| 摘 要： | 较强的应力敏感性是裂缝性储层的重要特征之一,并直接关系到裂缝性储层开采方案的制定.基于Brown ＆ Scholz粗糙面接触理论,从细观上建立了裂缝面弹塑性接触模型,并依据此模型进行了裂缝应力敏感性分析.结果表明,裂缝的开度或渗透率越大,则相应储层的应力敏感性愈强.该模型的建立对裂缝性储层开采方案的合理制定具有一定的指导意义. |
| 关 键 词： | 裂缝性储层 弹塑性接触 应力敏感性 裂缝开度 渗透率 |

| Abstract: | Strong stress sensitivity is an important character of fractured reservoirs and will affect exploitation project.In this paper,elastic-plastic contacting model for natural rock fractures is built on the base of microscopic B&S contacting theory.With this model,the relationship between fracture permeability and actual stress can be analyzed quantitatively.The result shows that the larger the permeability is,the stronger the stress sensitivity of the reservoir is. |
| Keywords: | fractured reservoir elastic-plastic contacting stress sensitivity |
