Accelerate the construction of 100 billion natural gas production capacity base to build China's "gas Daqing"



On the morning of May 28, 2019, a special seminar titled "Development Countermeasures of Southwest Oil and Gas Field Company" was held. At the meeting, experts and scholars from domestic oil and gas fields sat together to discuss the exploration and development of conventional and unconventional gas in the Sichuan Basin.

"The Sichuan Basin is rich in resources and needs to plan ahead and speed up the construction of China's 'Southwest gas Daqing'." The voice of Zou Caineng, academician of the Chinese Academy of Sciences and vice president of the Research Institute of Petroleum Exploration and Development, made the participants feel fresh and fresh. It is precisely because of this sound that a realistic and lofty picture of China's "gas Daqing" is slowly opened...

Less than two years later, in 2021, the Sichuan Provincial government work report appeared the "figure" of China's "gas Daqing"; In March 2021, Peng Qinghua, secretary of the Sichuan Provincial Party Committee, once again emphasized that it is necessary to further promote the construction of "gas Daqing" as a strategic task concerning the overall situation.

So what does China's "Qi Daqing" look like? What are the prospects? Under the support of a series of policies, how will it be promoted? In response to a series of issues that people are concerned about, we try to find the answer to China's "Qi Daqing".

origin

Sichuan Basin has "bottom gas"

Sichuan Basin is located in southwest China, including the central and eastern part of Sichuan Province and most of Chongqing.

The resource evaluation of the Ministry of Natural Resources shows that the Sichuan Basin is rich in natural gas resources, with a total resource of 66 trillion cubic meters, about equal to the sum of the natural gas resources of Ordos, Tarim and Qaidam three basins. The proved reserves of 6.17 trillion cubic meters, with a proved rate of only 9.3%, are the most potential natural gas exploration and development basins in China.

Up to now, a total of 189 oil and gas fields and oil-bearing structures have been discovered in the Sichuan Basin, and the natural gas output accounts for about 1/4 of the national output, supporting Sichuan and Chongqing to become the regions with the widest gas use range and the highest gas rate in China.

At the same time, according to the statistics of petrochina Southwest Oil and Gas Field Company and Sinopec Petroleum Exploration and Development Research Institute, the natural gas production of Sichuan Basin in 2020 exceeded 55 billion cubic meters, and the natural gas production growth of Southwest Oil and Gas Field company accounted for 1/3 of the national growth.

The "China Natural Gas Development Report" (2019) pointed out that in the future, we will make every effort to build a natural gas production base in the Sichuan Basin. By increasing the development of deep gas, tight gas and shale gas, the natural gas production in Sichuan Basin will account for about 1/3 of the total domestic output in the future, and become the "southwest growth pole" for the development of China's natural gas industry.

Sichuan and Chongqing jointly build "gas Daqing"

In 2019, the National Energy Administration started the preparation of a special plan for the construction of 100 billion cubic meters of natural gas capacity in the Sichuan Basin - striving to reach 63 billion cubic meters of natural gas (shale gas) production in Sichuan and Chongqing by 2025; By 2035, China's first 100-billion-level natural gas production base will be built.

By 2020, the Outline of the Construction Plan for the Shuangcheng Economic Circle in Chengdu-Chongqing Region and its implementation opinions are clear, and the Sichuan-Chongqing region will comprehensively promote the development of oil and gas resources, build a national demonstration zone for comprehensive development and utilization of natural gas and a production capacity base of 100 billion square meters of natural gas, and build China's "gas Daqing".

On July 14, 2020, the Development and Reform commissions and energy Bureau of Sichuan and Chongqing officially signed the "High-quality Development Cooperation Agreement on Jointly Promoting Energy Integration in the Chengdu-Chongqing Economic Circle" in Chongqing, which is the first time that the energy authorities of Sichuan and Chongqing signed a cooperation agreement.

From December 2020 to March 2021, Sichuan Province and Chongqing Municipality successively issued the 14th Five-Year Plan for national economic and social Development and the outline of the 2035 vision goals, once again strengthening the building of China's "gas Daqing".

The release of a series of strategic plans has ushered in unprecedented historic opportunities for major oil and gas fields located in the Sichuan Basin.

Today, Sichuan and Chongqing are focusing on the overall situation in the Sichuan Basin, coordinating major oil and gas fields, and 20 major energy projects with a planned total investment of nearly 990 billion yuan are accelerating their landing. Among them, 710 billion yuan of investment funds will be used for the natural gas development in the Sichuan and Chongqing region, aiming to promote the Sichuan Basin to build a production capacity base of 100 billion cubic meters of natural gas (about 80 million tons of oil and gas equivalent), which means that the Sichuan Basin will continue to refresh the domestic natural gas production capacity record.

During the period, the two places will coordinate the exploration and development of natural gas resources in the Sichuan-Chongqing region, and actively play the leading effect of the construction of national shale gas demonstration zones in Changning, Weiyuan and Fuling - striving to reach 63 billion cubic meters (about 50 million tons of oil and gas equivalent) of natural gas (shale gas) production in Sichuan-Chongqing by 2025; By 2035, China's first 100-billion-level natural gas production base will be built, and the Sichuan Basin will continue to consolidate its position as the country's largest natural gas production base.

"In the current period of historical opportunity for Sichuan and Chongqing to jointly build a 'gas Daqing', the natural gas purification General Plant of petrochina Southwest Oil and Gas Field Company combined with its own business and advantages, put forward to 'ensure that the upstream production capacity is fully played, ensure that the new area's production capacity is reached on time' as its responsibility, focusing on the three major production fields of 'high sulfur upper production, Dachuan middle development, and eastern Sichuan rolling exploration'. Gather strength to do a good job in the 'oil company' model reform, digital transformation and upgrading, 'production' to 'business' transformation of three major development ideas and directions, at the same time in the Sichuan and Chongqing area of the oil enterprises' development 'and' big cooperation 'under the background, maximize the advantages of the plant purification specialization." China Petroleum Southwest oil and gas field company natural gas purification plant director Wang Jun said.

Brave mission to accelerate progress

At present, only CNPC in the Sichuan Basin natural gas exploration and development enterprises include petrochina Southwest Oil and Gas Field Company, Zhejiang Oil Field Company, Daqing Oil Field Company, Sinopec Southwest Oil and Gas Company, Jianghan Oil Field Company, Zhongyuan Oil Field Company. The construction of China's "gas Daqing", naturally, the Southwest oil and gas field company's figure.

It is reported that in 2012, Southwest Oil and Gas Field Company discovered Longwangmiao gas reservoir group in Moxi block of Anyue gas field, which is the largest Marine carbonate gas reservoir in China. In 2013, Xiangguo Temple gas storage, the first gas storage in Southwest China, began gas injection. In 2014, oil and gas exploration in the Lower Permian Qixia Formation in the northern part of western Sichuan made a major breakthrough. In 2016, for the first time in the Devonian system of Sichuan Basin, industrial air flow was obtained. The first industrial gas well was drilled in volcanic rocks in 2018. As of 2019, 2 trillion atmospheres of reserves have been formed...

Moreover, it took 45 years for the Southwest Oil and Gas Field Company to increase its gas production from 100 million cubic meters to 10 billion cubic meters. It took 13 years to go from 10 billion cubic meters to 20 billion cubic meters; It took only three years for the production to reach 30 billion cubic meters in 2020.

At present, in the major projects jointly promoted by Sichuan and Chongqing, the construction of Changning - Weiyuan national shale gas Demonstration Zone of Southwest Oil and Gas Field Company will play a leading role and is accelerating.

In 2020, Southwest Oil and Gas Field Company produced 10.0019 billion cubic meters of shale gas, becoming China's largest shale gas development enterprise with an annual output of gas.

The relevant person in charge of Sichuan and Chongqing shale gas frontline headquarters said: "At present, our drilling rig increased from 38 at the beginning of 2018 to the peak of 169, a total of 1,281 drilling Wells, 849 production Wells, an average annual penetration of more than 1.4 million meters, and won the first domestic '4 million square' shale gas platform and 59 million square platforms, daily production for three consecutive years to achieve 10 million square level across, annual production for three consecutive years increased by more than 40%, It has successfully built China's largest shale gas production and comprehensive utilization base, and actively contributed to the completion of China's 'gas Daqing' by 2025."
