| 中文摘要: |
| 以鄂尔多斯盆地华庆地区长6致密砂岩储层为例,研究了影响致密砂岩储层微裂缝发育程度的复杂微观地质因素。应用灰关联分析法，揭示了微裂缝发育程度与各影响因素的关系。结果表明，灰关联分析法可应用于致密砂岩储层微裂缝成因研究，确定影响致密砂岩储层微裂缝发育程度的主要微观地质因素及其影响程度，与实测结果较吻合，为建立微裂缝发育程度表征参数体系提供了理论依据。 |
| 英文摘要: |
| This study focuses on complex microscopic geological factors that influence development degree of micro cracks in tight-sandstone reservoirs. Taking Chang 6 tight sandstone reservoir of the Huaqing area in Ordos Basin as an example, we reveal the relationship between the development of micro cracks and various influencing factors using the method of grey association. The results show that this approach is applicable for such issues, which allows us to determine the major micro geologic factors that influence crack development and its degrees. They fairly coincide with the real measurements, and provide a theoretical basis for characterizing the micro cracks in the target reservoirs. |
