一头扎进非常规油藏研究领域,河南油田非常规储层评价研究专家黎明就没给自己设终点。14年来,他 研发出一套数字化油藏技术,找到了非常规油藏储层的特点和储量动用最大化的规律,为老油田可持续 发展开拓了新阵地。他也被评为河南油田首届科技英才、中国石化集团公司劳动模范,并获得中国石化 集团公司东湾1HF井区长7致密油高效储量发现转化二等奖。他常说:"就是要拿出绣花功夫,才能绣出 老油田的美好未来。" 细"织"井网 "网"住更多优质储量 "开发工作的主要任务就是把优质储量转化为产量,而如何实现储量的有效转化恰恰是最难的。"讲起动 用旬宜探区优质储量的思路,黎明的眉头紧锁。 旬宜探区的油藏属于致密油,采出油本身就难度很大。加上探井所在的井台地表沟壑纵横,建井场难度 也很大。工作还没展开,一道道难题就横亘在面前。 "乱麻总能理出头绪,慢慢来。"黎明说。旬宜探区的井台面积只有1.1万平方米,在这么小的范围如何 部署更多的井?黎明背着井位图、卫星定位仪等踏勘工具,深入位于陕西西北部大山里的旬宜探区,实 地了解情况。 钻井过程中,钻头在地下穿越,看不见、摸不着,是否能"钻"到目的层很难得知。黎明和团队成员为每 一口井量身定制了三 ...

Core Viewpoint - The Xinjiang oil field has established the first national-level continental shale oil demonstration area in China, focusing on both technical and economic feasibility for shale oil extraction [2][4]. Group 1: Technical Challenges and Solutions - The extraction of continental shale oil presents significant challenges, including deep burial, thin oil layers, and the need for precise drilling and high-pressure fracturing [2]. - Over the past decade, Xinjiang oil field has made breakthroughs in shale oil extraction, addressing three core challenges: identifying sweet spots, reservoir modification, and efficient development [3]. - The company has developed a set of advanced technologies, including a tracking technology for drilling and a combination fracturing technique that enhances flow efficiency [3]. Group 2: Economic Viability and Management - The Xinjiang oil field has implemented a "one full six optimization" production organization model to ensure economic viability in shale oil extraction, focusing on full lifecycle management and market-oriented operations [4]. - The introduction of market mechanisms has led to a 40% reduction in single well investment costs through project-based management [5]. - The demonstration area has improved drilling and fracturing efficiency, achieving a 58% completion rate for drilling in the past five years [6]. Group 3: Environmental Considerations - The company has adopted CO2-driven oil extraction methods and waste recycling initiatives to enhance ecological benefits in shale oil production [6]. - The implementation of platform-based development has reduced land usage by 50%, allowing multiple wells to be deployed from a single platform [6].
