陆相页岩油录井重点发展领域与技术体系构建

Key Development Fields and Construction of Technical System for Logging of Continental Shale Oil

  • 摘要: 我国陆相页岩油勘探开发刚起步,而录井作为地质工程一体化的纽带,其重点发展领域尚不明确,没有建立系统的采集与评价技术体系,在一定程度上制约了页岩油录井技术的发展与录井作用的充分发挥。为此,在系统分析国内外页岩油录井技术现状与页岩油地质工程一体化需求的基础上,从矿物组分定量分析与有利岩相随钻识别、储集性与含油性评价、可动性评价、可压性评价等4个方面深入分析了录井评价的内容、难点及存在的不足,提出应重点发展漫反射傅里叶变换红外光谱(DRIFTS)、钻井液含油性核磁共振在线录井与岩样T1T2二维核磁共振录井、录井岩石力学3个领域。在此基础上,根据针对性、有效性、经济性的原则,分中低成熟度、中高成熟度2种类型,建立了基于储集性、含油性、可动性、可压性、可钻性评价的录井技术体系,以期促进页岩油录井技术的进步和指导生产实践。

     

    Abstract: The research on continental shale oil has just started in China. The key development fields of logging, the link of geology-engineering integration, are not yet clear. There is no systematic establishment of a corresponding collection and evaluation technical system, which restricts the development and full exploitation of shale oil logging to a certain extent. After a systematic analysis of current status of shale oil logging and the requirements of the geology-engineering integration of shale oil, the contents, difficulties, and shortcomings of logging evaluation were analyzed in detail from the four aspects, including a quantitative analysis of mineral components and identification of favorable lithofacies while drilling, reservoir and oil-bearing property evaluation, mobility evaluation, and fracrability evaluation. It is proposed that the development of diffuse reflection infrared Fourier transform spectroscopy (DRIFTS), online nuclear magnetic resonance (NMR) logging for the oil-bearing property of drilling fluids, T1-T2 two-dimensional NMR logging of rock samples, and logging rock mechanics should be emphasized. On this basis, according to the principles of pertinence, effectiveness and economy, continental shale oil can be divided into two types: medium-low maturity and medium-high maturity, and the technical system for logging based on the evaluation of reservoir property, oil-bearing property, mobility, fracrability, and drillability was developed, in a way that can guide the development and production practice in shale oil logging.
