What are the main factors to consider when the first phase of West-to-East Gas Transmission Project turns to northern Shaanxi?

Before answering this question, let me explain that northern Shaanxi is also a gas-producing area in China, which is rich in oil and gas resources. The Shaanxi-Beijing line supplies gas to Beijing from Jingbian County in northern Shaanxi.

The first line of the West-East Gas Pipeline turned to northern Shaanxi, mainly considering that if the Shaanxi-Beijing line is short of gas supply to Beijing, the gas from the first line of the West-East Gas Pipeline can be used to supply Beijing. Of course, the pipeline of the Second West-East Gas Pipeline also passes through there, and now it has run through there and become an important natural gas distribution center.

If the Second West-East Gas Pipeline passes through Qaidam Basin, the gas pipeline will pass through Qinghai Province, but the gas supply of Qinghai Province and Lanzhou City has always been supplied by Saininglan pipeline, from Sebei oil and gas field in Qaidam Basin to Lanzhou, and then the inexhaustible gas from cities along Xining and Lanzhou will be transported to the pipeline of the western line through Lanyin pipeline (Lanzhou-Yinchuan).

Therefore, Qinghai does not need additional gas supply. On the contrary, there was no off-line transportation in Gansu because the gas volume in the first line of West-to-East Gas Transmission was not sufficient at that time. The Second West-East Gas Pipeline Project has set up several off-line stations in Gansu to supply gas to prefecture-level cities. Another factor is that the second line and the first line are parallel to the western crude oil and refined oil pipeline, and the four pipelines are together. If the third, fourth, fifth and sixth pipelines are all completed, it is possible to form a pipeline corridor with eight pipelines. Pipeline companies have divided regions (for example, pipelines in Gansu, Xinjiang and Qinghai are all managed by western pipelines), which is more convenient for management and inspection.

The Second West-to-East Gas Pipeline is of greater significance:

First of all, the construction of the East Section of the Second West-East Gas Pipeline Project highlights the central government's intention of expanding domestic demand, ensuring growth, ensuring employment and restructuring. The Second West-East Gas Pipeline is a landmark project in the central government's plan to expand domestic demand. In June last year, the state decided to implement a stimulus package to expand domestic demand, and urgently approved and started construction of a number of major energy projects, including the East Section of the Second West-East Gas Pipeline Project. The total investment of the whole Second West-East Gas Pipeline Project is 654.38+042.2 billion yuan; At the same time, the project construction will promote the development of domestic machinery, building materials, construction and natural gas utilization and other related industries, with direct investment exceeding 300 billion yuan.

Secondly, the Second West-East Gas Pipeline is an important project to improve people's livelihood. The project is planned to achieve full ventilation by the end of 20 1 1. In 20 12, China will add 30 billion cubic meters of natural gas, equivalent to half of the national natural gas supply in 2007, and the gas supply will be stable for 30 years. Cheap, clean and safe natural gas will significantly improve the lives of residents in 14 provinces and cities along the route. In particular, it is also meaningful to choose Shenzhen as the construction site of the eastern section. As one of the largest economic zones in China, the Pearl River Delta region has been in a backward state in natural gas development compared with other regions such as the Yangtze River Delta and Bohai Rim. At present, it is the only important natural gas consumption area in China that is not covered by large-scale natural gas pipelines, and it has to rely on liquefied natural gas (LNG) to import by sea for a long time.

Third, the Second West-to-East Gas Pipeline will promote the realization of China's energy-saving and emission-reduction targets. At present, in China's primary energy consumption, on the one hand, the proportion of coal consumption is as high as 70%, far exceeding the world average, which brings great pressure to the improvement of energy efficiency and environment in China; On the other hand, the consumption of natural gas as a clean energy only accounts for 3%, which is less than one eighth of the world average. The 11th Five-Year Plan proposes that the proportion of natural gas in the total primary energy consumption will increase to 5.3% within five years. It is estimated that the proportion of natural gas in China's primary energy consumption will increase by one to two percentage points after the Second West-East Gas Pipeline is put into operation. Compared with coal, 30 billion cubic meters of natural gas can reduce carbon dioxide emissions by 65.438+0.3 billion tons, sulfur dioxide by 65.438+0.44 million tons, dust by 660,000 tons and nitrogen oxides by 360,000 tons per year.

Finally, the Second West-to-East Gas Pipeline Project is conducive to ensuring China's energy security in terms of diversified supply. Compared with Russian, American and other big countries, China is not rich in natural gas reserves. According to statistics, the remaining recoverable natural gas reserves in China in 2007 were only 2.2 trillion tons, accounting for 1.25% of the global reserves. Compared with the limited supply, the demand for natural gas in China is increasing at an alarming rate year by year. In addition to domestic production and offshore transportation of LNG, importing from Central Asian countries through the West-East Gas Pipeline will provide China with a long-term and stable source of natural gas supply.

In addition, the main gas source of the Second West-East Gas Pipeline is Turkmenistan's natural gas, the supplementary gas sources are Kazakhstan and Uzbekistan, and the natural gas from Tarim gas field in Xinjiang and Changqing gas field in Shaanxi are used as emergency and safeguard gas sources. Obviously, from the geopolitical point of view, the project will play a strategic role in consolidating and strengthening the political and economic ties between China and Central Asian countries.
