中国第一大油气田五年生产油气当量超3亿吨

Core Insights - China's largest oil and gas field, Changqing Oilfield, is projected to produce over 300 million tons of oil and gas equivalent from 2021 to 2025, demonstrating strong operational momentum [1][3]. Group 1: Production and Development - Changqing Oilfield has addressed the challenges of low permeability, low pressure, and low abundance in oil and gas reservoirs through in-depth research on oil and gas distribution patterns [1]. - The oilfield has established five oil-rich areas with a scale of ten billion tons and five gas-rich areas with a scale of trillion cubic meters, laying a solid resource foundation for increased production [1][3]. - The gas field's comprehensive decline rate has been reduced to 19.5%, with stable annual natural gas production capacity maintained at 50 billion cubic meters [3]. Group 2: Technological Advancements - Changqing Oilfield has implemented key projects focusing on low-permeability oil extraction technology and has enhanced the management of aging wells [3]. - The oilfield has built China's largest shale oil production base, achieving over 300,000 tons of growth for five consecutive years, with a historical high expected in shale oil production by 2025 [3]. Group 3: Environmental Initiatives - Over the past five years, Changqing Oilfield has proactively shut down more than 14,000 oil and gas wells and has given up 460,000 tons of oil and gas equivalent in ecologically sensitive areas [3]. - The oilfield has planted over 2.1 million trees and established 2,900 solar power stations, with a total installed capacity of 364,000 kilowatts and cumulative power generation exceeding 1.1 billion kilowatt-hours, promoting a multi-energy complementary development model [3]. Group 4: Contribution to Energy Security - Changqing Oilfield has maintained a stable production of over 60 million tons of oil and gas equivalent for six consecutive years, providing a solid guarantee for China's energy security [3].
