提出了一种泥页岩脆裂性质的表征方法---脆裂指数法，介绍了脆裂指数的测定流程和步骤。这种方法操作简便、对样品的大小、外形无特殊要求，对于泥页岩样品测试具有普遍意义。实验数据表明，泥页岩脆裂指数与孔隙度、比表面积大小呈正相关关系。从测定流程、方法、实验数据以及文献分析来看，泥页岩脆裂指数具有表征孔隙发育程度及其内部结构，尤其是微孔隙、微裂隙的潜在应用价值。初步探讨了脆裂指数在表征泥页岩内部结构性质以及气体解吸行为研究等方面的应用前景。

The paper presents one kind of brittle shale characterization method:brittle index, and introduces the determination process and procedure for the index. This method is simple to operate, and has no special require-ments for sample size and shape, hence has universal significance for shale sample test. Experimental data show that the brittle index is positively correlated to porosity and specific surface area. According to measurement process, method, experimental data and literature analysis, the brittle index can characterize the extent and in-ternal structure of porosity, especially the potential application for micro pores and cracks. The prospects for the application of brittle index in the studies of shale internal structure and gas desorption are discussed preliminarily.
