Abstract

Abstract: In 2019, PetroChina Changqing Oilfield Company discovered the Qingcheng shale oil field with 1 billion tons of estimated oil resources in Ordos Basin. However, it remains controversial whether its petroleum resources are tight oil or shale oil. Based on systematically analyzing the geological characteristics of unconventional reservoirs in the Member 7 of Yanchang Formation, it is believed that the entire Member 7 of Yanchang Formation is a set of fine-grained sediments, characterized by thin sand body for a single stage, low ratio of total sandstone thickness to formation thickness and source-reservoir integration, with the development of typical shale oil inside. The in-depth understanding of enrichment mechanism and characteristics of shale oil has driven the Changqing oilfield to improve the exploration and development methods and management thinking, and implement integrated operation, platform management, factory operations, information support, full life cycle assessment and other measures. By striving to make breakthroughs in multi-disciplinary technical researches, this study develops key technologies for "sweet spot" evaluation, high-quality fast drilling and completion technologies for horizontal wells, volume fracturing technology for subdivision and cutting of horizontal wells and other special technologies, thus promoting the exploration and development of shale oil in the Member 7 of Yanchang Formation in Ordos Basin to achieve important breakthroughs; meanwhile, a million-ton-level shale oil demonstration plot has been set up. Ordos Basin will be one of the most important areas for increasing oil production in China. The shale oil in the Member 7 of Yanchang Formation is determined as the most practical field. It is planned that the production of the shale oil in the Member 7 of Yanchang Formation will reach 500×10⁴ t in 2030, which is of great strategic significance to support China's stable crude oil production and guarantee the national energy security.

Key words: tight oil, shale oil, source-reservoir integration, intra-source accumulation, Member 7 of Yanchang Formation, Ordos Basin

摘要： 2019年中国石油长庆油田公司在鄂尔多斯盆地发现庆城10亿吨级页岩油田，但其石油资源属于致密油还是页岩油尚存争议。基于延长组7段（长7段）烃源岩层系非常规油藏地质特征的系统分析，长7段整体为一套细粒沉积，单期砂体厚度小、砂地比低、源-储一体，认为其内部发育典型的页岩油藏。页岩油富集机理与成藏特征的深化认识带动长庆油田转变了勘探开发方式与管理思路，实行一体化运行、平台化管理、工厂化作业、信息化支持、全生命周期考核等多项措施；开展多学科联合技术攻关，形成"甜点"评价关键技术、水平井优快钻完井技术、水平井细分切割体积压裂技术等特色技术，助推鄂尔多斯盆地长7段页岩油勘探开发取得重要突破，并建成百万吨级页岩油示范区。鄂尔多斯盆地是中国未来石油上产最主要的地区之一，长7段页岩油是最现实领域，规划2030年长7段页岩油产量将达到500×10⁴t，对支撑中国原油稳产和保障国家能源安全具有重大战略意义。
