| 摘 要： | 页岩气储层以低孔隙度、低渗透率为主要特征,在开采过程中需通过实施水力压裂改造储层以形成工业产能。页岩储层脆性的评价对于合理设计压裂方案具有从而提高压裂作业效率、节约开发成本具有重要意义。地球物理技术可为页岩气储层脆性的定量评价提供数据支持,主要包括岩石物理实验、地球物理测井和地球物理反演等。对相关研究方法进行了系统总结,并以四川盆地某区块的页岩储层脆性预测为例说明了其实际应用。

| Abstract: | Low porosity and permeability are main characteristics of shale gas reservoir, its reservoir properties need be changed through hydraulic fracturing to achieve industrial capacity in developing. Estimation of rock brittleness plays an important role in designing the hydraulic fracturing to enhance efficiency and save cost of development. Geophysical technologies including rock physics experiment, logging and inversion can offer the data that needed by brittleness evaluation of shale gas reservoir. In this paper, related research methods were systemically summarized ,and an example of shale gas reservoir brittleness estimation in Sichuan basin was presented. |
