为稠油绿色开采提供"中国方案" 当前，全球超稠油开发普遍依赖热采技术，而传统工艺采用燃气或燃煤锅炉产汽热采，存在能耗高、碳 排放量大的问题。作为我国最大的整装浅层超稠油生产基地，风城油田的稠油虽品质优良，但黏稠度极 高，需借助高品质过热蒸汽进行降黏和驱动才能开采。 中国石油集团公司高级技术专家、新疆油田公司首席技术专家孙新革强调，该项目实现了稠油开采过程 中化石燃料的规模化可再生能源替代，为我国稠油绿色开发提供了可复制的新业态、新模式与新动能， 更构建了一套完整的稠油光热开采技术体系，为国际、国内稠油绿色开采树立了科学样板。 此次投产的塔式水工质高温光热项目，采光面积达5.15万平方米。项目采用先进小型定日镜聚光系统， 可稳定产出305℃的高品质过热蒸汽，直接满足稠油热采的核心需求；更具突破性的是，项目创造性地 将高温光热制蒸汽技术与稠油地下蒸汽腔储能相结合，即便在夜间无光照条件下，也能通过蒸汽腔持续 释放白天储存的热量加热油藏，实现"光尽其用，零碳采油"的经济环保目标。 风城油田作业区相关负责人介绍，该项目投运后，每年可生产5.2万吨零碳过热蒸汽，替代天然气近392 万立方米，所产蒸汽用于稠油热采可实现零碳 ...

Core Viewpoint - The world's first heavy oil thermal extraction solar thermal replacement demonstration project has been launched in Xinjiang, marking a significant technological breakthrough in China's green and low-carbon transformation of oil and gas development [1][3]. Group 1: Project Overview - The solar thermal development project is located in the Fengcheng oilfield operation area of Karamay City, Xinjiang, covering an area of 150,000 square meters with a solar collection area of 51,500 square meters [3]. - The project utilizes 23,712 lightweight modular heliostats to reflect sunlight to a 113-meter high heat collector, producing high-temperature steam at 305°C, which is injected underground to meet the thermal extraction needs of heavy oil [3][5]. - The project innovatively uses underground steam chambers for thermal energy storage, allowing for continuous heat release during nighttime, achieving the economic and environmental goal of "maximizing solar use and zero-carbon oil extraction" [3]. Group 2: Technological Advancements - The small heliostat technology used in the project has a tracking precision of 1.2 milliradians, significantly higher than the common 2.0 milliradians in commercial power plants, with a solar reflection efficiency exceeding 95%, placing these metrics at an international leading level [5]. Group 3: Environmental Impact - Heavy oil, characterized by high viscosity and poor fluidity, accounts for over 70% of global reserves. Traditional thermal extraction methods using gas or coal boilers are energy-intensive and have high carbon emissions [8]. - The Fengcheng oilfield, as China's largest shallow heavy oil production base, previously consumed nearly 1 billion cubic meters of natural gas and about 300,000 tons of coal annually for thermal extraction [8]. - With the completion and operation of the high-temperature solar thermal project, it is expected to produce 52,000 tons of zero-carbon superheated steam annually, replacing approximately 3.92 million cubic meters of natural gas, equivalent to the annual gas demand of 20,000 households [8].
