PetroChina's largest overseas natural gas project has transported 61.7 billion cubic meters of gas to China

this year marks the 10th anniversary of the natural gas cooperation between China and Turkmenistan. 21st Century Business Herald visited PetroChina's largest overseas natural gas project company, Amu Darya gas company

according to the data, Amu Darya natural gas company was established in September 2007, mainly responsible for the organization and implementation of natural gas exploration and development projects on the right bank of the Amu Darya River in Turkmenistan

the relevant person in charge of Amu Darya natural gas company introduced to the 21st Century Business Herald that the Amu Darya project is by far the largest onshore natural gas exploration and development cooperation project of PetroChina, and it is also the only onshore block natural gas product sharing contract signed between Turkmenistan and foreign oil and gas companies

according to PetroChina, Amu Darya natural gas company has produced 66.759 billion cubic meters of feed gas and exported 61.703 billion cubic meters of commodity gas since it was put into operation on December 14, 2009, as of 12:00 on August 2

10 years of exploration to obtain a solid resource base

tracing back to history, the Amu Darya River project is an important international cooperation project closely linked with the Central Asia natural gas pipeline, and was born under the joint promotion of the leaders of China and Turkey

guojiaofeng, assistant director of the Institute of resources and environmental policy of the development research center of the State Council, analyzed the 21st Century Business Herald that in the field of natural gas, China and Turkey have complementary advantages in resources and markets

among them, Turkmenistan, as the fourth largest natural gas resource country in the world, is rich in natural gas resources and urgently needs panacryl reg; It is another kind of commercialized PLGA suture. Through export diversification, it breaks the restriction of a single export bottleneck and obtains more economic benefits. As the second largest economy in the world, China has a huge demand for clean energy. At the same time, based on the consideration of energy security, it also needs to obtain long-term and stable energy supply

due to the good geographical advantages of the two countries, the two sides realized the docking of natural gas strategies and gradually carried out specific energy cooperation negotiations under the promotion of the negotiation between the leaders of the two countries in 2005

on April 3, 2006, the then president of China Hu Jintao and the then president of Turkmenistan Niyazov signed in Beijing the "general agreement between the Chinese government and the government of Turkmenistan on the implementation of the China Turkmenistan natural gas pipeline project and the sale of Turkmenistan natural gas to China", which became the first agreement in Chinese history signed jointly by the president and a foreign head of state

according to the agreement, Turkmenistan will export 30billion cubic meters of natural gas to China every year through the Central Asia natural gas pipeline in the next 30 years. The gas source is divided into two parts: one is 13billion cubic meters of natural gas produced by PetroChina in the contract block on the right bank of the Amu Darya River, and the other is 17billion cubic meters of natural gas supplied by Turkmenistan's national natural gas Konzern

therefore, on July 17, 2007, PetroChina signed a product sharing contract for the "bagtyjiarlyk contract area (i.e. the block on the right bank of the Amu Darya River in Turkmenistan)" and a 17billion cubic meter natural gas purchase and sales contract with the State Administration for oil and gas resources management and utilization under the president of Turkmenistan and Turkmenistan's national natural gas Konzern

in August of that year, PetroChina obtained the exploration and development license and other documents issued by President Berdymukhamedov of Turkmenistan, and the right bank project of Amu Darya River was officially launched

Amu Darya natural gas exploration and development project is located in bagtyjiarlyk contract area on the right bank of Amu Darya River in Turkmenistan, including block a and block B

in this regard, caolaiyong, manager of the Exploration Department of Amu Darya natural gas company, introduced to the 21st Century Business Herald that block a is relatively mature. Previously, some old wells have been exploited, mainly for the repair of old wells, supplemented by the development of new wells; While block B is an unexplored block, which requires a lot of exploration investment

according to the product sharing contract signed by China and Turkey in July 2007, the exploration period of bagtyjiarlyk contract area a is 6 years and that of bagtyjiarlyk contract area B is 10 years. After the expiration, the development area is reserved for natural gas exploitation, and all non development areas are returned to the resource countries

according to Cao laiyong, the exploration of block a has been completed in 2013 and the land has been successfully withdrawn. The old wells successfully repaired in block a since 2009 have produced gas and transported commercial gas to China through the Central Asia natural gas pipeline at the end of the year

in contrast, block B is "high temperature, high pressure and high sulfur", with complex geological conditions and harsh surface and climatic environment, which brings great difficulties to early exploration and later development. However, Amu Darya River Company innovated its theoretical understanding and promoted technological upgrading. The "key technology and application of exploration and development of large-scale undersalt carbonate gas fields on the right bank of Amu Darya River" for this research won the second prize of the 2014 National Science and technology progress award

by virtue of technological tools, two 100 billion cubic meters of gas fields with large gentle slope integration have been found in the middle of the block that was originally considered by other countries to be only scattered gas, and a capacity of 10 billion cubic meters has been built through rolling development. The eastern and Western wings achieved exploration breakthroughs in places not found in the former Soviet Union, and 10 medium and large potential gas reservoirs with reserves of more than 200billion cubic meters were found in the East. Seven gas bearing structures with reserves of nearly 100 billion cubic meters have been found in the West. Exploration is fast and efficient, which provides a resource base for gas production and supply

it is expected to transmit 13billion cubic meters of gas to China this year

in the past decade, the Amu Darya River project has achieved remarkable results. It is said that its energy density exceeds all the current ternary systems, and it will often encounter the production challenge of natural gas supply protection in winter

as the first natural gas product sharing project outside PetroChina, the Amu Darya River project has formed six 100 billion cubic meters of atmospheric areas, with an annual gas production capacity of 17 billion cubic meters, and built the first overseas natural gas strategic livelihood guarantee project with a capacity of 10 billion cubic meters, 10 million tons and 500000 tons of condensate

according to PetroChina, since its launch in July 2007, the Amu Darya River project has supplied 61.7 billion cubic meters of gas to China and produced 980000 tons of condensate. Therefore, the project is called "a model of opening up and cooperation of Turkmenistan" by President Berdymukhamedov of Turkmenistan

nevertheless, the challenges faced by Amu Darya River in winter cannot be ignored. The peak valley difference in the demand of China's natural gas market in the light and peak seasons is particularly large, which brings great difficulties to the natural gas production of the Amu Darya River project

taking Beijing as an example, the monthly gas consumption in winter is more than 4 times that in summer; In terms of hot and cold days, Beijing's gas consumption reached 120million cubic meters on January 23, 2016, 12.6 times that of 9.5 million cubic meters on July 23 of the same year

only during the financing meeting in the same section, the relevant person in charge of Amu Darya natural gas company can introduce that natural gas production is sustainable, and stable and continuous gas supply is the ideal state of natural gas production. This is not only the best for equipment and facilities configuration and gas reservoirs, but also conducive to reducing costs and achieving the best benefits

due to the huge difference between peak and valley in winter and summer, Amu Darya River company must allocate production capacity according to the maximum demand in winter. In addition to the increase in investment, the improvement of production capacity also involves a series of early-stage investment and construction, such as reserve exploration and discovery, new well development, surface widening costs several 10 times or even hundreds of times higher, engineering construction, treatment facilities construction, etc., which is a huge system project that requires close cooperation of all disciplines in the whole industrial chain

in recent three years, in cold winter seasons, the daily supply of soil gas has exceeded 100million cubic meters, twice that of summer, accounting for the first place in the domestic large pipe daily supply

during the heating season from November 1, 2016 to March 5, 2017, Amu Darya natural gas company supplied 5.1 billion cubic meters of gas to China, successfully completing the task of ensuring supply in winter and spring

According to the 21st Century Business Herald, Amu Darya natural gas company plans to produce 12.5 billion cubic meters of feed gas and export 11.7 billion cubic meters of commodity gas in 2017

as of August 2, 12: 00, 2017, the cumulative production of feed gas was 8.678 billion cubic meters, and the export of commercial gas was 8.012 billion cubic meters
