Core Insights - A significant discovery of a giant shale oil field with a geological reserve of 158 million tons has been made in Daqing, Heilongjiang, marking a crucial development for China's energy landscape [1][3]. Group 1: Economic Impact - The potential economic value of the 158 million tons of reserves is estimated to be close to several hundred billion RMB, sufficient to support the construction of multiple million-ton capacity shale oil bases [3]. - If developed on a large scale, this resource could contribute an annual production of one million tons of oil, equivalent to creating a medium-sized oil field, enhancing China's energy security [5]. Group 2: Technological Advancements - The Daqing exploration team has successfully activated oil flow in underground shale layers using key technologies such as horizontal drilling and multi-stage fracturing, indicating a breakthrough in unconventional oil and gas exploration technology in China [4]. - This achievement signifies that China has begun to master a low-cost, large-scale development model for shale oil, which could reshape the country's approach to energy extraction [4]. Group 3: Strategic Importance - The discovery serves as a "strategic reserve" in China's energy map, providing a vital boost to the country's energy self-sufficiency, especially as it remains the world's largest crude oil importer [5]. - The Daqing oil field has initiated preliminary experimental development, aiming to establish a replicable shale oil development model during the 14th Five-Year Plan period [5].
