Abstract

Abstract:

Tight reservoir is characterized by small pore throat size, complex pore structure, strong heterogeneity and large difficulty in characterization. Through systematically summarizing the development situation of current characterization technology of tight reservoir, some notable problems in the characterization of pore structure of tight reservoir were pointed out:(1) the scale study on representativeness of sample should be enhanced while emphasizing on resolution improvement; (2) the study on effective application scope of technology should ben strengthened while pursuing new technologies/methods; (3) The fusion of multi-scale qualitative and quantitative data should be strengthened while emphasizing on the quantitative characterization data combination, thus improving characterization precision. The future development of pore structure characterization technologies of tight reservoir was put forward:(1) to combine static characterization with dynamic evolution through multidisciplinary combination study, and achieve a comprehensive characterization of the pore structure; (2) to strengthen the macro-scale research in close combination with movable fluid evaluation, thus realizing the accurate prediction of scale effective reservoir body; (3) to strengthen the research on field application in close combination with reservoir stimulation measures, thus achieving the evaluation and optimization of engineering sweet spots.

Key words: tight reservoir, characterization of pore structure, technical error, nanoscale pore throat system, movable fluid

摘要：

致密储层孔喉尺寸小、孔隙结构复杂、非均质性强，表征难度大。通过系统梳理目前致密储层表征技术发展现状，指出致密储层孔隙结构表征需注意的几个问题：1强调提高分辨率的同时，需加强样品代表性尺度研究；2追求新技术/方法的同时，需加强技术有效适用范围研究；3强调定量表征数据拼接的同时，需加强多尺度定性与定量数据融合，提高表征精度。提出致密储层孔隙结构表征核心技术未来发展方向：1多学科联合攻关，静态表征与动态演化相结合，实现孔隙结构的全面表征；2加强宏观尺度研究，密切联系可动流体评价，实现对规模有效储集体的准确预测；3加强现场应用研究，紧密结合储层增产改造措施，实现对工程甜点的评价优选。
