The Sichuan Basin has added another deep integrated shale gas field with over 100 billion cubic meters.
August 14 , According to the news office of Sinopec, Sinopec " Deep Earth Project · Chuan-Yu Natural Gas Base " has achieved another major breakthrough ， submitted by Sinopec Southwest Petroleum Bureau Petroleum Bureau the Yongchuan shale gas field's newly proven geological reserves 124.588 billion cubic meters approved by the expert group of the Ministry of Natural Resources ， marks that China has another large-scale deep integrated shale gas field with over 100 billion cubic meters has been born ， effectively supporting the construction of the 100 billion cubic meters capacity base in Chuan-Yu, providing clean energy security for the development of the Yangtze River Economic Belt.
The Yongchuan shale gas field belongs to deep shale gas, located within Yongchuan District, Chongqing City, in the complex structural area of southern Sichuan Basin, the main part has a burial depth greater than 3500 meters 。 In 2016, the Southwest Petroleum Bureau deployed the first exploratory well Yongye 1HF in this area, achieving a major exploration breakthrough, thereby discovering the Yongchuan shale gas field. In 2019, an additional proven geological reserve of 23.453 billion cubic meters was approved by the expert group of the Ministry of Natural Resources. Subsequently, Sinopec continued to tackle the more challenging exploration and development in the central-northern Yongchuan area, ultimately achieving the overall proven reserves of the Yongchuan shale gas field this time, with total proven geological reserves reaching 148.041 billion cubic meters.
Innovative technology, makes deep shale gas "visible" and "accessible" 。 The research team collected a large amount of high-precision 3D seismic data of deep shale gas, organized multiple rounds of integrated geological, geophysical, and engineering joint research, forming new structural display mapping technology, high-precision imaging technology, etc., effectively solving problems such as "unclear visibility" and "inaccurate characterization" of deep shale gas. In addition, the team innovated differentiated transformation ideas for deep shale gas and developed a strong proppant volume fracturing process, allowing the shale gas buried underground to continuously flow out along these three-dimensional channels. This greatly improves the development efficiency of deep shale gas, significantly increasing the average economic recoverable reserves per well. ， Liu Wei, Executive Director and Party Secretary of Southwest Petroleum Bureau Co., Ltd., and representative of Southwest Oil and Gas Branch,
Sinopec stated, the shale gas distribution in the complex structural area of southern Sichuan Basin is wide and resource-rich, with broad prospects for exploration and development. The Yongchuan shale gas field is located in the core area of shale gas reserve increase and production in southern Sichuan, and the overall proven reserves achievement is of great significance to ensuring national energy security. Next, we will follow the idea of "build one area, evaluate one area, tackle one area", " steadily promote shale gas development in southern Sichuan, continuously improve reserve utilization rate and gas field recovery rate. ” Continuously promote deep natural gas exploration and development in the Sichuan Basin.
Sinopec The Sichuan Basin is rich in deep oil and gas resources with huge exploration potential. 。 "Deep Earth Project · Chuan-Yu Natural Gas Base" ， is an important part of Sinopec's "Deep Earth Project." Over the years, Sinopec has continuously promoted deep oil and gas exploration and development in the Sichuan Basin, in the field of deep conventional natural gas, successively discovered Puguang gas field, Yuanba gas field, and western Sichuan gas field; in the field of deep shale gas, has proven Weirong gas field, Qijiang gas field, Yongchuan gas field, and Hongxing gas field, ， four large deep shale gas fields with over 100 billion cubic meters each, which have important reference significance for the comprehensive liberation of shale resources and production capacity in China, making important contributions to green and low-carbon development. 威荣气田、綦江气田、永川气田、红星气田四个千亿立方米深层页岩气大气田，对我国页岩全面解放资源、解放产能具有重要借鉴意义，为绿色低碳发展作出重要贡献。
