China’s largest oil and gas field, the Changqing Oilfield operated by China National Petroleum Corporation (CNPC), has achieved a significant milestone by surpassing 1 billion tonnes in cumulative oil and gas equivalent production. This achievement underscores the field’s crucial role in ensuring national energy security and driving regional economic development.
A Major Milestone for National Energy Security
According to information obtained from CNPC on September 3, the Changqing Oilfield, located in the Ordos Basin, has continuously pushed the boundaries of oil and gas production. The field’s cumulative production of oil and gas equivalent has now exceeded 1 billion tonnes, marking a significant achievement for the country’s energy sector.
Overcoming Technological Challenges
The Changqing Oilfield faces unique challenges due to its geological characteristics. Over 95% of its reservoirs are classified as world-class low-permeability oil and gas reservoirs, where the flowability of oil and gas is extremely low. Despite these challenges, the oilfield has leveraged technological innovation to overcome a series of world-class exploration and development difficulties associated with low-permeability reservoirs.
From Marginal to Major Producer
Once considered a marginal field with little economic value for exploitation, the Changqing Oilfield has been transformed into China’s highest-yielding oil and gas field. Through advanced exploration and production techniques, CNPC has managed to turn the field into a major contributor to the country’s energy output.
Consistent High-Yield Production
The Changqing Oilfield has achieved remarkable stability in its production, with a consecutive 11-year streak of over 50 million tonnes in annual output. This consistent high-yield production has not only set new records in China’s oil and gas industry but also ensures a steady supply of energy resources for the nation.
Economic and Social Impact
The oilfield’s substantial production has had a profound impact on the regional economy. The field’s operations have created numerous job opportunities and stimulated economic growth in the surrounding areas. Additionally, the revenue generated from oil and gas production has been instrumental in funding various social and infrastructure development projects.
Latest Developments in Production
In recent months, the Changqing Oilfield has seen significant progress in its operations. In the eastern part of Gansu Province, a high-yield oil well was successfully put into production, achieving a daily output of 3.6 tonnes. Furthermore, the oilfield has completed the drilling of 435 shale oil wells and brought 797 new natural gas wells into production this year.
National Importance
The Changqing Oilfield’s annual oil and gas production now accounts for approximately one-sixth of the national output, highlighting its pivotal role in the country’s energy security. As China continues to seek ways to diversify its energy sources and enhance energy efficiency, the Changqing Oilfield remains a cornerstone of the nation’s energy strategy.
Conclusion
The achievement of surpassing 1 billion tonnes in cumulative production is a testament to the dedication and innovation of the Changqing Oilfield’s workforce. As China continues to face energy challenges, the oilfield’s consistent high-yield production and technological advancements will remain crucial in meeting the nation’s energy demands and ensuring a stable supply of oil and gas for years to come.
