing to sell natural gas to us, it might be difficult to make up their mind if China had not built such a long pipeline in China. At that time, there were skeptics. How could China buy natural gas from Central Asia? Such a long pipeline has to be built in the territory. In fact, it has been repaired in the territory at that time, otherwise it will enter the set state) the set temperature is as long as the part outside the territory is repaired and then connected with the pipeline in the territory

the Central Asia natural gas pipeline has become one of the most important channels for us to import natural gas from abroad. Now more than 70 billion cubic meters have signed contracts. At that time, the first line had been built. There were two pipelines on the first line, called pipe a and pipe B. now pipe C has begun to be built

recently, I accompanied the central leaders to Jiayuguan and Jiuquan. Along the line, I saw steel pipes lying there ready to be buried underground. The first, second and third lines all pass through Hexi corridor. In addition, on the basis of the first line of West to east gas transmission, the second and third lines of pipelines are planned to connect not only to Shanghai and Zhejiang in East China, but also to Hubei, Hunan, Jiangxi and Guangdong, as well as Shenzhen and Hong Kong. In addition, a branch pipeline has been built to Nanning. Now we have approved the construction of the third west east gas transmission line and a branch line, all the way to Sichuan. At present, natural gas has basically been networked throughout the country, and is ready to buy natural gas abroad

: the implementation of the west to east gas transmission project is not only a major event in the energy field, but also has been hotly discussed in the industry. As the project commander in chief, what do you think of the impact of this project on China's industry

Zhang Guobao: this influence is very important. The implementation of West to east gas transmission has greatly improved China's natural gas construction, equipment manufacturing and operation technology

when we just made the decision, we were all worried, because at that time, China had never engaged in such a long pipeline. As a measuring instrument, we suggested that we should simply establish a joint venture with foreign countries, and foreigners may be able to guide us. The formulation at that time was "two ends in hand, and the middle can not be." At the beginning, we talked about cooperation with foreigners, but the asking price was too high. Of course, as long as we had the best resources, we were unwilling. Later, we didn't reach an agreement. We decided to mainly adopt domestic technology

the initial pipeline of West to east gas transmission was called X70. At that time, China's technology could not solve X70, so we organized Baosteel and WISCO to tackle key production, and then we also attacked it. Subsequently, the continuous implementation of science and technology has driven industrial upgrading. At present, X70 and X80 steel pipes in the west to east gas transmission project, including the Central Asia natural gas pipeline, are domestic, filling the gap in China's iron and steel industry

the driving role of the industry also includes the later gas compressor unit. At that time, China's gas compressor units were 100% imported. The gas compressor was from Britain and the compressor was from the United States. At that time, we didn't dare to use domestic ones. Now, we also start to try domestic compressors, electric drive and gas drive. Some natural gas is also used for power generation, so some gas turbine electromechanical plants have been built. Taking advantage of this opportunity, we held a bidding, that is, the "market for technology" at that time. We tied the bidding to buy how many units of foreign companies and asked to transfer the technology to us. Taking this opportunity, we introduced the gas turbine technology of Ge, Siemens and Mitsubishi Heavy Industries of Japan, thus driving the domestic equipment manufacturing industry. The application of natural gas in the industrial field has also improved the quality of building materials such as ceramics and glass, which are used for hydrogen production in the petrochemical field

due to our experience in the west to east gas transmission project, our own construction team has done well in overseas projects, whether in Central Asia or Myanmar, which is also a very important achievement

adjust the energy structure

: you have been in charge of China's energy field for a long time. What are the specific manifestations of the irrationality of China's energy structure? What are the most effective means to change this unreasonable energy structure? Where is natural gas

Zhang Guobao: in my opinion, the implementation of the west to east gas pipeline has adjusted China's energy structure

we often say that China is inseparable from the energy structure dominated by coal. Of course, we still read this sutra now. At that time, the proportion of natural gas in China's energy structure was almost zero, only a little, that is, in Sichuan Basin, less than 1%

after the safe operation of the west to east gas transmission project, it has reached 100 billion cubic meters, including imported natural gas. Although the proportion of this in the whole energy structure is not high, we have tasted the sweetness of clean and convenient natural gas. At present, the enthusiasm for using natural gas remains high, not only for residents, but also for taxis in some cities. Natural gas filling stations are also used to fill gas instead of gasoline, because it is cheaper than gasoline and has less pollution emissions

in addition, the west to east gas transmission also promotes environmental protection. For example: for PM2 5. For the high problem, environmental protection experts believe that the proportion of automobile exhaust emission is the highest, accounting for about 35%. Therefore, at present, many cities are also promoting the use of natural gas vehicles

there are also some places that use natural gas to make some distributed energy, such as the building of Beijing gas company, which uses natural gas for heating, refrigeration and power supply. The experimental load of recommended materials in Guangzhou is about 70% and 90% of the range of tensile testing machine, and so is the university town

natural gas and electricity also need peak shaving, and we haven't done enough in this regard. Originally, the underground gas storage was built in Jintan, Jiangsu Province by using underground salt caverns, and some ing receiving stations were built, which can also play a certain role in peak shaving, so the ing industry was also driven. The benefits of West to east gas transmission are still fermenting
