长庆油田连续6年保持高产规模

Core Insights - Changqing Oilfield has achieved an annual oil and gas equivalent production of over 60 million tons, maintaining this high production level for six consecutive years since becoming China's first large-scale oil and gas field of this size in 2020 [1] Group 1: Production Achievements - The exploration and development area of Changqing Oilfield is primarily located in the Ordos Basin, characterized by low pressure, low permeability, and low abundance, making development challenging [2] - In 2024, Changqing Oilfield's annual oil and gas equivalent production is expected to reach a historical high, accounting for one-sixth of the total domestic oil and gas production for that year [2] Group 2: Technological Advancements - Changqing Oilfield has increased its efforts in exploration, development, and technological innovation to overcome the challenges of "three lows" in oil and gas reservoirs [2] - The oilfield has established China's first 3 million-ton shale oil production base and a 50 billion cubic meter gas area [2] - A hydraulic fracturing test site has been built at the Qingcheng shale oil platform to enhance single well production and promote the effective development of shale oil [2] - The first "zero-support agent" fracturing operation for coalbed methane was implemented at the Shaanxi Mizhi coalbed gas production site, marking a significant transition in fracturing methods [2] - In the Longdong Yuan 284 block, a demonstration area for the transformation of ultra-low permeability oil reservoirs to water injection development has been established, increasing oil extraction speed by four times and annual production from 48,000 tons to 196,000 tons [2]
