Abstract:

PetroChina Xinjiang Oilfield Company is carrying out a pilot test of concentrated solar power direct steam generation，in conjunction with existing gas-fired steam boilers，to produce low-carbon，high-quality steam for super-heavy oil production using SAGD technology. This has exemplary significance for the integration of oil and gas field exploration and development using renewable energy technology. Under the double carbon initiative，Xinjiang Oilfield is facing the challenge of reducing natural gas consumption and CO₂ emission while maintaining super-heavy oil production. Through combining solar energy concentrating and heating technology，green electricity + electrode molten salt heating technology，and high-temperature heat storage technology，renewable energy supply configuration schemes for different scenarios are proposed for the use of steam injection in shallow heavy oil exploitation，which will provide a specific road map and solution for the scale application of concentrating solar power technology in the heavy-oil operation areas of Xinjiang Oilfield. The schemes will reduce self-consumption of natural gas and provide low-cost steam，and has guiding significance for low carbon，sustainable exploration and development of heavy-oil fields.

摘要：

新疆油田公司近期在某井区开展高温光热制蒸汽与注汽锅炉耦合的先导试验，为稠油蒸汽辅助重力泄油（SAGD）开发提供低碳高品质蒸汽。先导试验的开展对油气勘探开发与新能源技术的融合具有先行示范意义。“双碳”目标下新疆油田公司稠油生产面临减少天然气消耗，降低二氧化碳排放的挑战。结合太阳能聚光集热技术、绿电+电极熔盐加热技术、高温储热技术，提出不同场景下浅层稠油开采中注汽工艺的新能源供能配置方案。为太阳能高温光热技术在新疆油田稠油作业区规模化应用提供了具体思路与解决方法，在减少自用天然气的同时尽可能降低蒸汽成本，对稠油油田低碳可持续开发具有重要指导意义。
