The cumulative output of China's first large-scale shale gas field is 30 billion cubic meters per day, which can meet the gas consumption of 34 million households
Hualong.com-New Chongqing client at 16:33 on May 11 (Chief reporter She Zhenfang correspondent Dai Ying) Hualong.com-New Chongqing client was informed that today (11), China's first large-scale commercial shale gas field ——Fuling Shale Gas Field in Jianghan Oilfield of Sinopec has a cumulative production of 30 billion cubic meters of shale gas. The current daily gas production is 17 million cubic meters, which can meet the daily gas demand of 34 million households. In order to accelerate the restoration of the national economy, ensure energy security, and build Beautiful China contributes.
The Fuling Shale Gas Field is located in Chongqing City and is one of the important gas sources for the Sichuan-East Gas Pipeline in China. It is also an important resource base for Sinopec's "gasification of the Yangtze River Economic Belt" action. The successful development of this gas field has established a new Milestones have opened a new journey for China's energy revolution.
Facing the world-class problem of shale gas development, Sinopec started from scratch and continued to explore, innovate and integrate comprehensive evaluation of shale gas reservoirs, excellent and fast drilling of horizontal well groups, staged fracturing gas test and production development of long horizontal wells The five major technological systems with Fuling shale gas development characteristics and green development are the first national shale gas demonstration areas in China, providing valuable experience for global shale gas development. At present, the Jiaoye 1HF well in the gas field has been continuously producing for 2680 days, and the Jiaoye 6-2HF well has a cumulative production of more than 310 million cubic meters. It continues to maintain the longest domestic shale gas well development time and the highest record of single well cumulative production.
Aiming at efficient development, the core technology and key equipment will be upgraded. According to the "research-test-promotion" model, Sinopec pioneered the domestic three-dimensional shale gas development model in the Fuling shale gas field. The recovery rate of the Jiaoshiba three-dimensional development zone reached 38.6%, reaching the domestic leading and international advanced level. The second-generation integrated geosteering technology promotes core technologies such as drilling and fracturing. The single-well productivity in the old gas field has increased by 30%, and the cost of single-well gas testing has dropped significantly. At the same time, new equipment and tools such as drilling, fracturing, and gas testing were introduced to form a domestic high-tech equipment application system. The project of “Efficient Exploration and Development of Fuling Large Marine Shale Gas Field” won the first prize of National Science and Technology Progress Award.
It is reported that since this year, in order to ensure the supply of natural gas and help the enterprises along the Yangtze River Economic Belt to resume production and achieve production, the Fuling Shale Gas Company of Jianghan Oilfield launched the "100-day attack and create efficiency" action, continuously breaking the shortest record of the gas field drilling cycle, and greatly improving the quality of storage The drilling encounter rate, the total number of fracturing sections reached 2.5 times the same period last year, and the pipeline has transported 2.1 billion cubic meters of natural gas along the Yangtze River Economic Belt through Sinopec Sichuan-East Gas Pipeline.
